Abstract
Traumatic posterior chamber intraocular lens (PC-IOL) extrusion via a self-sealing scleral tunnel, created for manual small-incision cataract surgery (MSICS), is a rare occurrence that has never been reported before. Usually, the PC-IOL protrudes through a ruptured cornea or falls back into the vitreous after blunt trauma. Here, we present a case of PC-IOL extrusion along the uveal tissue through the scleral tunnel in an 80-year-old woman with a history of MSICS who fell and hit her right eye on the stairs, resulting in sudden and painful loss of vision in the same eye. The IOL, along with necrotic uveal tissue, was removed from the subconjunctival space, and the ruptured scleral tunnel was sutured. After initial management, her best-corrected visual acuity (BCVA) was 6/36 with aphakic spectacle correction. The patient was advised to undergo secondary scleral fixation of the intraocular lens. The scleral tunnel made in MSICS is a potentially weak area, and the PC-IOL can come out through it. Therefore, suturing the scleral tunnel with a non-absorbable nylon 10-0 suture should be considered during MSICS. This provides additional support to the weakened scleral wall.

Abstract
PURPOSE The aim of the study was to assess the spectrum of clinical presentation, intraoperative challenges and immediate surgical outcome of cataract patients with pseudoexfoliation syndrome (PXF) following manual small incision cataract surgery (MSICS). METHODS This prospective observational study which was conducted in a rural tertiary care hospital included adult patients with cataract and associated PXF. MSICS was performed for all after a complete ophthalmic and systemic examination. Clinical profile, intraoperative and post-operative complications were noted. Uncorrected visual acuity on first day post-surgery was used to assess the surgical outcome following MSICS. RESULTS MSICS was performed in 80 eyes with varying grades of cataract and PXF. The mean age of the patients was 62.5 ± 8.9 years. PXF material on pupillary margin in 77(96%) patients was the most common finding noted. Majority of the patients had advanced cataract (72, 90%) and inadequate mydriasis (62, 77.5%). Posterior capsular rent (8, 10%) and zonular dehiscence (8, 10%) were the intraoperative difficulties faced. Uncorrected visual outcome on first post-operative day was moderate to good in 71 (88.8%) patients, limited by post-operative corneal oedema (21, 26.3%), iritis (31, 38.8%) and aphakia (9, 11.3%). CONCLUSION Patients with pseudoexfoliation had poor pupillary dilatation, advanced cataracts and higher rate of posterior capsular rent. Our study showed good outcome of MSICS in PXF patients, even with advanced cataract suggesting that MSICS is a safe, effective and viable option for patients with PXF and cataract.

Kamonporn N, Pipat K. The visual outcomes and complications of manual small incision cataract surgery and phacoemulsification: long term results. Rom J Ophthalmol 2021; 65:31-37. [PMID: 33817431 PMCID: PMC7995515 DOI: 10.22336/rjo.2021.7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022] Open
Abstract
Objective: To compare visual outcomes and complications between manual small incision cataract surgery (MSICS) and phacoemulsification. Methods: A retrospective study was conducted in the tertiary care center. A total of 1281 cases underwent manual small incision cataract surgery and phacoemulsification from January 2014 to December 2016. The postoperative best corrected visual acuity (BCVA) along with the rates of complications were compared between both groups. Results: Five hundred and twenty-one patients (40.67%) and 760 patients (59.33%) were subjected by staff members and residents, respectively. Altogether, 689 cases (53.79%) were subjected to MSICS technique and 592 cases (46.21%) to phacoemulsification. The MSICS group had significantly harder cataract (cataract grading ≥ 4+ :31.64% vs. 7.77%; p<0.001). One month postoperatively, good visual outcome (BCVA ≥ 6 /18) in the phacoemulsification group was higher than that in the MSICS group (86.33% vs. 72.12%, p<0.001). The risk factor for poor outcome (post-operative BCVA < 6 /60 in both groups) was the presence of associated ocular pathologies. The intraoperative and perioperative complications rates were higher in the MSICS group (16.55% vs. 6.6%, p<0.001). The most common complications were hyphema (4.35%), posterior capsule ruptures (4.21%), and prolapsed iris (3.05%). Long-term postoperative complication rates were higher in the phacoemulsification group (9.29% vs. 21.28%, p<0.001). The most common complication was posterior capsule opacity (8.71% vs. 20.44%, p<0.001). Pseudophakic bullous keratopathy (PBK) was similar in both groups (0.29% vs. 0.17%, p=1.00). Conclusion: The number of patients who had experienced good visual outcomes was higher in the phacoemulsification group. However, for both groups, no significant differences were found on the long-term complication rate.

Abstract
PURPOSE To determine the clinical outcomes and causes of late presentation in lens induced glaucoma (LIG). DESIGN Prospective observational study. PARTICIPANTS One hundred sixty-five patients with LIG who underwent cataract surgery. METHODS Preoperative data collection included a questionnaire about reasons for late presentation, socioeconomic status, visual acuity, intraocular pressure (IOP), and the lens and angle status of the fellow eye. All patients underwent manual small-incision cataract surgery. Postoperative vision, IOP, the anterior segment, and the fundus were evaluated at days 1, 15, and 30. MAIN OUTCOME MEASURES Reasons for late presentation, status of the fellow eyes, and surgical outcomes, including visual acuity and IOP at the 1-month postoperative visit. RESULTS Mean age at presentation was 63.8 years, and the female-to-male ratio was 1.4:1. Of the entire cohort, 70.3% were phacolytic and 29.7% had phacomorphic glaucoma. The main causes for late presentation was nonfinancial (81.2%); of these, good vision in fellow eye and lack of escort to the hospital were the major reasons. Most fellow eyes were pseudophakic (72.1%). After surgery, 75.6% gained best-corrected visual acuity of 6/18 or more. Six percent experienced poor visual recovery (≤6/60) with optic atrophy as the major cause. Only 7.9% required further glaucoma management in the form of topical medications. Delayed presentation (>15 days) was associated with poor visual outcome. CONCLUSIONS Nonfinancial causes, including good vision in the fellow eye and lack of escort, were the major determinants of late presentation. Most patients were pseudophakic in the fellow eye. After cataract extraction, only a few LIG patients required further glaucoma management.

Abstract
Purpose: To present the technique and outcomes of a modified manual small incision cataract surgery designed for the phacoemulsification surgeons who are learning to perform manual small incision cataract surgery. Methods: This was a retrospective, single-centred, comparative study. We included all the patients who underwent the modified manual small incision cataract surgery for visually significant cataract at Singapore National Eye Centre. All surgeries were performed by either a senior phaco-trained surgeon (M.A.) who had performed more than 500 manual small incision cataract surgery or a junior phaco-trained surgeon (D.C.) who had performed around 500 phacoemulsification but never performed any manual small incision cataract surgery. The main modification of this technique lies in the creation of an additional phaco-like main wound at 90° to the scleral tunnel wound, with most surgical steps performed through this additional wound. The outcomes were analysed and compared between the senior and junior surgeons. The main outcome measures were visual outcome and major intraoperative complications such as posterior capsular rupture and zonular dialysis. Results: A total of 132 cases were included; 102 (77.3%) and 30 (22.7%) cases were performed by the senior and junior surgeons, respectively. Pre-operatively, 85.6% eyes had best-corrected visual acuity of counting fingers or worse. Postoperatively, the visual outcome at 1 month was similar between the senior and junior surgeons, with 68.7% eyes achieving a best-corrected visual acuity of ⩾6/12 (p = 0.17). No posterior capsular rupture, zonular dialysis or endophthalmitis was observed during the study period. Conclusions: This modified technique may serve as a useful transition technique for the phaco-trained surgeons to develop skills in manual small incision cataract surgery, with demonstrable good visual outcome and safety.

Abstract
PURPOSE To analyze the effectiveness of intracameral moxifloxacin prophylaxis in reducing acute postoperative endophthalmitis after trabeculectomy and combined trabeculectomy plus cataract extraction. DESIGN Retrospective clinical registry analysis. PARTICIPANTS Patients undergoing either trabeculectomy or trabeculectomy plus cataract extraction at Aravind Eye Hospitals (AEH) between 2009 and 2018 (inclusive). METHODS Electronic health records data were analyzed before and after implementation of routine intracameral moxifloxacin, and acute postoperative endophthalmitis rates were compared. During 2015, routine intracameral moxifloxacin prophylaxis was added in a step-wise fashion throughout AEH. Date of implementation was used to create group 1 (without intracameral moxifloxacin prophylaxis) and group 2 (with intracameral moxifloxacin prophylaxis). MAIN OUTCOME MEASURES The primary outcome was the difference in acute (≤6 weeks) postoperative endophthalmitis between groups 1 and 2. Review of culture results, visual acuity, and intraocular pressure also was performed for patients with endophthalmitis. RESULTS Thirty-eight thousand nine hundred eyes (group 1) did not receive intracameral moxifloxacin, whereas 19 086 eyes (group 2) did. Although the rate of noninfectious postoperative complications was not significantly different (0.81% vs. 0.67%; P = 0.07), a significantly lower rate of acute postoperative endophthalmitis was found in group 2 versus group 1 (0.03% vs. 0.08%; P = 0.03). Patients receiving intracameral moxifloxacin showed approximately 2.5-times lower odds of infection (odds ratio, 0.39 for group 2 vs. group 1; 95% confidence interval, 0.16-0.95) and almost 4-times lower odds after adjustment for covariates (odds ratio, 0.26 for group 2 vs. group 1; 95% confidence interval, 0.09-0.74). The rate of early postoperative infection after intracameral moxifloxacin introduction was lower for patients undergoing both trabeculectomy alone (0.09%-0.03%; P = 0.27) and combined trabeculectomy plus cataract extraction (0.08%-0.03%; P = 0.06). Although most cultures yielded no growth, no Staphylococcus or gram-negative growth was found for patients in group 2, who received intracameral moxifloxacin. CONCLUSIONS Intracameral moxifloxacin prophylaxis was associated with a nearly 4-fold lower rate of early postoperative endophthalmitis in patients undergoing trabeculectomy or combined trabeculectomy plus cataract extraction.

Abstract
Ocular inflammation resulting from a lens pathology is rare in the absence of a cataract or lens trauma because of the lens' immune privilege. The lens can be a source of ocular inflammation when the capsule is broken or when lens proteins leak out through an intact capsule. These uveitides are termed lens-induced uveitis (LIU) and are often associated with advanced cataracts. Cataracts are part of the normal aging process, and in today's world, cataract surgery is a safe and affordable means of vision restoration in the developed world. In patients with neglected cataracts and in the developing world where cataract surgery rates are lower, LIU rates are higher together with the associated complications. In this literature review, we intend to equip the armamentarium of the practicing ophthalmologist with an updated knowledge on the demographic features, clinical characteristics, treatment options, and outcomes of LIU. This is to highlight the need for timely management of cataracts before the development of advanced cataracts and LIU.

Abstract
Purpose To evaluate various methods of nucleus delivery in manual small incision cataract surgery, with reference to visual outcome, intraoperative, and postoperative complications. Methods In this prospective randomized interventional study, five groups of 40 cases each were constituted, with reference to nucleus delivery technique: (a) phacosandwich, (b) fishhook, (c) irrigating vectis, (d) viscoexpression, and (e) anterior chamber maintainer (ACM). Visual outcome, intraoperative, and postoperative complications were evaluated in detail. Follow-up was done on first and seventh postoperative days (PODs) and then at fourth and eighth postoperative weeks. Results The most common intraoperative complication was intraoperative miosis, followed by intraoperative hyphema, seen more in phacosandwich and irrigating vectis groups. The most common postoperative complication was striate keratopathy followed by transient postoperative corneal edema and AC inflammatory response, seen more in phacosandwich and fishhook groups. With reference to visual acuity, on the first POD 95% cases of ACM group achieved visual acuity >+0.5 logMAR unit. The difference in the visual outcome among groups was statistically significant. On fourth and eighth postoperative weeks, best-corrected visual acuity among various groups was comparable. Conclusion ACM and viscoexpression are effective techniques for early visual rehabilitation. Fishhook has limited utility in softer nuclear grades and black cataracts. Phacosandwich is more suitable for nuclear sclerosis Grades 3-4. Irrigating vectis, viscoexpression, and ACM technique are effective techniques for all grades of nucleus Postoperative surgical-induced astigmatism was comparable in all techniques.

[PMID: 28214101 DOI: 10.1016/j.ophtha.2017.01.026] [Citation(s) in RCA: 121] [Impact Index Per Article: 17.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Revised: 01/12/2017] [Accepted: 01/17/2017] [Indexed: 11/17/2022] Open
Abstract
PURPOSE To compare the postoperative endophthalmitis rate before and after initiation of intracameral (IC) moxifloxacin prophylaxis for both phacoemulsification and sutureless, manual small-incision cataract surgery (M-SICS), as well as in patients with posterior capsular rupture (PCR). DESIGN Retrospective, clinical registry. PARTICIPANTS All cataract surgeries (617 453) performed during the 29-month period from January 2014 to May 2016 at the 10 regional Aravind eye hospitals were included. METHODS The electronic health record data for all study eyes were analyzed. Endophthalmitis rates before and after moxifloxaxin were statistically compared for all eyes and separately for both phacoemulsification and M-SICS, and for the eyes complicated by PCR. MAIN OUTCOME MEASURES The postoperative endophthalmitis rates before and after initiation of IC moxifloxacin prophylaxis. RESULTS Overall, 302 815 eyes did not receive IC moxifloxacin and 314 638 eyes did, and there was a significant decline in the endophthalmitis rate, from 0.07% (214/302 815) to 0.02% (64/314 638) (P < 0.001), with moxifloxacin. For the 194 252 phacoemulsification eyes, the endophthalmitis rate was 0.07% (75/104 894) without IC moxifloxacin prophylaxis, compared with 0.01% (11/89 358) with moxifloxacin (P < 0.001). For the 414 657 M-SICS eyes, the endophthalmitis rate was 0.07% (135/192 149) without IC moxifloxacin prophylaxis, compared with 0.02% (52/222 508) with moxifloxacin (P < 0.001). Approximately half of the 8479 eyes that had PCR received IC moxifloxacin, and half did not. Without IC moxifloxacin, PCR increased the endophthalmitis rate nearly 7-fold to 0.48% (20/4186); IC moxifloxacin reduced the endophthalmitis rate with PCR to 0.21% (9/4293) (P = 0.034). No adverse events were due to IC moxifloxacin. CONCLUSIONS Routine IC moxifloxacin prophylaxis reduced the overall endophthalmitis rate by 3.5-fold (3-fold for M-SICS and nearly 6-fold for phacoemulsification). There was also a statistical benefit for eyes complicated by PCR, and IC antibiotic prophylaxis should be strongly considered for this high-risk population. These conclusions are strengthened by the high volume of cases analyzed at a single hospital network over a comparatively short time frame. Considering the association of hemorrhagic occlusive retinal vasculitis with vancomycin and the commercial unavailability of IC cefuroxime in many countries, moxifloxacin appears to be an effective option for surgeons electing IC antibiotic prophylaxis.

Intraocular Pressure Reduction after Phacoemulsification versus Manual Small-Incision Cataract Surgery: A Randomized Controlled Trial. Ophthalmology 2016; 123:1695-1703. [PMID: 27234929 DOI: 10.1016/j.ophtha.2016.04.014] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2015] [Revised: 03/29/2016] [Accepted: 04/06/2016] [Indexed: 11/21/2022] Open
Abstract
PURPOSE To compare reduction in intraocular pressure (IOP) and change in anterior chamber angle configuration between eyes undergoing phacoemulsification versus those undergoing manual small-incision cataract surgery (MSICS). DESIGN Prospective, randomized, double-masked, parallel assignment clinical trial. PARTICIPANTS Five hundred eyes of 500 participants 40 to 70 years of age with normal IOP, gonioscopically open angles, and age-related cataract. METHODS Eyes underwent phacoemulsification or MSICS after a 1:1 randomization and allocation code. Best-corrected vision, IOP, comprehensive slit-lamp evaluation, and anterior segment (AS) optical coherence tomography (OCT) were performed at baseline and at 1, 3, and 6 months follow-up. MAIN OUTCOME MEASURES Change in IOP (ΔIOP) and AS OCT parameters between baseline and 6 months after surgery. RESULTS Six months, similar IOP reduction was observed in eyes undergoing phacoemulsification (ΔIOP = 2.7±2.9 mmHg) and MSICS (ΔIOP = 2.6±2.6 mmHg; P = 0.70). Widening of the angle opening distance (AOD) 500 μm from the scleral spur (median ΔAOD500 = 103 μm; interquartile range = 39-179 μm) was also similar in both groups (P = 0.28). Multivariate linear regression analysis showed that eyes with higher baseline IOP experienced significantly greater reduction in IOP at 6 months (ΔIOP = 0.46-mmHg reduction for every 1-mmHg increment in baseline IOP; 95% confidence interval [CI], 0.4-0.5 mmHg; P < 0.001). After adjusting for covariates, the magnitude of widening of AOD500 was not associated significantly with reduction in IOP (1.33-mmHg reduction for every 1-mm increment in AOD500; P = 0.07). Baseline AOD500 (β = -0.60-mm change/1-mm increment of baseline AOD; 95% CI, -0.67 to -0.53 mm) and anterior chamber depth (β = 0.07-mm change/1-mm increment of baseline anterior chamber depth; 95% CI, 0.04-0.1 mm) were significant predictors of AOD500 widening at 6 months. CONCLUSIONS Both phacoemulsification and MSICS led to significant and similar IOP reductions 6 months after surgery, and both surgeries produced similar changes in anterior chamber and angle parameters. Higher baseline IOP was associated with greater IOP reduction; IOP reduction also can be attributed partly to changes in angle and anterior chamber configuration, although these parameters were unable to predict significantly predict IOP drop at 6 months.

Abstract
PURPOSE To compare the rate of postoperative endophthalmitis before and after initiation of intracameral (IC) moxifloxacin for endophthalmitis prophylaxis in patients undergoing cataract surgery. DESIGN Retrospective, clinical registry. PARTICIPANTS All charity and private patients (116 714 eyes) who underwent cataract surgery between February 15, 2014, and April 15, 2015, at the Madurai Aravind Eye Hospital were included. Group 1 consisted of 37 777 eyes of charity patients who did not receive IC moxifloxacin, group 2 consisted of 38 160 eyes of charity patients who received IC moxifloxacin prophylaxis, and group 3 consisted of 40 777 eyes of private patients who did not receive IC moxifloxacin. METHODS The electronic health record data for each of the 3 groups were analyzed, and the postoperative endophthalmitis rates were statistically compared. The cost of endophthalmitis treatment (groups 1 and 2) and the cost of IC moxifloxacin prophylaxis (group 2) were calculated. MAIN OUTCOME MEASURES Postoperative endophthalmitis rate before and after initiation of IC moxifloxacin endophthalmitis treatment cost. RESULTS Manual, sutureless, small incision cataract surgery (M-SICS) accounted for approximately all of the 75 937 cataract surgeries in the charity population (97%), but only a minority of the 40 777 private surgeries (21% M-SICS; 79% phacoemulsification). Thirty eyes in group 1 (0.08%) and 6 eyes in group 2 (0.02%) were diagnosed with postoperative endophthalmitis (P < 0.0001). The group 3 endophthalmitis rate was 0.07% (29 eyes), which was also higher than the second group's rate (P < 0.0001). There were no adverse events attributed to IC moxifloxacin in group 2. The total cost of treating the 30 patients with endophthalmitis in group 1 was virtually identical to the total combined cost in group 2 of routine IC moxifloxacin prophylaxis and treatment of the 6 endophthalmitis cases. CONCLUSIONS Routine IC moxifloxacin prophylaxis achieved a highly significant, 4-fold reduction in postoperative endophthalmitis in patients undergoing M-SICS. Compared with previous studies, having such a high volume of patients undergoing surgery during a relatively short 14-month time period strengthens the conclusion. This study provides further evidence that moxifloxacin is an effective IC prophylactic antibiotic and suggests that IC antibiotics should be considered for M-SICS and phacoemulsification.

Abstract
PURPOSE A systematic review and meta-analysis comparing the safety, efficacy, and expenses related to phacoemulsification versus manual small incision cataract surgery (SICS). METHODS PubMed, Cochrane, and Scopus databases were searched with key words manual SICS 6/18 and 6/60; astigmatism and endothelial cell loss postoperatively, intra- and post-operative complications, phacoemulsification, and comparison of SICS and phacoemulsification. Non-English language manuscripts and manuscripts not indexed in the three databases were also search for comparison of SICS with phacoemulsification. Data were compared between techniques for postoperative uncorrected and corrected distance visual acuity (UCVA and best corrected visual acuity [BCVA], respectively) better than 6/9, surgical cost and duration of surgery. The Oxford cataract treatment and evaluation team scores were used for grading intraoperative and postoperative complications, uncorrected near vision. RESULT This review analyzed, 11 comparative studies documenting 76,838 eyes that had undergone cataract surgery considered for analysis. UCVA of 6/18 UCVA and 6/18 BCVA were comparable between techniques (P = 0.373 and P = 0.567, respectively). BCVA of 6/9 was comparable between techniques (P = 0.685). UCVA of 6/60 and 6/60 BCVA aided and unaided vision were comparable (P = 0.126 and P = 0.317, respectively). There was no statistical difference in: Endothelial cell loss during surgery (P = 0.298), intraoperative (P = 0.964) complications, and postoperative complications (P = 0.362). The phacoemulsification group had statistically significantly less astigmatism (P = 0.005) and more eyes with UCVA of 6/9 (P = 0.040). UCVA at near was statistically significantly better with SICS due to astigmatism and safer during the learning phase (P = 0.003). The average time for SICS was lower than phacoemulsification and cost <½ of phacoemulsification. CONCLUSION The outcome of this meta-analysis indicated there is no difference between phacoemulsification and SICS for BCVA and UCVA of 6/18 and 6/60. Endothelial cell loss and intraoperative and postoperative complications were similar between procedures. SICS resulted in statistically greater astigmatism and UCVA of 6/9 or worse, however, near UCVA was better.

Abstract
Cataract is the leading cause of reversible blindness and visual impairment globally. Blindness from cataract is more common in populations with low socioeconomic status and in developing countries than in developed countries. The only treatment for cataract is surgery. Phacoemulsification is the gold standard for cataract surgery in the developed world, whereas manual small incision cataract surgery is used frequently in developing countries. In general, the outcomes of surgery are good and complications, such as endophthalmitis, often can be prevented or have good ouctomes if properly managed. Femtosecond laser-assisted cataract surgery, an advanced technology, can automate several steps; initial data show no superiority of this approach over current techniques, but the results of many large clinical trials are pending. The greatest challenge remains the growing 'backlog' of patients with cataract blindness in the developing world because of lack of access to affordable surgery. Efforts aimed at training additional cataract surgeons in these countries do not keep pace with the increasing demand associated with ageing population demographics. In the absence of strategie that can prevent or delay cataract formation, it is important to focus efforts and resources on developing models for efficient delivery of cataract surgical services in underserved regions.

Abstract
PURPOSE Cataract surgery is provided both by the private and public sector in India. Free cataract surgery (with minimal amenities) funded through subsidies/reimbursements by government and non-governmental organizations is provided for underprivileged and poor patients, especially in rural areas. However, no evidence exists whether this free surgery is used by those who could afford to pay and are willing to pay for cataract surgery. So, understanding willingness to pay and preferences for cataract surgery in the population can have important policy implications. METHODS A cross-sectional survey of 1272 households from four randomly drawn rural household clusters in Theni district, Tamilnadu state, India was conducted. Respondents from households were presented with scenarios (with and without free surgery availability) to elicit their willingness to pay and preferences for cataract surgery. RESULTS Of those willing to undergo surgery; 696 (57%) were willing to undergo paid surgery, 148 (12%) only free surgery, and 378 (31%) paid surgery if no free surgery was available. In a multinomial logit model, household wealth measures, income variables and family history of cataract surgery largely distinguished the preferences. Good understanding of cataract and its intervention only marginally influenced preference for paid surgery. CONCLUSION A larger number of people were willing to pay when free surgery was not available. Free surgery may be crowding out surgery for which costs can be recovered. With non-cataract causes of blindness in the Indian population also requiring attention, this has implications for allocation of scarce resources.
