Cataract is the main cause of visual impairment and blindness worldwide while the only effective cure for cataract is still surgery.Consecutive phacoemulsification under topical anesthesia has been the routine procedure for cataract surgery.However,patients often grumbled that they felt more painful during the second-eye surgery compared to the first-eye surgery.The intraoperative pain experience has negative influence on satisfaction and willingness for second-eye cataract surgery of patients with bilateral cataracts.Intraoperative ocular pain is a complicated process induced by the nociceptors activation in the peripheral nervous system.Immunological,neuropsychological,and pharmacological factors work together in the enhancement of intraoperative pain.Accumulating published literatures have focused on the pain enhancement during the secondeye phacoemulsification surgeries.In this review,we searched PubMed database for articles associated with pain perception differences between consecutive cataract surgeries published up to Feb.1,2024.We summarized the recent research progress in mechanisms and interventions for pain perception enhancement in consecutive secondeye phacoemulsification cataract surgeries.This review aimed to provide novel insights into strategies for improving patients’intraoperative experience in second-eye cataract surgeries. 展开更多

BACKGROUND Cataracts pose a significant clinical burden due to their complex pathogenesis.In recent years,an increase in cataracts coexisting with myopia has heightened the incidence of retinopathy and posterior vitreous detachment.Additionally,symptoms of ocular axis elongation,lens nucleus hardening,and vitreous liquefaction have become more prevalent.While conventional extracapsular cataract extraction is commonly employed,it often yields suboptimal visual outcomes.Subsequent advancements in cataract phacoemulsification and lens implantation surgeries have gained widespread acceptance for their ability to improve refraction and significantly improve uncorrected visual acuity.AIM To investigate the effect of capsular treatment after phacoemulsification lens implantation in myopic patients with cataract.METHODS We selected 110 patients(with 134 eyes)with myopia and cataracts treated.These patients were categorized into two groups:an observation group(57 patients with 70 eyes)and a control group(53 patients with 64 eyes).The control group underwent cataract phacoemulsification and lens implantation,while the observation group received a refined capsular treatment based on the control group’s procedure.We assessed the differences in visual acuity and quality between the two groups before and after surgery.RESULTS At six months post-operation,the observation group exhibited significantly improved far vision,intermediate vision,near vision,lower objective scattering index,higher Modulation transfer function cut-off frequency,and overall vision metrics at different contrast levels(100%,20%and 9%)compared to the control group(P<0.05).The total score of the National Eye Institute Visual Function Questionnaire in the observation group at 6 months after operation was significantly higher than that in the control group(P<0.05).No significant difference in the incidence of adverse reactions was observed between the observation group and control group(P>0.05).CONCLUSION Capsular treatment demonstrates efficacy in improving visual acuity and quality after phacoemulsification lens implantation in myopic patients with cataracts,warranting its clinical application. 展开更多

BACKGROUND Diabetic patients with cataracts encounter specific difficulties during cataract surgery due to alterations in microcirculation,blood supply,metabolism,and the microenvironment.Traditional phacoemulsification may not fully tackle these issues,especially in instances with substantial preoperative astigmatism.The utilization of femtosecond laser-assisted phacoemulsification,in conjunction with Toric intraocular lens(IOL)implantation,offers a potentially more efficient strategy.This research seeks to evaluate the efficacy and possible complications of this approach in diabetic cataract patients.AIM To investigate the clinical efficacy and complications of femtosecond laser-assisted phacoemulsification combined with Toric IOL implantation in diabetic cataract patients,comparing it with traditional phacoemulsification methods.METHODS This retrospective study enrolled 120 patients with diabetes cataract from May 2019 to May 2021.The patients were divided into two groups:the control group underwent traditional phacoemulsification and Toric IOL implantation,while the treatment group received Len Sx femtosecond laser-assisted treatment.Outcome measures included naked eye vision,astigmatism,high-level ocular phase difference detection,clinical efficacy,and complication.RESULTS There were no significant preoperative differences in astigmatism or naked eyesight between the two groups.However,postoperative improvements were observed in both groups,with the treatment group showing greater enhancements in naked eye vision and astigmatism six months after the procedure.High-level corneal phase difference tests also indicated significant differences in favor of the treatment group.CONCLUSION This study suggests that femtosecond laser-assisted phacoemulsification combined with Toric IOL implantation appears to be more effective in enhancing postoperative vision in diabetic cataract patients compared to traditional methods offering valuable insights for clinical practice. 展开更多

Background: Goniosynechialysis is a surgical procedure that has been shown to slow the progression of glaucoma in oriental eyes with chronic angle closure glaucoma. This procedure was successful in 80% of cases, and the peripheral anterior syenchiae did not exist until one year later. Nonetheless, there is little evidence of its efficacy in our context. Our study aims to investigate the efficacy of goniosynechialysis during phacoemulsification in patients with primary angle closure disease and concomitant cataract. Methods: This was an observational, prospective study. The intra-ocular pressure, need for anti-glaucoma drugs, visual acuity, the extent of synechiae, anterior chamber depth, surgical success rate, and other indicators were monitored for at least three months following surgery. Results: This study included 114 patients (118 eyes), 61 with chronic angle closure glaucoma (51.69%), 33 with primary angle closure (27.97%), and 24 with acute attack angle closure (20.34%), who were surgically treated with phacoemulsification and goniosynechialysis (Phaco-GSL). The mean intra-ocular pressure had significantly decreased three months after surgery (pre- vs post-op: 22.04 ± 10.86 vs 15.41 ± 6.06 mmHg, p-value p-value p-value p-value p-value Conclusion: Regardless of the type of glaucoma, combined phacoemulsification-goniosynechialysis is effective in lowering pressure, restoring vision, reducing the need for anti-glaucoma drugs, and preventing the synechial recurrence. Success was higher in eyes with less extensive synechiae. Phaco-GSL is safe and effective in the treatment of primary angle closure diseases with co-existing cataract. 展开更多

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. 展开更多

AIM: To compare the complication rate of femtosecond laser-assisted cataract surgery(FLACS) and traditional phacoemulsification for the first 18 mo of FLACS use at a private surgical center in Hawaii.METHODS: A retrospective chart review was conducted from January 2012 to June 2013. The first 273 consecutive eyes receiving FLACS and 553 eyes receiving traditional phacoemulsification were examined.All surgeries were performed at a single surgical center in Hawaii. The presence of intraoperative complications was used as the main outcome measure. Approval was obtained from the institutional review board of the University of Hawaii.RESULTS: The overall complication rate for FLACS was 1.8%, while that of the traditional procedure was5.8%(P 【0.05). A majority of the surgeons(80%) had a lower complication rate while using FLACS.CONCLUSION: FLACS is comparable in safety, if not safer, than traditional cataract surgery when performed by qualified cataract surgeons on carefully selected patients. 展开更多

AIM: To evaluate blood pressure(BP) changes during phacoemulsification(PC) and femtosecond laser(FSL)-assisted cataract surgery.METHODS: A retrospective chart review was performed for all patients who received traditional phacoemulsification surgery(PC group) and FSL-assisted cataract surgery(FS group) from July 2013 to December 2014. Totally 206 eyes from 133 patients receiving the two types of procedures were included.Patient characteristics(age, gender, and hypertension history), pre- and post-operative BPs were collected.RESULTS: The pro-operative systolic and diastolic BPs(mm Hg) were 124.89 ±20.48 vs 126.98 ±16.85, and71.88 ±9.81 vs 73.56 ±10.03, in PC and FS groups,respectively. While the post-operative systolic and diastolic BPs(mm Hg) were 130.13 ±22.59 vs 134.77 ±17.52, and 73.41 ±11.62 vs 78.89 ±12.2, in PC and FS groups, respectively. Paired-sample t-tests showed obvious systolic and diastolic BP elevations in FS group after surgery(P =0.001 and 0.007) and no reliability in PC group(P =0.094 and 0.359). A linear regression model revealed systolic and diastolic BP elevations,which were related to longer surgical times for FS group(P =0.008 and 0.021). Age, gender, and hypertension history were not correlated with blood pressure elevation in either group.CONCLUSION: BP increases but at a limited level after FSL-assisted cataract surgery compared to traditional phacoemulsification 展开更多

AIM: To update and investigate the clinical outcomes and complications between femtosecond laser-assisted cataract surgery(FLACS) and conventional phacoemulsification cataract surgery(CPCS). METHODS: A Meta-analysis was performed using databases, including Pubmed, Embase, and the Cochrane library. At least one of the clinical outcomes and/or complications data in each included randomized controlled trials(RCT) was reported. The quality of the RCT was assessed with the Cochrane risk assessments tool.RESULTS: Overall, 25 RCTs including 3781 eyes were included. No statistically significant difference detected between FLACS and CPCS in terms of corrected distant visual acuity(CDVA), uncorrected distant visual acuity(UDVA), and central corneal thickness(CCT) at the longterm follow up, although FLACS showed better CDVA at 1 wk postoperatively, and less increase in CCT at 1 d and 1 wk. FLACS had better postoperative endothelial cell count(ECC) at 1 and 4-6 wk, while there was no significantly difference between FLACS and CPCS at 1 d, 3 and 6 mo [weighted mean difference(WMD): 51.54, 95% confidence interval(CI):-5.46 to 108.54, P=0.08;WMD: 48.52, 95%CI:-17.54 to 114.58, P=0.15;WMD: 12.17, 95%CI:-48.61 to 72.94, P=0.69, respectively]. Postoperative endothelial cell loss(ECL) of the FLACS was significantly lower than that of the CPCS at 1, 4-6 wk, and 3 mo(P=0.02, 0.008, 0.03, respectively). However, there was no significant difference between two groups at 6 mo(WMD:-30.36, 95%CI:-78.84 to 18.12, P=0.22). No significant difference was discovered with respect to the macular edema [odds ratio(OR): 0.93, 95%CI: 0.42 to 2.05, P=0.85], capsular complication excluding posterior capsular tears(OR: 0.79, 95%CI: 0.42 to 1.50, P=0.47) and intraocular pressure change(OR: 0.82, 95%CI: 0.39 to 1.72, P=0.60). However, posterior capsular tears were more common in CPCS group(OR: 0.12, 95%CI: 0.01 to 0.98, P=0.05). The effective phacoemulsification times were significantly lower in the FLACS group compared to the CPCS group(WMD:-0.78, 95%CI:-1.23 to-0.34, P=0.0006).CONCLUSION: No statistically significant difference is discovered between FLACS and CPCS in clinical outcomes at the long-term follow up. However, higher rate of posterior capsular tears is detected in patients receiving CPCS. 展开更多

AIMTo compare the safety and efficacy of phacoemulsification and small incision cataract surgery (SICS) in patients with uveitic cataract.METHODSIn a prospective, randomized multi-centric study, consecutive patients with uveitic cataract were randomized to receive phacoemulsification or manual SICS by either of two surgeons well versed with both the techniques. A minimum inflammation free period of 3mo (defined as less than 5 cells per high power field in anterior chamber) was a pre-requisite for eligibility for surgery. Superior scleral tunnel incisions were used for both techniques. Improvement in visual acuity post-operatively was the primary outcome measure and the rate of post-operative complications and surgical time were secondary outcome measures, respectively. Means of groups were compared using t-tests. One way analysis of variance (ANOVA) was used when there were more than two groups. Chi-square tests were used for proportions. Kaplan Meyer survival analysis was done and means for survival time was estimated at 95% confidence interval (CI). A P value of &#x0003c;0.05 was considered statistically significant.RESULTSOne hundred and twenty-six of 139 patients (90.6%) completed the 6-month follow-up. Seven patients were lost in follow up and another six excluded due to either follow-up less than six months (n=1) or inability implant an intraocular lens (IOL) because of insufficient capsular support following posterior capsule rupture (n=5). There was significant improvement in vision after both the procedures (paired t-test; P&#x0003c;0.001). On first postoperative day, uncorrected distance visual acuity (UDVA) was 20/63 or better in 31 (47%) patients in Phaco group and 26 (43.3%) patients in SICS group (P=0.384). The mean surgically induced astigmatism (SIA) was 0.86&#x000b1;0.34 dioptres (D) in the phacoemulsification group and 1.16&#x000b1;0.28 D in SICS group. The difference between the groups was significant (t-test, P=0.002). At 6mo, corrected distance visual acuity (CDVA) was 20/60 or better in 60 (90.9%) patients in Phaco group and 53 (88.3%) in the manual SICS group (P=0.478). The mean surgical time was significantly shorter in the manual SICS group (10.8&#x000b1;2.9 versus 13.2&#x000b1;2.6min) (P&#x0003c;0.001). Oral prednisolone, 1 mg/kg body weight was given 7d prior to surgery, continued post-operatively and tapered according to the inflammatory response over 4-6wk in patients with previously documented macular edema, recurrent uveitis, chronic anterior uveitis and intermediate uveitis. Rate of complications like macular edema (Chi-square, P=0.459), persistent uveitis (Chi-square, P=0.289) and posterior capsule opacification (Chi-square, P=0.474) were comparable between both the groups.CONCLUSIONManual SICS and phacoemulsification do not differ significantly in complication rates and final CDVA outcomes. However, manual SICS is significantly faster. It may be the preferred technique in settings where surgical volume is high and access to phacoemulsification is limited, such as in eye camps. It may also be the appropriate technique for uveitic cataract under such circumstances. 展开更多

This study evaluated the safety of a modified method to implant an intraocular lens (IOL) into the capsular bag immediately after capsulorhexis with a whole or partial nucleus to protect the posterior capsule (PC) during phacoemulsification in a series of 12 Morgagnian cataracts. For 3 cases of hypermature cataracts with smaller and rigid nuclei, after a complete capsulorhexis, an IOL was directly inserted into the capsular bag, which protected the PC during the subsequent phacoemulsification process in the iris plate. For the other 9 cases with larger and softer nuclei, after the nucleus was partially emulsified, the IOL was inserted into the bag. Even with an obvious surge for some cases, the surgeries were uneventful in all 12 cases, with no PC rent or vitreous loss. IOL implantation into the capsular bag with a whole or partial nucleus can provide effective protection for the PC for hypermature cataract during phacoemulsification. 展开更多

AIM:To assess the early surgical outcomes of quickchop phacoemulsification technique in patients with high myopia.METHODS:The data of patients with high myopia who underwent quick-chop phacoemulsification were reviewed retrospectively. There were 42 eyes of 31 patients. The axial length was more than 26 mm in all eyes. All eyes underwent quick-chop phacoemulsification surgery with the placement of an intraocular lens(IOL) in the capsular bag. Postoperative visits were performed at 1, 3d; 2wk,1mo. Early postoperative best corrected visual acuity(BCVA), preoperative and postoperative corneal endothelial cell density(ECD), central corneal thickness(CCT) and postoperative complications were assessed.Paired sample t-test or Wilcoxon tests were used to compare data between preoperative and postoperative data.· RESULTS:There was no statistically significant difference between preoperative and postoperative ECD and CCT. Retinal detachment was developed in one eye at postoperative first day. There was an iris prolapsus from side port insicion.· CONCLUSION:Quick-chop phacoemulsification technique is a safe surgical technique. However we can encounter some complications in high myopic eyes due to histopathological differences. Both side port and clear corneal tunnel insicion size is crucial for preventing postoperative complications. If any persistent leakage is noticed, suture should be placed. 展开更多

AIM:To assess the changes in the peripapillary vasculature and macular thickness after cataract surgery using two phacoemulsification systems with optical coherence tomography angiography(OCTA).METHODS:Fifty-two eyes of 52 patients with agerelated cataract were randomized into two groups for phacoemulsification:Infiniti group(26 patients)using the Infiniti phacoemulsification system with gravity-fluidics and Centurion group(26 patients)using the Centurion phacoemulsification system with active-fluidics.The peripapillary vessel density(PVD)and macular thickness were examined using OCTA at baseline and at 1d,1 and 3mo after cataract surgery.RESULTS:In the Infiniti group,the PVD was significantly reduced at 1d after the cataract surgery(P<0.001).However,the retinal nerve fiber layer(RNFL)thickness showed no significant change during the follow-up.Change in PVD 1d postoperatively was significantly negatively correlated to the cumulative dissipated energy(CDE),estimated fluid usage(EFU),effective phacoemulsification time(EPT),intraocular pressure(IOP),and total operating time(TOT;P<0.05).The macular thickness was significantly increased in all regions after the cataract surgery(P<0.05).However,no significant changes were found in the macular vessel density(VD)during the follow-up(P>0.05).In the Centurion group,the VD and thickness in the optic papilla and macula did not significantly change in all regions during the follow-up(all P>0.05).The best-corrected visual acuity(BCVA)significantly improved in both groups postoperatively(P<0.001).CONCLUSION:Using the Infiniti phacoemulsification system,OCTA provides a promising analysis of retinal vascular alterations,demonstrating a reduction of the PVD and an increase in the macular thickness.The Centurion phacoemulsification system can provide better retinal vasculature preservation during cataract surgery. 展开更多
