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

METHODS: This prospective, comparative, observational study recruited patients into two groups. Group 1 was the control group including normal subjects except those with cataracts (cataract group, n=67 eyes of 67 patients), and group 2 was NTG group including patients who were diagnosed with NTG and cataracts (n=43 eyes of 43 patients), which were treated with phacoemulsification and intraocular lens implantation. Before surgery, and at postoperative 1 and 6too, anterior chamber angles were evaluated by SS-OCT under dark conditions using three- dimensional angle analysis scan protocol. Angle opening distance (AOD), angle recess area (ARA), and trabecular- iris surface area (TISA) at four quadrants (temporal, nasal, superior, and inferior) were calculated automatically by SS-OGT, after the observer marked scleral spurs. RESULTS: A total of 106 patients (54 males and 52 females) were enrolled in the study. Angle parameters, AOD, ARA, and TISA were increased after surgery in both groups. However, changes of angle parameters were only significant in group 2. In group 2, preoperative lOP was 13.2+2.9 mm Hg, and postoperative lOP at 1 and 6mo were 10.5+3.0 and 10.7+2.8 mm Hg, respectively. In group 1, preoperative lOP was 12.42.8 mm Hg, and postoperative lOP at 1 and 6mo were 11.6+2.5 and 12.0+2.8 mm Hg, respectively. After cataract surgery, angle parameters changed significantly while IOP significantly reduced and was maintained in group 2 (P〈0.001). The changes in angle parameters (&AOD500, ATISAS00 at temporal; &AOD500, S, RA500 at nasal) were linearly correlated with postoperative IOP changes. CONCLUSION: Cataract surgery may have improved antedor chamber angle parameters and decreased lOP in NTG patients.展开更多

Japanese sources were used for patients’ characteristics, clinical data, utility, and costs whenever available. Non-Japanese data were validated by Japanese clinical experts. RESULTS: In the probabilistic base case analysis, iStent inject;with cataract surgery was found to be cost-effective compared with cataract surgery alone over a lifetime horizon when using the ¥5 000 000/quality-adjusted life year(QALY)willingness-to-pay threshold. The incremental cost-utility ratio(ICUR) was estimated to be ¥1 430 647/QALY gained and the incremental cost-utility ratio(ICER) was estimated to be ¥12 845 154/blind eye avoided. iStent inject;with cataract surgery vs cataract surgery alone was found to increase costs(¥1 025 785 vs ¥933 759, respectively) but was more effective in increasing QALYs(12.80 vs 12.74) and avoiding blinded eyes(0.133 vs 0.141). The differences in costs were mainly driven by costs of primary surgery(¥279 903 vs ¥121 349). In the scenario analysis from a societal perspective, which included caregiver burden, iStent inject;with cataract surgery was found to dominate cataract surgery alone.CONCLUSION: The iStent inject;with cataract surgery is a cost-effective strategy over cataract surgery alone from the public payer’s perspective and cost-saving from the societal perspective in patients with mild-to-moderate POAG in Japan.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: Medical records of 62 patients (101 eyes) that underwent cataract surgery younger than 15 years of age, without history of ocular trauma and with a minimum follow-up period of 6 months, were reviewed retrospectively. Results: The most common initial complaint was leukocoria. Thirty-nine patients (62.9%) had bilateral cataracts and 23 patients (37.1%) had unilateral cataracts. The most common type was posterior polar cataract (22%) in patients with unilateral cataracts, and total cataract (33%) in patients with bilateral cataracts. The overall prevalence of postoperative complications was 58%, visual axis opacification (VAO) being the most common one (39%). The incidence of VAO was significantly higher in eyes with intact posterior capsules. Secondary glaucoma occurred in 12 (12%) eyes. Thirty-one (50%) patients were orthophoria, 17 (27%) patients had esotropia, and 14 (23%) patients had exotropia. Additional surgery for all of these complications was performed in 53 (53%) eyes. Conclusions: Despite appropriate surgical treatment of nontraumatic pediatric cataracts, post-surgical complications including VAO, glaucoma, or strabismus remain an important cause of morbidity in these patients. Posterior capsulotomy and anterior vitrectomy must be performed in all children below 6 years to reduce the need for additional surgery for VAO.展开更多

文摘AIM:To compare the clinical efficacy and safety of non-penetrating glaucoma surgery(NPGS)plus phacoemulsification(Phaco-NPGS)and NPGS-alone.METHODS:We systematically searched various databases and reviewed studies that had evaluated the effects of Phaco-NPGS or NPGS-alone for patients with glaucoma.Primary outcomes included postoperative intraocular pressure(IOP)and the number of postoperative antiglaucoma medications.Secondary outcomes were the prevalence of complications,incidence of needling or goniopuncture,and surgical success rate.RESULTS:In total,380 and 424 eyes in NPGS-alone and Phaco-NPGS groups respectively were included.Both postoperative IOP and number of medications were significantly lowered in the Phaco-NPGS group than that in the NPDS-alone group[weighted mean difference(WMD)=-1.12,95%confidence interval(CI):-2.11 to-0.12,P=0.03;WMD=-0.31,95%CI:-0.53 to-0.09,P=0.006].Moreover,Phaco-NPGS had a significantly lower prevalence of complications and postoperative procedures compared to NPGS-alone,while no significant difference existed for surgical success.CONCLUSION:Phaco-NPGS superior to NPGS-alone in the reduction of IOP and medications.Phaco-NPGS can be recommended for glaucoma patients with coexisting cataracts owing to its superior efficacy,fewer complications,and postoperative procedures.
文摘AIM:To compare the effect of phacoemulsification on intraocular pressure(IOP)in patients with primary open angle glaucoma(POAG)and pseudoexfoliation glaucoma(PXG).METHODS:A retrospective comparative case series conducted at the Glaucoma Department at the Association to Prevent Blindness in Mexico.The study enrolled consecutive patients having phacoemulsification with intraocular lens(IOL)implantation and a diagnosis of POAG or PXG.Data about IOP values and number of glaucoma medications used was collected at baseline,1,3,6 and12mo postoperatively.RESULTS:The study enrolled 88 patients(88 eyes).After phacoemulsification,there was a statistically significant reduction in IOP values and glaucoma medications use compared to baseline in both POAG and PXG patients(P〈0.001).In the POAG group,a 20%decrease in IOP values was evidenced,and a 56.5%reduction in the number of medications used at the one-year follow-up.The PXG group showed a 20.39%,and a 34.46%decrease in IOP and number of medications used,respectively.A significant difference in the meanΔIOP(postoperative changes in IOP)was evidenced between groups(P=0.005).The reduction of the postsurgical IOP mean values in both groups,the POAG group showed a greater reduction in IOP values compared to the PXG group.CONCLUSION:In both types of glaucoma,phacoemulsification cataract surgery can result in a significant IOP reduction(20%)over a 12mo follow-up period.The number of medications used is also significantly reduced up to 12mo after surgery,especially in the PXG group.
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 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AIM:To evaluate the postoperative refractive prediction error(PE)and determine the factors that af fect the refractive outcomes of combined pars plana vitrectomy(PPV)or silicone oil removal(SOR)with cataract surgery.METHODS:The study is a retrospective,case-series study.Totally 301 eyes of 301 patients undergoing combined PPV/SOR with cataract surgery were enrolled.Eligible individuals were separated into four groups according to their preoperative diagnoses:silicone oil-filled eyes after PPV(group 1),epiretinal membrane(group 2),macular hole(group 3),and primary retinal detachment(RD;group 4).The variables af fecting postoperative refractive outcomes were analyzed,including age,gender,preoperative best-corrected visual acuity(BCVA),axial length(AL),keratometry average,anterior chamber depth(ACD),intraocular tamponade,and vitreoretinal pathology.The outcome measurements include the mean refractive PE and the proportions of eyes with a PE within±0.50 diopter(D)and±1.00 D.RESULTS:For all patients,the mean PE was-0.04±1.17 D,and 50.17%of patients(eyes)had a PE within±0.50 D.There was a significant difference in refractive outcomes among the four groups(P=0.028),with RD(group 4)showing the least favorable refractive outcome.In multivariate regression analysis,only AL,vitreoretinal pathology,and ACD were strongly associated with PE(all P<0.01).Univariate analysis revealed that longer eyes(AL>26 mm)and a deeper ACD were correlated with hyperopic PE,and shorter eyes(AL<26 mm)and a shallower ACD were correlated with myopic PE.CONCLUSION:RD patients have the least favorable refractive outcome.AL,vitreoretinal pathology,and ACD are strongly associated with PE in the combined surgery.These three factors affect refractive outcomes and thus can be used to predict a better postoperative refractive outcome in clinical practice.
文摘Purpose: To evaluate post-surgical complications in patients who were operated for nontraumatic pediatric cataracts in our clinic. Methods: Medical records of 62 patients (101 eyes) that underwent cataract surgery younger than 15 years of age, without history of ocular trauma and with a minimum follow-up period of 6 months, were reviewed retrospectively. Results: The most common initial complaint was leukocoria. Thirty-nine patients (62.9%) had bilateral cataracts and 23 patients (37.1%) had unilateral cataracts. The most common type was posterior polar cataract (22%) in patients with unilateral cataracts, and total cataract (33%) in patients with bilateral cataracts. The overall prevalence of postoperative complications was 58%, visual axis opacification (VAO) being the most common one (39%). The incidence of VAO was significantly higher in eyes with intact posterior capsules. Secondary glaucoma occurred in 12 (12%) eyes. Thirty-one (50%) patients were orthophoria, 17 (27%) patients had esotropia, and 14 (23%) patients had exotropia. Additional surgery for all of these complications was performed in 53 (53%) eyes. Conclusions: Despite appropriate surgical treatment of nontraumatic pediatric cataracts, post-surgical complications including VAO, glaucoma, or strabismus remain an important cause of morbidity in these patients. Posterior capsulotomy and anterior vitrectomy must be performed in all children below 6 years to reduce the need for additional surgery for VAO.

文摘BACKGROUND Asymmetric multifocal intraocular lenses(IOLs)are now widely used in the modern cataract surgery,providing a good level of visual performance over a range of distances and high postoperative patient satisfaction.We report a case of improved visual quality after shifting the near segment of an asymmetrical multifocal IOL to the superotemporal placement in the dominant eye of a glaucoma patient.CASE SUMMARY A 72-year-old woman with bilateral glaucoma underwent phacoemulsification in the dominant eye(left eye)with implantation of an asymmetrical multifocal IOL.Postoperative uncorrected distance visual acuity(UDVA)was 0.0 logMAR(20/20 Snellen)and uncorrected near visual acuity(UNVA)was 0.1 logMAR(20/25 Snellen).Two weeks later,the patient presented to our clinic with decreased vision due to migration of lens epithelial cells to IOL anterior surface and edema of corneal endothelial cells.Anterior capsule polishing and superotemporal placement of near segment[+3.00 diopter(D)addition(add)]of IOL were performed.As a result,UDVA at the first week and first year after reposition was 0.0 logMAR(20/20 Snellen),and compared with 0.3 logMAR(20/40 Snellen)in the first week,the UNVA was improved to 0.0 logMAR(20/20 Snellen)one year after surgery.CONCLUSION The postoperative inflammatory reaction and lens epithelial cells proliferation were obvious in this glaucoma patient.Capsule polishing and rotation of the lens were beneficial to the patient,which not only enhanced the patient's vision,but also improved the patient's satisfaction.Therefore,glaucoma patients need to be cautious of implanting multifocal IOLs.Placement of a near segment of an asymmetrical multifocal IOL in the dominant eye should be performed on an individual basis.
