Introduction: Cataract is most common cause of curable blindness worldwide and cataract surgery is most common procedure performed in ophthalmology. Posterior capsular opacification (PCO) is most common complication after cataract surgery which is usually treated with Neodymium-doped: Yttrium Garnet (Nd:YAG) laser posterior capsulotomy or occasionally with a surgical capsulotomy. The incidence and severity of PCO correlates to the type of surgical technique, IOL optic edge designs and IOL materials. Material and Methods: 70 eyes of 64 patients operated for age related cataract were studied in this prospective interventional study. Phacoemulsification was done in 35 eyes and SICS in 35 eyes with hydrophobic single piece biconvex foldable intraocular lens. Patients were followed up at 1, 3, 6, 9 and 12 months for the development of PCO. Clinically significant PCO (loss of 2 or more lines of Snellen’s visual acuity chart) was treated with Nd:YAG laser capsulotomy. Results: The overall incidence of PCO was 22.85%. Amongst the patients who developed PCO, SICS and phacoemulsification was performed in 62.5% and 37.5% patients respectively. Result was statistically significant with p value <0.05 using z test. On first postoperative day, patients operated with phacoemulsification had better visual acuity than SICS. Conclusion: Phacoemulsification can provide early and better visual outcome than SICS and has lower incidence of PCO formation which may be due to difference in irrigation and aspiration and less disruption of blood aqueous barrier than SICS. PCO can be reduced by atraumatic surgery and thorough cortical clean up and capsular polishing.

To evaluate the visual outcome in patients who have had their cataract surgery in a tertiary hospital of Chittagong district in Bangladesh. This is a clinic-based study of consecutive cataract-operated patients who had age-related cataract with vision less than <6/60 before surgery. A total of 228 patients who visited the hospital and met the eligibility criteria were included in the study. The mean age of the patients was 62.46± 10.14 years and 134 (58.8%) were female. A total of 456 surgeries were performed on 228 patients. The most common procedure was small incision cataract surgery (SICS) with intraocular lens (IOL) implantation, operated in 422(92.5%) eyes. Among cataract-operated eyes, 290 (64%) had presenting vision >6/18 and <6/60 were found in 11 (2.4%) eyes. In most of the cases, visual acuity has improved after best correction as the percentages with the best correction were 402(88%) and 7(1.55%) respectively. Analysis of multiple logistic regression shows that patient’s older age (OR 9.101; 95% CI 3.331, 24.869), gender female (OR 2.374 CI 1.403, 4.017), literacy (OR 1.660; CI 1.009, 2.733) and SICS surgery technique (OR 3.540; CI1.298, 9.659) were significantly associated with poor visual outcome. Overall, this study demonstrates that cataract surgery can restore good visual acuity. However, the visual outcome needs to be improved to meet the WHO standard, and more attention should be directed towards monitoring of outcomes and correction of refractive error after cataract surgery.

Background: Age related cataract is the leading cause of blindness and visual impairment throughout the world. With the advent of microsurgical facilities simple cataract extraction surgery has been replaced by small incision cataract surgery (SICS) with posterior chamber intra ocular lens implant, which can be done either with clear corneal incision or scleral incision. Objective: To compare the post operative visual outcome in these two procedures of cataract surgery. Materials and method: This comparative study was carried out in the department of Ophthalmology, Delta Medical College & Hospital, Dhaka, Bangladesh, during the period of January 2010 to December 2012. Total 60 subjects indicated for age related cataract surgery irrespective of sex with the age range of 40-80 years with predefined inclusion and exclusion criteria were enrolled in the study. Subjects were randomly and equally distributed in 2 groups; Group A for SICS with clear corneal incision and group B for SICS with scleral incision. Post operative visual out come was evaluated by determining visual acuity and astigmatism in different occasions and was compared between groups. Statistical analysis was done by SPSS for windows version12. Results: The highest age incidence (43.3%) was found between 61 to 70 years of age group. Among study subjects 40 were male and 20 were female. Preoperative visual acuity and astigmatism were evenly distributed between groups. Regarding postoperative unaided visual outcome, 6/12 or better visual acuity was found in 19.98% cases in group A and 39.6% cases in group B at 1st week. At 6th week 6/6 vision was found in 36.3% in Group A and 56.1% in Group B and 46.2% in group A and 66% in group B without and with correction respectively. With refractive correction, 6/6 vision was attained in 60% subjects of group A and 86.67% of group B at 8th week. Post operative visual acuity was statistically significant in all occasions. Postoperative astigmatism of >0.50D was in 82.5% subjects of group A and 52.8% subjects of group B at 1st week. At 6th week postoperative astigmatism of less than 1D was in 79.95% subjects of Group A and 83.34% subjects of Group B. About 20% subjects in Group A and only 3.3% in Group B showed astigmatism of more than 1D and these differences on both the occasions were statistically significant. Conclusion: The post operative visual outcome was better in SICS with scleral incision (group B) than in SICS with clear corneal incision (Group-A).

Introduction: The small-incision cataract surgery is gaining popularity among the ophthalmic surgeons. Objective: To compare the visual outcome of conventional extra-capsular cataract extraction (ECCE) and small-incision cataract surgery (SICS) in a hospital based community cataract program. Materials and methods: A prospective interventional study without randomization was carried out including the patients undergoing cataract surgery by either conventional ECCE or manual SICS. They were followed up for 6 weeks postoperatively. The visual outcomes were compared between the two groups. Statistics: The statistical program Epi-Info version 2000 was used to analyze the data. Mean values with standard deviations, 95% CI and p value were calculated. The p value of <0.05 was considered significant. Results: Of 85 patients, 44 (M: F=10:34) underwent ECCE and 41 (M: F=15:26) SICS (RR= 0.71, 95% CI=0.42-1.2, p value=0.16). Unaided visual acuity on the 1st postoperative day in the ECCE group was e"6/ 18 in 22.7%,<6/18-6/60 in 63.6 %,< 6/60 in 13.7%, whereas in the SICS group, the same was e"6/18 in 70.7%,<6/18-6/60 in 22 %,< 6/60 in 7.3% (95% CI = 0.23 - 0.48, p=0.001). Best corrected visual acuity on the 6th week follow-up in the ECCE group was e"6/18 in 79.5%,<6/18-6/60 in 18.2 %,< 6/60 in 2.3% and in the SICS group the same was 6/18 in 90.5% and <6/18-6/60 in 4.9% (95% CI=0.44 - 0.73; p=0.0012). Conclusion: Both ECCE and SICS are good procedures for hospital based community cataract surgery but within the 6 weeks postoperative period SICS gives better visual outcome. Remarkably higher number of female patients can be provided service in a hospital based community cataract programme as compared to males.

Background: Several studies have shown comparable visual outcomes of SICS and phacoemulsification (Gogate et al 2007, Ruit et al 2007). Objective: To compare the safety and efficacy of different types of surgical procedures (phacoemulsification versus SICS) for cataract surgery in immature cataract. Material and methods: A prospective randomized controlled trial was carried out involving 93 and 89 patients with immature senile cataract selected for phacoemulsification and SICS respectively. Statistics: Mean values with standard deviations were calculated. P value of less than 0.05 was considered significant. Results: There was no difference between the groups in terms of gender, age and pre-operative visual acuity (p = 0.09). In phacoemulsification group (n=93) more than two thirds and in SICS group (n=89) more than three quarters of the patients had good visual outcome (6/6-6/18) on first postoperative day (p=0.065). Poor outcome (<6/60) was recorded in 6% (phacoemulsification group) and 1% (small incision cataract surgery group). Mean visual acuity was 0.43 ± 0.27 in phacoemulsification group and 0.47 ± 0.24 in SICS group. Mean surgery time was significantly shorter in SICS group (p=0.0003). Statistics: Data were computed and analyzed using the SPSS software program vs 10. The p value of < 0.05 was considered significant. Conclusion: There was no significant difference in visual outcome on first post operative day in between phacoemulsification and SICS technique. However, performing SICS was significantly faster. Small incision cataract surgery with implantation of rigid PMMA lens is a suitable surgical technique to treat immature cataract in developing countries.

BACKGROUND Posterior capsule opacification (PCO) is the most common delayed complication of cataract surgery. Nd:YAG (Neodymium yttrium aluminium garnet) laser posterior capsulotomy presents the advantages of a non-invasive, effective, relatively safe technique to manage intact posterior capsule that opacifies postoperatively. With this background we want to study the visual outcome and complications following Nd-YAG laser posterior capsulotomy in posterior capsular opacification following small incision cataract surgery (SICS). METHODS The study includes 64 patients attending outpatient department of a tertiary eye care hospital at Latur from June 2018 to May 2019 who have undergone SICS with PMMA PC IOL (polymethyl methacrylate posterior chamber intraocular lens) implantation and clinically diagnosed with posterior capsular opacification. 64 eyes with PCO were subjected to Nd:YAG laser posterior capsulotomy after detailed slit lamp bio microscopic examination pre- and post-capsulotomy. Follow-up was done at 1 hour, 1 week, 2 weeks and 4 weeks and patients were examined for visual outcome and any complications at each visit. RESULTS There were 16 males (25 %) and 48 females (75 %) with a mean age of 65 years. Posterior capsule opacification occurs within 3 years accounting for 46.9 % of the cases. Elschnig pearls type of PCO was more common when compared to fibrous type of PCO. Best corrected visual acuity (BCVA) before Nd:YAG laser capsulotomy was less than 6 / 60 in 35 patients (54.7 %) and within 6 / 60 to 6 / 24 in 23 patients (35. 9 %) with 6 patients (9.4 %) accounting for visual acuity between 6 / 24 to 6 / 18. After Nd - YAG Laser Capsulotomy, 46.9 % gained best corrected visual acuity of 6 / 18 or better, 39.1 % cases improved 6 / 12 and better and BCVA of 6 / 9, 6 / 6 was observed in 11 cases and 1 case respectively. Only 12 out of 64 patients had complications. Raised intraocular pressure (IOP) was found in 4 patients. Intraocular lens (IOL) pitting was found in 8 patients. CONCLUSIONS Nd:YAG laser capsulotomy is a safe, effective and a non-invasive procedure which avoids all the complications of surgical capsulotomy in patients of posterior capsule opacification.

Purpose: A retrospective study of the outcome of congenital and developmental cataract surgery was conducted in a public child eye health tertiary facility in children <16 years of age in Southern Nigeria, as part of an evaluation. Materials and Method: Manual Small Incision Cataract Surgery with or without anterior vitrectomy was performed. The outcome measures were visual acuity (VA) and change (gain) in visual acuity. The age of the child at onset, duration of delay in presentation, ocular co-morbidity, non ocular co-morbidity, gender, and pre operative visual acuity were matched with postoperative visual acuity. A total of 66 children were studied for a period of six weeks following surgery. Results: Forty eight (72.7%) children had bilateral congenital cataracts and 18 (27.3%) children had bilateral developmental cataracts. There were 38(57.6%) males and 28 (42.4%) females in the study. Thirty Five (53%) children had good visual outcome (normal vision range 6/6/ -6/18) post-operatively. The number of children with blindness (vision <3/60) decreased from 61 (92.4%) pre-operatively to 4 (6.1%) post-operatively. Post operative complication occurred in 6.8% of cases six week after surgery. Delayed presentation had an inverse relationship with change (gain) in visual acuity (r = - 0.342; p-value = 0.005). Pre-operative visual acuity had a positive relationship with post operative change (gain) in visual acuity (r = 0.618; p-value = 0.000). Conclusion: Predictors of change in visual acuity in our study were; delayed presentation and pre-operative VA. Cataract surgery in children showed clinical benefit.

To analyze the visual outcome in patients with pseudoexfoliation and to know the surgical parameters to cogitate in patients with pseudoexfoliation syndrome. An Observational study which was conducted in the Ophthalmology department in a tertiary care hospital in a rural area from June 2019 to December 2019. A total of 52 eyes of 52 patients aged 40 years and above, of either sex, clinically diagnosed with senile cataract and associated with pseudoexfoliation were enrolled in the study. After assessing best corrected visual acuity (BCVA), a detailed anterior and posterior segment examination was performed along with lacrimal sac syringing, manual keratometry, contact A-scan biometry and intraocular lens (IOL) power was calculated. All patients underwent manual small incision cataract surgery under peribulbar anaesthesia and intraocular lens was implanted. Intraoperative complications were noted during the surgery and was reported .Best corrected visual acuity was recorded on day 1, at 1week and at 1 month of follow up. Out of 52eyes of 52 patients, 29 were females (55.76%) and 38 eyes (73.07%) exhibited bilateral involvement. Distribution of the PXF material in various ocular structures was observed and majority of them (36.53%) had PXF material equally in iris, pupillary margin and lens. Based on the morphology of cataract associated with psudoexfoliation, nuclear cataract was the most commonly observed in 16 eyes (30.76%) and 42 eyes (80.76%) had moderate pupillary dilatation. The intraoperative difficulties observed during cataract surgery was poor pupillary dilatation which was managed by controlled sphincterotomy during the surgery in 3 eyes (5.76%), Iridiodialysis, rhexis extension, zonular dialysis each in 1 eye and posterior capsular rent in 2 eyes. Around 92.30% of the total study population achieved post-operative BCVA of 6/12 or better at 1month of follow up. Decreased visual acuity was noted in 2 (3.84%) eyes due to persistent corneal edema, one eye (1.92%) had posterior capsular opacification and one eye (1.92%) had cystoid macular edema. This study concludes that with careful preoperative assessment and necessary intraoperative precautions, good visual outcome can be achieved in patients with cataract with pseudoexfoliation.

Background: An effective method for cataract surgery should be identified to combat cataract blindness. Aim: To study the surgical outcome of conventional extracapsular cataract extraction versus manual small-incision cataract surgery. Materials and methods: A randomized clinical trial was carried out including one hundred eyes (88 patients) which were divided into two groups using systematic randomization: groups of conventional extracapsular cataract extraction with posterior chamber intraocular lens (ECCE with PCIOL) implantation and manual small-incision cataract surgery (MSICS). The postoperative parameters/variables studied were the unaided and best-corrected visual acuity and astigmatism. Statistics: Epi info 2000 version statistical software was used for data analysis and calculation of relative risk, 95% CI and p value. The p value of less than 0.05 was considered as significant. Results: In the immediate postoperative period, unaided visual acuity of =/> 6/18 was achieved in 24 subjects in MSICS group versus 7 in ECCE with PCIOL group (RR=2.05, 95% CI=1.44 - 2.94, p = 0.0002), whereas the same at 6 - 8 weeks postoperatively was found in 28 and 22 subjects in those groups respectively (RR=1.27, 95% CI=0.86-1.89, p=0.23). The astigmatism of =/> 2 at 6 - 8 weeks was found in 35 and 17 subjects from the conventional and MSICS groups respectively ( R=2.28, 95% CI = 1.39-3.73, p=0.0002). Conclusion: Both MSICS and conventional ECCE with PCIOL are safe and effective techniques for treatment of cataract patients. A more rapid recovery of good vision can be achieved with MSICS than with conventional ECCE with PCIOL in the immediate postoperative period.

Introduction: Manual small incision cataract surgery (MSICS) is a cost-effective alternative to phacoemulsification cataract surgery for developing countries. This prospective study was carried out in Combined Military Hospital (CMH), Chittagong from October 2009 to March 2011 on 75 cataract patients who were operated by MSICS technique. Objectives: Aim of this study was to assess the visual outcome and complications of MSICS in a peripheral CMH. Methods: Seventy five cataract patients were operated by MSICS technique. All surgical procedures were performed by the principal author. Major per-operative and postoperative complications were documented. Visual outcome was assessed by Snellen’s visual acuity test 06 weeks after operation. Results: Uncorrected visual acuity (UCVA) was 6/6 – 6/18 in 57 (76.0%) patients, < 6/18 – 6/60 in 15 (20%) and < 6/60 in 03 (4.0%) patients. Best corrected visual acuity (BCVA) was 6/6-6/18 in 65 (86.7%) patients, < 6/18-6/60 in 07 (9.3%) and < 6/60 in 03(4.0%) patients. Visual outcome was good in 86.7% of patients according to World Health Orgnization (WHO) criteria and was not far away from the WHO expected outcome. Posterior capsule rupture was the most significant per-operative complication which was found in 7(9.3%) cases and surgically induced astigmatism was main postoperative complication that affected visual outcome. Mean postoperative astigmatism (against-the rule) was - 1.25DC. 14 JAFMC Bangladesh. Vol 10, No 1 (June) 2014 Conclusion: MSICS is a safe and cost-effective technique of extra-capsular cataract extraction where surgical skill and experience of the surgeon plays a significant role in the result.
