When a patient has glaucoma, cataracts and irregular astigmatism at the same time, it is often difficult to achieve satisfactory results. Purpose: This study intends to describe a case of a patient with glaucoma, irregular astigmatism, and cataract who was successfully treated. Additionally, it can serve as a useful source of inspiration for the future care of patients like this. Case Presentation: A 24-year-old male with keratoconus in the past. He had undergone a corneal crosslinking operation in the right eye and a penetrating keratoplasty in the left eye due to his long history of keratoconus in both eyes. Right now, the keratoconus in that eye is stable. Unfortunately, he has now been diagnosed with open-angle glaucoma and complicated cataracts in both eyes, and he was admitted to our hospital for surgery. The right eye had significant irregular astigmatism, which was discovered during the preoperative assessment, and the implantation of a Toric intraocular lens was unable to produce good results. Finally, we chose to perform EXPRESS glaucoma drainage device implantation + phacoemulsification + intraocular lense (ZEISS CT ASPHINA 409MP) implantation. The patient had stable postoperative astigmatism with rule thanks to the traction effect of the scleral flap suture. Astigmatism was typically stable six months after surgery, and the corrected visual acuity with glasses had improved to 20/25. Conclusion: This patient suffers from cataracts, keratoconus, glaucoma, and irregular astigmatism. Due to the interconnectedness of these four disorders, simultaneous success is challenging. We realized that surgically induced astigmatism, frequently affects vision early after filtering surgery for glaucoma patients. In the instance of this patient, we tightly sutured the scleral flap and using tractive action, established regular astigmatism. After the patient’s astigmatism stabilized, optometry was given to correct the vision. This technique should result in much better visual acuity. Finally, it came to pass.展开更多

Combined cataract surgery and glaucoma with Ex-PRESS~ P-50 model placed under scleral flap was performed.·RESULTS: Out of 40 eyes of 40 patients(55% male and45% female) completed the study during one-year follow-up. The mean of age was 76.6 ±11.02 y. The intraocular pressure(IOP) decreased significantly during the 12-month follow-up from 23.5 mm Hg to 16.8 mm Hg(Wilcoxon signed ranks test, P 〈0.001). A 59.5% of patients did not need any topical treatment, 10.8% of them needed one active principle, 27% needed two active principles, and 2.7% of them needed three active principles for successful IOP control(〈21 mm Hg).·CONCLUSION:Combinedsurgeryofphacoemulsification with Ex PRESS~ P-50 lowers IOP from the preoperative baseline and reduces significantly the number of antiglaucoma active principles for IOP control after the operation.展开更多

The primary efficacy estimate was identified by weighted mean difference of the percentage of intraocular pressure reduction(IOPR%) from baseline to end-point, the percentage of number of glaucoma medications reduction from pre-to post-operation, and the secondary efficacy evaluations were performed by odds ratio(OR) and 95% confidence interval(CI) for complete and qualified success rate. Besides, ORs were applied to assess the tolerability of adverse incidents. Meta-analyses of fixed or random effect models were performed using Rev Man software 5.2 to gather the consequences. Heterogeneity was evaluated by Chi^2 test and the I^2 measure.RESULTS: Ten studies enrolling 3108 patients were included. The combined consequences indicated that both glaucoma and combined cataract and glaucoma surgery significantly decreased IOP. For deep sclerectomy vs deep sclerectomy plus phacoemulsification and canaloplasty vs phaco-canaloplasty, the differences in IOPR% were not all statistically significant while trabeculotomy was detected to gain a quantitatively greater IOPR% compared with trabeculotomy plus phacoemulsification. Furthermore, there was no statistical significance in the complete and qualified success rate, and the rates of adverse incidents for trabeculotomy vs trabeculotomy plus phacoemulsification.CONCLUSION: Compared with trabeculotomy plus phacoemulsification, trabeculectomy alone is more effective in lowering IOP and the number of glaucoma medications, while the two surgeries can not demonstrate statistical differences in the complete success rate, qualified success rate, or incidence of adverse incidents.展开更多

Baseline demographic and ocular characteristics were recorded,as well as intraocular pressure, number of glaucoma medications, and visual acuity postoperatively with 12-month follow-up. Treatment failure was defined as less than 20% reduction in IOP from baseline on two consecutive visits(at 1, 3, 6, or 12 mo postoperatively),IOP ≥21 mm Hg or ≤5 mm Hg on two consecutive visits, or additional glaucoma surgery performed within12 mo after PCE/ECP.·RESULTS: Overall, mean medicated IOP was reduced from 16.65 mm Hg at baseline to 13.38 mm Hg at 12mo(P 0.0001). Mean number of glaucoma medications was reduced from 1.88 medications at baseline to 1.48 medications at 12mo(P =0.0003). At 3mo postoperatively,the success rate was 73.6%(95%CI: 63.3, 81.5), 57.1% at6mo(95% CI: 46.3, 66.6), and 49.7% at 12mo(95% CI:38.9, 59.6). Patient demographic characteristics were not associated with treatment success. The only ocular characteristic associated with treatment success was a higher baseline IOP.· CONCLUSION: Combined PCE/ECP surgery is an effective surgical option for the reduction of IOP and medication burden in glaucoma patients. Patients withhigher baseline IOP levels are most likely to benefit from this procedure.展开更多

The quality of included trials was evaluated according to the guidelines developed by the cochrane collaboration. And the outcomes estimating efficacy and safety of two different surgical treatments were measured and synthesised by Rev Man 5.0.· RESULTS: Five randomized controlled trials were selected and included in Meta-analysis with a total of468 patients(468 eyes) with both PACG and cataract. We found that Phacotrabe had a greater intraocular pressure(IOP) lowing effect [preoperative IOP: weighted mean difference(WMD)=0.58, 95% confidence intervals(95% CI,-0.53 to 1.69), P =0.31; postoperative IOP: WMD =1.37,95% CI(0.45 to 2.28), P =0.003], a lower number of antiglaucoma medications [risk ratio(RR)=0.05, 95% CI(0.02 to 0.18), P 〈0.00001] needed postoperatively and less serious damage of optic nerve [RR =0.48, 95% CI(0.21 to 1.07), P =0.07], but a higher risk of complications[odds ratio(OR)=0.04, 95% CI(0.01 to 0.16), P 〈0.00001]compared with Phaco. The rest studies indicated that there had no significantly difference between the two surgical methods for postoperative best-corrected visual acuity(BCVA) [WMD =-0.05, 95% CI(-0.14 to 0.05), P =0.32] and loss of visual field [RR=1.06, 95% CI(0.61 to1.83), P =0.83].·CONCLUSION: Phaco alone compared with Phacotrabe had a better effect in IOP reduction, whereas the securitydecline. Considering the number of sample size, our results remains to be further studied.展开更多

Within 3 mo before the PPI, 7 cases accompanied with glaucoma maintained carteolol hydrochloride for lowering intraocular pressure, and 1 case maintained glucocorticoid for anti-inflammation. The baseline characteristics, treatment processes, and outcomes of enrolled cases were retrospectively analyzed. Hematoxylin and eosin(HE) staining was performed to reveal the histopathological changes of iris tissues.RESULTS: Iris hemorrhage was the only intraoperative complication observed in 2 cases. After the surgery, normal intraocular pressure, right position of intraocular lens, and improved visual gain [best corrected visual acuity(BCVA)>0.5] were achieved. Postoperative keratic precipitates was observed in 2 cases, which was recovered within 1 wk. During the follow-up of 5-10 y, no recurrence of uveitis was found in 27 cases(96.43%). Uveitis only recurred in one case with the onset of ankylosing spondylitis. HE staining showed iris stroma(all samples), pigment cell hyperplasia in pigment epithelium(n=9) and stroma(n=19), inflammatory cell infiltration in iris(n=7), and neovascularization in iris surface(n=2).CONCLUSION: PPI improves the visual gain and prevents the long-term recurrence of uveitis in patients with uveitis-induced cataract, including those with preoperative intraocular pressure abnormality(glaucoma) and inflammation(active uveitis). Uveitis presents stroma atrophy, pigment cell hyperplasia, and inflammatory cell infiltration, even in a quiet state.展开更多

Method: A quick procedure using the CO2 laser was adapted for patients with small eyes undergoing laser-assisted cataract surgery using the Catalys system. The UniPulse CO2 laser (Nidek) was used for laser lateral canthotomy on patients with small palpebral fissures to allow fitting of the Liquid OpticTM Interface eyepiece. Results: Lateral canthotomies were performed on 19 women and 7 men (ages ranged from 45 to 93 years) with lower eyelid lengths equal to or shorter than 32 mm who then underwent femtosecond laser-assisted cataract surgery. A total of 33 eyelids received laser lateral canthotomy with the CO2 laser;only one eyelid had lateral canthotomy with cold-steel tenotomy scissors. Dockings were completed for all 34 eyes with eyelids receiving lateral canthotomies. The 33 eyes with eyelids that received laser canthotomy with the CO2 laser had successful femtosecond laser-assisted cataract surgery. The one eye with the eyelid that received cold-steel canthotomy could not have femtosecond laser-assisted cataract surgery despite successful docking because of pupillary constriction. The findings were statistically significant;Fisher Exact Test showed a p-value of 0.0294. Conclusion: Laser lateral canthotomy with CO2 laser is a safe and effective method to allow docking and completion of femtosecond laser-assisted cataract surgery.展开更多

The rate of transparent grafts was 62% after an average follow-up of 19 months. 60% of the patients restored their vision to 0.1 and better. The rate of transparent grafts and visual improvement did not correlate with the mode of cataract extraction; however, the extracapsular procedure had less vitreous during operation than the intracapsular modality did. The authors recommend that the combined operation be adopted for patients with corneal opacity and cataract, and preferably using the extracapsular mode.展开更多

The medical history, demographic information, and clinical characteristics of each case were recorded. Data regarding changes in vision, intraocular pressure(IOP), the number of glaucoma medications, and the evolution of the disease after surgery were reported. RESULTS: Three patients, with open angle glaucoma and cataracts underwent combined excisional goniotomy and MSICS without adverse events. All patients had improvement in vision compared to baseline measurements. The range of IOP at baseline was from 14 to 18 mm Hg and decrease to a range of 10 to 14 mm Hg after one year of follow-up. Additionally, two patients also decreased their dependence on IOP-lowering medications at the last follow up visit with one patient maintaining baseline level of medication use.CONCLUSION: A combination of excisional goniotomy and MSICS illustrates both the safety and efficacy to treat patients with visually significant cataract and glaucoma. This procedure allows for a more cost-effective surgical approach that matches the needs of resource strained territories around the globe.展开更多

Methods: A total of 90 patients with DC were randomly divided into control group (n=45) and observation group (n=45) according to the lottery method. Both groups were treated with conventional therapy. On this basis, the control group underwent phacoemulsification combined with vitrectomy. The observation group was treated with Fuming tablets on the basis of the control group. The levels of β2-MG, HbA1c, NO, MDA and SOD in peripheral blood were measured in all subjects. Result: Before treatment, there were no significant difference in serum levels of β2-MG, HbA1c, NO, MDA and SOD between the two groups. The levels of β2-MG, HbA1c, NO and MDA in the two groups after treatment were significantly lower than those before treatment. And the levels of β2-MG, HbA1c, NO and MDA of the observation group was notably lower than those of the control group. After treatment, the levels of SOD in the two groups were notably higher than those before treatment. And the levels of SOD of the observation group was notably higher than those of the control group after treatment. Conclusion: After phacoemulsification combined with vitrectomy, supplemented with Fuming tablet treatment can effectively reduce serum levels of β2-MG and HbA1c to improve the degree of fundus lesions in DC patients;reduce serum MDA and NO levels, increase the concentration of SOD, DC patients to restore the antioxidant energy.

文摘AIM:To evaluate corneal astigmatic outcomes of femtosecond laser-assisted arcuate keratotomies(FAKs)combined with femtosecond-laser assisted cataract surgery(FLACS)over 12mo follow-up.METHODS:Totally 145 patients with bilateral cataracts and no ocular co-morbidities were recruited to a singlecentre,single-masked,prospective randomized controlled trial(RCT)comparing two monofocal hydrophobic acrylic intraocular lenses.Eyes with corneal astigmatism(CA)of>0.8 dioptres(D)received unpaired,unopened,surface penetrating FAKs at the time of FLACS.Visual acuity,subjective refraction and Scheimpflug tomography were recorded at 1,6,and 12mo.Alpins vectoral analyses were performed.RESULTS:Fifty-one patients(61 eyes),mean age 68.2±9.6y[standard deviation(SD)],received FAKs.Sixty eyes were available for analysis,except at 12mo when 59 attended.There were no complications due to FAKs.Mean pre-operative CA was 1.13±0.20 D.There was a reduction of astigmatism at all post-operative visits(residual CA 1mo:0.85±0.42 D,P=0.0001;6mo:0.86±0.35 D,P=0001;and 12mo:0.90±0.39,P=0.0001).Alpins indices remained stable over 12mo.Overall,the cohort was under-corrected at all time points.At 12mo,61%of eyes were within±15 degrees of pre-operative astigmatic meridian.CONCLUSION:Unpaired unopened penetrating FAKs combined with on-axis phacoemulsification are safe but minimally effective.CA is largely under-corrected in this cohort using an existing unmodified nomogram.The effect of arcuate keratotomies on CA remained stable over 12mo.
文摘AIM:To evaluate the postoperative intraocular lens(IOL)rotational stability and residual refractive astigmatism following combined 25-gauge vitrectomy and cataract surgery with implantation of a plate haptic toric IOL.METHODS:In this retrospective case series,32 eyes of 32 patients underwent a combined 25-gauge vitrectomy and phacoemulsification for vitreoretinal diseases and cataract with regular corneal astigmatism of at least 1 diopter(D).A plate haptic toric IOL(AT Torbi 709M,Carl Zeiss Meditec AG)was implanted in all eyes.The outcome measures were rotational stability and refractive astigmatism up to 6mo postoperatively as well as the best corrected visual acuity(BCVA).RESULTS:Preoperative refractive astigmatism was 2.14±1.17 D,which was significantly reduced to 0.77±0.37 D six to eight weeks postoperatively and remained stable throughout the observation period(0.67±0.44 D at three months and 0.75±0.25 D at six months;for all groups:P<0.0001 compared to baseline).BCVA improved significantly from 0.36±0.33 logMAR preoperatively to 0.10±0.15 logMAR following surgery(P=0.02).Mean IOL axis deviation from the target axis was 3.4°±2.9°after six to eight weeks and significantly decreased over time(2.4°±2.6°six months after surgery;P=0.04).In one patient IOL,re-alignment was performed.CONCLUSION:Corneal astigmatism is significantly reduced following combined 25-gauge vitrectomy and cataract surgery.The plate haptic toric IOL position and axis remain stable during the observation period of six months.
文摘Significance: So far, many scholars have studied the astigmatism caused by glaucoma surgery, but they cannot provide enough useful help for the clinic. When a patient has glaucoma, cataracts and irregular astigmatism at the same time, it is often difficult to achieve satisfactory results. Purpose: This study intends to describe a case of a patient with glaucoma, irregular astigmatism, and cataract who was successfully treated. Additionally, it can serve as a useful source of inspiration for the future care of patients like this. Case Presentation: A 24-year-old male with keratoconus in the past. He had undergone a corneal crosslinking operation in the right eye and a penetrating keratoplasty in the left eye due to his long history of keratoconus in both eyes. Right now, the keratoconus in that eye is stable. Unfortunately, he has now been diagnosed with open-angle glaucoma and complicated cataracts in both eyes, and he was admitted to our hospital for surgery. The right eye had significant irregular astigmatism, which was discovered during the preoperative assessment, and the implantation of a Toric intraocular lens was unable to produce good results. Finally, we chose to perform EXPRESS glaucoma drainage device implantation + phacoemulsification + intraocular lense (ZEISS CT ASPHINA 409MP) implantation. The patient had stable postoperative astigmatism with rule thanks to the traction effect of the scleral flap suture. Astigmatism was typically stable six months after surgery, and the corrected visual acuity with glasses had improved to 20/25. Conclusion: This patient suffers from cataracts, keratoconus, glaucoma, and irregular astigmatism. Due to the interconnectedness of these four disorders, simultaneous success is challenging. We realized that surgically induced astigmatism, frequently affects vision early after filtering surgery for glaucoma patients. In the instance of this patient, we tightly sutured the scleral flap and using tractive action, established regular astigmatism. After the patient’s astigmatism stabilized, optometry was given to correct the vision. This technique should result in much better visual acuity. Finally, it came to pass.

文摘Dear Editor,Two cases of primary angle-closure glaucoma(PACG)with persistent shallow anterior chamber after phacoemulsification,intraocular lens(IOL)implantation and goniosynechialysis(GSL)were presented.PACG,which mainly presents with mechanical obstruction of the trabecular meshwork,is clinically characterized by elevated intraocular pressure(IOP)secondary to the apposition of peripheral iris or a synechial closure of the angle[1].A previous study reported that angle-closure glaucoma eyes experienced widening and deepening of anterior chamber angles following cataract extraction and IOL implantation,which could probably normalize the IOP[2].A randomized controlled trial demonstrated that in comparison with laser peripheral iridotomy(LPI),clear-lens extraction showed greater advantages in efficacy and cost-effectiveness and could be proposed as the first-line initial treatment for PACG[3].

文摘BACKGROUND During anesthesia administration for cataract surgery,low pH of proparacaine may induce pain or complications such as corneal damage and poor wound healing,with the use of additional drops intraoperatively increasing the risk of complications.Accordingly,there is a clinical need for adjuncts to local anesthesia needs to improve the efficiency of anesthesia and reduce the required amount of intraoperative proparacaine.AIM To identify a method of anesthesia for geriatric cataract phacoemulsification that provides more efficient analgesia and improves clinical efficacy.METHODS A total of 130 geriatric patients with cataracts who attended Hebei Eye Hospital from December 2020 to December 2022 were included in the present study.Patients were divided into the proparacaine surface anesthesia(SA)group(65 cases)and the compound acupuncture-medicine anesthesia group(CAMA group,65 cases).Patients in the CAMA group were provided acupuncture analgesia in addition to SA.Preoperative anxiety[Self-Rating Anxiety Scale(SAS)score and state anxiety inventory(SAI)score],intraoperative stress,vital signs,analgesia,and cooperation,as well as postoperative adverse events,were compared between groups.RESULTS More marked reductions in anxiety were observed among patients in the CAMA group,with corresponding reductions in SAS and SAI scores.During the operation,no change in the secretion of E,NE,or Cor group compared to the preoperative period was observed in the CAMA,which was markedly lower than that in the SA group.Heart rate,blood pressure,and respiratory rate were more stable intraoperatively in the CAMA group.In addition,the incidence of intraoperative pain and the number of additional doses of anesthesia required in the CAMA group were markedly lower than in the SA group.Accordingly,patients in the CAMA group were able to avoid eye movements and eyelid closing leading to greater cooperation with surgeons during surgery.Furthermore,marked reductions in intraoperative adverse effects were observed in the CAMA group,indicating greater overall safety.CONCLUSION Proparacaine SA combined with acupuncture as an analgesic provides improved analgesia with greater safety compared to surface anesthesia with proparacaine during geriatric cataract phacoemulsification.
文摘AIM:To investigate the efficacy and safety of combined phacoemulsification and goniosynechialysis with or without endoscopic cyclophotocoagulation(PGE group and PG group)for the treatment of patients with coexisting primary angle-closure glaucoma(PACG)and cataracts.METHODS:The clinical data of patients with PACG and cataract were retrospectively reviewed.There was a total of 88 eyes in the study and were divided into two groups,42 eyes in PGE group and 46 eyes in PG group.Surgery success cumulative survival,preoperative and postoperative intraocular pressure(IOP),number of IOPlowering medications,best corrected visual acuity(BCVA)in the two groups were observed for more than 12 mo and compared within each group and between two groups.RESULTS:The mean IOP in PGE group declined from24.9 mm Hg preoperatively to 14.1 mm Hg at the first month after operation(P<0.001)and at the last visit 16.2 mm Hg(P<0.001).Meanwhile PG group also showed significant decrease,from 24.1 mm Hg preoperatively to 13.0 mm Hg at Imo after operation(P<0.001)and 15.3 mm Hg at the last visit(P=0.004).The mean medications reliance reduced in both groups,in PGE group was reduced from 1.62 preoperatively to 0.13 at the last visit(P<0.001),in PG group from 0.87 to 0.10(P<0.001).At the last visit,BCVA increased from 0.21 to 0.60 in PGE group(P<0.001)and from 0.24 to 0.67 in PG group(P<0.001).The success rate of PGE group at 1 mo was95.2%,then decreased to 70.7%at the last visit,whereas in PG group,the success rate at 1 mo was 100%,at the last visit was 73.4%.CONCLUSION:PGE shows promise for PACG patients with cataracts to reduce IOP,lighten the medication burden and improve visual acuity,and PG still has its value in specific patients.
文摘AIM: To evaluate the efficacy and safety of glaucoma drainage device Ex-PRESS~ P-50 for combined cataract surgery and glaucoma.·METHODS: Patients having cataract and open angle glaucoma or patients with open advanced glaucoma which needed two or more antiglaucoma medications were included. Combined cataract surgery and glaucoma with Ex-PRESS~ P-50 model placed under scleral flap was performed.·RESULTS: Out of 40 eyes of 40 patients(55% male and45% female) completed the study during one-year follow-up. The mean of age was 76.6 ±11.02 y. The intraocular pressure(IOP) decreased significantly during the 12-month follow-up from 23.5 mm Hg to 16.8 mm Hg(Wilcoxon signed ranks test, P 〈0.001). A 59.5% of patients did not need any topical treatment, 10.8% of them needed one active principle, 27% needed two active principles, and 2.7% of them needed three active principles for successful IOP control(〈21 mm Hg).·CONCLUSION:Combinedsurgeryofphacoemulsification with Ex PRESS~ P-50 lowers IOP from the preoperative baseline and reduces significantly the number of antiglaucoma active principles for IOP control after the operation.

文摘AIM: To conduct a systematic review and quantitative Meta-analysis of the efficacy and safety of combined surgery for the eyes with coexisting cataract and open angle glaucoma.METHODS: We performed a systematic search of the related literature in the Cochrane Library, PubM ed, EMBASE, Web of Science databases, CNKI, CBM and Wan Fang databases, with no limitations on language or publication date. The primary efficacy estimate was identified by weighted mean difference of the percentage of intraocular pressure reduction(IOPR%) from baseline to end-point, the percentage of number of glaucoma medications reduction from pre-to post-operation, and the secondary efficacy evaluations were performed by odds ratio(OR) and 95% confidence interval(CI) for complete and qualified success rate. Besides, ORs were applied to assess the tolerability of adverse incidents. Meta-analyses of fixed or random effect models were performed using Rev Man software 5.2 to gather the consequences. Heterogeneity was evaluated by Chi^2 test and the I^2 measure.RESULTS: Ten studies enrolling 3108 patients were included. The combined consequences indicated that both glaucoma and combined cataract and glaucoma surgery significantly decreased IOP. For deep sclerectomy vs deep sclerectomy plus phacoemulsification and canaloplasty vs phaco-canaloplasty, the differences in IOPR% were not all statistically significant while trabeculotomy was detected to gain a quantitatively greater IOPR% compared with trabeculotomy plus phacoemulsification. Furthermore, there was no statistical significance in the complete and qualified success rate, and the rates of adverse incidents for trabeculotomy vs trabeculotomy plus phacoemulsification.CONCLUSION: Compared with trabeculotomy plus phacoemulsification, trabeculectomy alone is more effective in lowering IOP and the number of glaucoma medications, while the two surgeries can not demonstrate statistical differences in the complete success rate, qualified success rate, or incidence of adverse incidents.
文摘●AIM:To compare efficacy of coaxial microincisions(1.8 mm,2.2 mm)and small incisions(3.0 mm)on phacoemulsification combined with trabeculectomy for primary angle-closure glaucoma(PACG)with cataract.●METHODS:Ninety-six patients(96 eyes)with PACG and cataract were recruited and randomly divided into three groups between January 2015 and June 2017.Group A(3.0 mm incision),B(2.2 mm incision),and C(1.8 mm incision)comprised 30,34 and 32 eyes respectively.All cases were treated with clear corneal incision phacoemulsification combined with trabeculectomy.Data including best corrected visual acuity(BCVA),corneal astigmatism,corneal endothelial cell counts(CECC),intraocular pressure(IOP),and complications were collected before the operation,and at postoperative 1 d,1 and 3 mo.●RESULTS:All the patients were successfully treated with surgery.The BCVA of groups B and C were significantly improved as compared to group A at postoperative 1 d,1 and 3 mo(all P<0.05),but there was no difference between groups B and C at each time interval(all P>0.05).The corneal astigmatism of group A was statistically higher than that of group B(P=0.026);corneal astigmatism of group B was statistically higher than that of group C at postoperative 1 d(P=0.006).The corneal astigmatism of group A at postoperative 3 mo was significantly higher than that before operation(P=0.003).At postoperative 1 and 3 mo,corneal astigmatism of groups B and C were significantly lower than that of group A(all P<0.05).The CECC in group B was significantly higher than that of group A(P=0.020),and CECC in group C was significantly higher than that of group B(P=0.034)at postoperative 1 d.At postoperative 1 and 3 mo,CECC of groups B and C were significantly higher than that of group A(all P<0.05).In each group,postoperative mean IOP at each time interval was significantly lower than preoperative IOP(all P<0.05).●CONCLUSION:Coaxial microincision phacoemulsification combined with trabeculectomy for PACG with cataract has better curative efficacy in reducing postoperative corneal astigmatism and corneal endothelial cell injury than traditional small incision combined surgery,and the 1.8 mm microincision has better curative efficacy than 2.2 mm microincision in the early postoperative period.

文摘AIM: To report on the efficacy of combined endoscopic cyclophotocoagulation(ECP) and phacoemulsification cataract extraction(PCE) with intraocular lens placement for reduction of intraocular pressure(IOP) and medication burden in glaucoma.·METHODS: A retrospective case review of 91 eyes(73patients) with glaucoma and cataract that underwent combined PCE/ECP surgery was performed. Baseline demographic and ocular characteristics were recorded,as well as intraocular pressure, number of glaucoma medications, and visual acuity postoperatively with 12-month follow-up. Treatment failure was defined as less than 20% reduction in IOP from baseline on two consecutive visits(at 1, 3, 6, or 12 mo postoperatively),IOP ≥21 mm Hg or ≤5 mm Hg on two consecutive visits, or additional glaucoma surgery performed within12 mo after PCE/ECP.·RESULTS: Overall, mean medicated IOP was reduced from 16.65 mm Hg at baseline to 13.38 mm Hg at 12mo(P 0.0001). Mean number of glaucoma medications was reduced from 1.88 medications at baseline to 1.48 medications at 12mo(P =0.0003). At 3mo postoperatively,the success rate was 73.6%(95%CI: 63.3, 81.5), 57.1% at6mo(95% CI: 46.3, 66.6), and 49.7% at 12mo(95% CI:38.9, 59.6). Patient demographic characteristics were not associated with treatment success. The only ocular characteristic associated with treatment success was a higher baseline IOP.· CONCLUSION: Combined PCE/ECP surgery is an effective surgical option for the reduction of IOP and medication burden in glaucoma patients. Patients withhigher baseline IOP levels are most likely to benefit from this procedure.
文摘AIM: To compare the efficacy and safety of phacoemulsification(Phaco) against combined phacotrabeculectomy(Phacotrabe) in primary angle-closure glaucoma(PACG) with coexisting cataract.·METHODS: By searching electronically the Pub Med,EMBASE, Scientific Citation Index and Cochrane Library published up from inception to January 2014, all randomized controlled trials that matched the predefined criteria were included. The quality of included trials was evaluated according to the guidelines developed by the cochrane collaboration. And the outcomes estimating efficacy and safety of two different surgical treatments were measured and synthesised by Rev Man 5.0.· RESULTS: Five randomized controlled trials were selected and included in Meta-analysis with a total of468 patients(468 eyes) with both PACG and cataract. We found that Phacotrabe had a greater intraocular pressure(IOP) lowing effect [preoperative IOP: weighted mean difference(WMD)=0.58, 95% confidence intervals(95% CI,-0.53 to 1.69), P =0.31; postoperative IOP: WMD =1.37,95% CI(0.45 to 2.28), P =0.003], a lower number of antiglaucoma medications [risk ratio(RR)=0.05, 95% CI(0.02 to 0.18), P 〈0.00001] needed postoperatively and less serious damage of optic nerve [RR =0.48, 95% CI(0.21 to 1.07), P =0.07], but a higher risk of complications[odds ratio(OR)=0.04, 95% CI(0.01 to 0.16), P 〈0.00001]compared with Phaco. The rest studies indicated that there had no significantly difference between the two surgical methods for postoperative best-corrected visual acuity(BCVA) [WMD =-0.05, 95% CI(-0.14 to 0.05), P =0.32] and loss of visual field [RR=1.06, 95% CI(0.61 to1.83), P =0.83].·CONCLUSION: Phaco alone compared with Phacotrabe had a better effect in IOP reduction, whereas the securitydecline. Considering the number of sample size, our results remains to be further studied.
文摘AIM: To evaluate the therapeutic effect of pupilloplasty combined with phacomulsification and intraocular lens implantation(PPI) in uveitis-induced cataract.METHODS: Total 28 patients with uveitis-induced cataract were enrolled. Within 3 mo before the PPI, 7 cases accompanied with glaucoma maintained carteolol hydrochloride for lowering intraocular pressure, and 1 case maintained glucocorticoid for anti-inflammation. The baseline characteristics, treatment processes, and outcomes of enrolled cases were retrospectively analyzed. Hematoxylin and eosin(HE) staining was performed to reveal the histopathological changes of iris tissues.RESULTS: Iris hemorrhage was the only intraoperative complication observed in 2 cases. After the surgery, normal intraocular pressure, right position of intraocular lens, and improved visual gain [best corrected visual acuity(BCVA)>0.5] were achieved. Postoperative keratic precipitates was observed in 2 cases, which was recovered within 1 wk. During the follow-up of 5-10 y, no recurrence of uveitis was found in 27 cases(96.43%). Uveitis only recurred in one case with the onset of ankylosing spondylitis. HE staining showed iris stroma(all samples), pigment cell hyperplasia in pigment epithelium(n=9) and stroma(n=19), inflammatory cell infiltration in iris(n=7), and neovascularization in iris surface(n=2).CONCLUSION: PPI improves the visual gain and prevents the long-term recurrence of uveitis in patients with uveitis-induced cataract, including those with preoperative intraocular pressure abnormality(glaucoma) and inflammation(active uveitis). Uveitis presents stroma atrophy, pigment cell hyperplasia, and inflammatory cell infiltration, even in a quiet state.
文摘Purpose: The purpose of this study was to evaluate a new procedure aimed at lengthening the palpebral fissure to facilitate femtosecond laser-assisted cataract surgery in patients with small eyes. Method: A quick procedure using the CO2 laser was adapted for patients with small eyes undergoing laser-assisted cataract surgery using the Catalys system. The UniPulse CO2 laser (Nidek) was used for laser lateral canthotomy on patients with small palpebral fissures to allow fitting of the Liquid OpticTM Interface eyepiece. Results: Lateral canthotomies were performed on 19 women and 7 men (ages ranged from 45 to 93 years) with lower eyelid lengths equal to or shorter than 32 mm who then underwent femtosecond laser-assisted cataract surgery. A total of 33 eyelids received laser lateral canthotomy with the CO2 laser;only one eyelid had lateral canthotomy with cold-steel tenotomy scissors. Dockings were completed for all 34 eyes with eyelids receiving lateral canthotomies. The 33 eyes with eyelids that received laser canthotomy with the CO2 laser had successful femtosecond laser-assisted cataract surgery. The one eye with the eyelid that received cold-steel canthotomy could not have femtosecond laser-assisted cataract surgery despite successful docking because of pupillary constriction. The findings were statistically significant;Fisher Exact Test showed a p-value of 0.0294. Conclusion: Laser lateral canthotomy with CO2 laser is a safe and effective method to allow docking and completion of femtosecond laser-assisted cataract surgery.
文摘The authors report the results of penetrating keratoplasty combined with cataract extraction in 50 cases. The rate of transparent grafts was 62% after an average follow-up of 19 months. 60% of the patients restored their vision to 0.1 and better. The rate of transparent grafts and visual improvement did not correlate with the mode of cataract extraction; however, the extracapsular procedure had less vitreous during operation than the intracapsular modality did. The authors recommend that the combined operation be adopted for patients with corneal opacity and cataract, and preferably using the extracapsular mode.
文摘AIM: To report the long-term outcomes of combined excisional goniotomy and manual small incision cataract surgery(MSICS).METHODS: This is a retrospective case series of patients with open angle glaucoma and visually significant cataracts that underwent combined excisional goniotomy and MSICS with one-year follow-up. The medical history, demographic information, and clinical characteristics of each case were recorded. Data regarding changes in vision, intraocular pressure(IOP), the number of glaucoma medications, and the evolution of the disease after surgery were reported. RESULTS: Three patients, with open angle glaucoma and cataracts underwent combined excisional goniotomy and MSICS without adverse events. All patients had improvement in vision compared to baseline measurements. The range of IOP at baseline was from 14 to 18 mm Hg and decrease to a range of 10 to 14 mm Hg after one year of follow-up. Additionally, two patients also decreased their dependence on IOP-lowering medications at the last follow up visit with one patient maintaining baseline level of medication use.CONCLUSION: A combination of excisional goniotomy and MSICS illustrates both the safety and efficacy to treat patients with visually significant cataract and glaucoma. This procedure allows for a more cost-effective surgical approach that matches the needs of resource strained territories around the globe.
文摘Objective:To analyze the efficacy of ultrasonic emulsification and small incision cataract extracapsular extraction in cataract patients.Methods:96 cataract patients admitted from May 2021 to May 2023 were selected and randomly grouped into group A(ultrasonic emulsification)and group B(small-incision extracapsular cataract extraction),with 48 cases each.Results:At 1 week,1-month,and 3 months post-operation,the visual acuity of group A was higher and the astigmatism value was lower than that of group B(P<0.05);at 12h,24h,and 48h post-operation,the intraocular pressure of group A was higher than that of group B(P<0.05);the thickness of macular area of group A was lower than that of group B at 1 week and 1-month post-operation(P<0.05).Conclusion:Ultrasonic emulsification in cataract patients was slightly better than small incision cataract extracapsular extraction in correcting astigmatism,improving visual acuity,and regulating macular thickness.However,due to the high energy of ultrasonic emulsification,the risk of complications such as high postoperative intraocular pressure was higher.Small-incision extracapsular cataract extraction has better application value in economically disadvantaged areas.
文摘Objective: To observe the effect of oral fuming tablets on the levels of serum β2-microglobulin (β2-MG), Glycosylated hemoglobin (HbA1c), Nitric oxide (NO), Malondialdehyde (MDA) and superoxide dismutase (SOD) in patients with diabetic cataract (DC) after phacoemulsification combined with vitrectomy. Methods: A total of 90 patients with DC were randomly divided into control group (n=45) and observation group (n=45) according to the lottery method. Both groups were treated with conventional therapy. On this basis, the control group underwent phacoemulsification combined with vitrectomy. The observation group was treated with Fuming tablets on the basis of the control group. The levels of β2-MG, HbA1c, NO, MDA and SOD in peripheral blood were measured in all subjects. Result: Before treatment, there were no significant difference in serum levels of β2-MG, HbA1c, NO, MDA and SOD between the two groups. The levels of β2-MG, HbA1c, NO and MDA in the two groups after treatment were significantly lower than those before treatment. And the levels of β2-MG, HbA1c, NO and MDA of the observation group was notably lower than those of the control group. After treatment, the levels of SOD in the two groups were notably higher than those before treatment. And the levels of SOD of the observation group was notably higher than those of the control group after treatment. Conclusion: After phacoemulsification combined with vitrectomy, supplemented with Fuming tablet treatment can effectively reduce serum levels of β2-MG and HbA1c to improve the degree of fundus lesions in DC patients;reduce serum MDA and NO levels, increase the concentration of SOD, DC patients to restore the antioxidant energy. Fuming tablets are effective adjuvant drugs for clinical cataract surgery.
文摘Dear Editor,We write to introduce a case of high myopia who had bilateral macular schisis along with cataracts.During the following-up period from 2014 to 2021,the severity of macular schisis gradually worsened.However,following cataract surgery,there was a gradual improvement in the macular schisis,ultimately leading to near-complete resolution.We obtained the written informed consent from the patient,and this case study adhered to the principles in the Declaration of Helsinki.

文摘AIM:To investigate sex-based differences in the occurrence of intra-operative and post-operative complications and associated visual outcomes following cataract surgery.METHODS:This was a retrospective study of patients who had phacoemulsification cataract surgery at the University of Colorado School of Medicine.Data collected included the patient’s health history,ocular comorbidities,operative and post-operative complications,and the post-operative best corrected visual acuity(BCVA).The data were analyzed using univariate and multivariable logistic regression with generalized estimating equations to account for the correlation of some patients having two eyes included in the study.RESULTS:A total of 11977 eyes from 7253 patients were included in the study.Ocular comorbidities differed by sex,with males having significantly higher percentages of traumatic cataracts(males 0.7%vs females 0.1%),prior ocular surgery(6.7%vs 5.5%),and mature cataracts(2.8%vs 1.9%).Conversely,females had significantly higher rates of pseudoexfoliation(2.0%vs 3.2%).In unadjusted analysis,males had higher rates of posterior capsular rupture(0.8%vs 0.4%)and vitreous loss(1.0%vs 0.6%),but this difference was not significant after adjustment for confounders.Males had a significantly increased risk of post-operative retinal detachment,but in multivariable analysis this was no longer significant.Males were significantly less likely to undergo post-operative neodymium-doped yttrium aluminum garnet(Nd:YAG)laser capsulotomy for posterior capsule opacification(OR=0.8,95%CI=0.7-0.9,P=0.0005).The BCVA was slightly worse for males pre-operatively;but post-operatively,both sexes exhibited similar visual acuity of Snellen equivalent 20/25.CONCLUSION:The study finds that in a cohort of patients presenting for cataract surgery,sex differences exist in pre-operative comorbidities and surgical characteristics that contribute to higher rates of some complications for males.However,observed surgical complication rates exhibit almost no difference by sex after adjusting for pre-operative differences and post-operative BCVA is similar between sexes.
