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.

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.

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.

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: Seasonal hyper-acute panuveitis (SHAPU) is a sight-threatening disease and its management is challenging. Objective: To study the profile and evaluate the visual outcome of the patients of clinicallydiagnosed cases of SHAPU after treatment. Subjects and methods: A retrospective interventional hospital-based study was carried out involving 21 subjects with clinically-diagnosed SHAPU. The data were retrieved from the record section of the hospital and analyzed. The variables studied were demographic pattern, clinical condition, duration of presentation and visual acuity before and after the treatment. Statistics: The data were analyzed using Epi Info version 2000. Percentage prevalence, mean values with standard deviation, relative risk, 95% CI and p value were calculated. P value of < 0.05 was considered to be significant. Results: Among the 21 cases, the numbers of male and female were 11 (52.4 %) and 10 (46.7 %) respectively. A comparative analysis of gender in children and adults did not show any significant difference (RR=0.47, 95% CI = 0.22 - 1.01, Fisher exact test: p = 0.14). The mean for all ages was 7 ± 12.68 years, while the mean age in pediatric cases was 4.5 ± 3.91 years. Thirteen (61.9%) cases occurred in children below fifteen years. Fifteen (71.4 %) cases reported during September and October. Presenting visual acuity of all cases was less than 3/60. All of them received medical treatment. By the end of the 4th week, seven (33.3 %) patients regained vision to 6/18. Conclusion: SHAPU is more prevalent in pediatric age group. It is equally prevalent among males and females. The visual acuity can improve with early medical treatment. Keywords: SHAPU; panuveitis; steroid; phthisis bulbi DOI: 10.3126/nepjoph.v2i1.3702 Nep J Oph 2010;2(1) 35-38

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.

Objective: Aim of the study is to Compare the astigmatism induced by a reduced temporal sclerocorneal tunnel incision manual small incision cataract surgery with an extended temporal clear corneal Phacoemulsification of similar width . Methods: A Prospective, randomised controlled study was carried out in 224 selected patients who were again divided into two groups - Group A (112 patients) and Group B (112 patients). Group A patients underwent temporal manual small incision cataract surgery with a 5.5 mm sclerocorneal incision and Group B underwent phacoemulsification by a 2.8 mm clear corneal temporal incision which was extended to 5.5 mm before IOL implantation. In both groups, a 5.25 mm rigid PMMA IOL was implanted in the bag. UCVA and BCVA of both group of patients was quantified and analyzed at 1 week and at 6 weeks Observation: It was seen that the mean surgically Induced astigmatism in group A (N=112) was 0.5625D , which was slightly lesser than that in Group B (N=112) which was 0.65D, although the p-value of 0.26 indicated that there was statistically no significant difference in visual outcomes between the two groups of patients. Here, a p-value of < 0.05 was considered statistically significant. Conclusion: In Skilled and Safe hands, refractive outcomes following performing a 5.5mm temporal sclerocorneal frown-incision manual small incision cataract surgery and a phacoemulsification procedure by a 2.8mm temporal clear corneal incision extended to 5.5mm for implanting a 5.25mm rigid PMMA IOL , are comparable.

Background: In developing countries, manual small incision cataract surgery is a better alternative and less expensive in comparison to phacoemulsification and thus the incision is an important factor causing high rates of postoperative astigmatism resulting into poor visual outcome. Thus, modifications to the site of the incision is needed to reduce the pre-existing astigmatism and also to prevent postoperative astigmatism. Modification to superotemporal incision relieves pre-existing astigmatism majorly due to its characteristic of neutralizing against-the-rule astigmatism, which is more prevalent among elderly population and thus improves the visual outcome. Aims: To study the incidence, amount and type of surgically induced astigmatism in superior and superotemporal scleral incision in manual SICS. Methodology: It is a randomized, comparative clinical study done on 100 patients attending the OPD of Ophthalmology at a tertiary care hospital, with senile cataract within a period of one year and underwent manual SICS. 50 of them chosen randomly for superior incision and rest 50 with superotemporal incision. MSICS with PCIOL implantation were performed through unsutured 6.5 mm scleral incision in all. Patients were examined post-operatively on 1st day, 7th day, 2nd week and 4th week and astigmatism was evaluated and compared in both groups. Results: It is seen that on postoperative follow up on 4th week, 77.78% of the patients with ATR astigmatism who underwent superior incision had increased astigmatism whereas, only 13.63% of the patients with ATR astigmatism who underwent supero-temporal incision, had increased astigmatism but 81.82% had decreased ATR astigmatism. However, 77.78% of the patients with preoperative WTR astigmatism who underwent supero-temporal incision, had increased astigmatism, whereas 44.45% of the patients with WTR astigmatism preoperatively, had increased astigmatism in contrast to 50% had decreased amount of astigmatism. It is also seen that the supero-temporal incision group had more number of patients (78%) with visual acuity better than 6/9 at 4th postoperative week than superior incision group (42%). Conclusion: This study concludes that superior incision cause more ATR astigmatism postoperatively whereas superotemporal incision causes lower magnitude of WTR astigmatism, which is advantageous for the elderly. Besides superotemporal incision provides better and early visual acuity postoperatively.

BACKGROUND Traumatic cataract is one of the common sequelae following ocular injury. It is one of the leading causes of preventable blindness. Ocular trauma leading to traumatic cataract, if managed early gives good visual outcome. Associated ocular structure involvement has much bearing on the management and prognosis of traumatic cataract. We wanted to study the visual outcome of cataract surgery in traumatic cataract. METHODS All patients included in this prospective study were subjected complete ocular examination, intra ocular lens (IOL) power calculation and small incision cataract surgery (SICS) with IOL implantation. Visual outcome was assessed after 1st week, 2 nd week, 6th week and 6 months. Postoperative visual outcome and post-operative complications were assessed. RESULTS Out of 50 cases studied, 56 % of cases were in the age group of less than 20 years. Male: Female ratio was 2.57 : 1. Traumatic cataract was higher in patients of rural background as compared to urban background (64 % vs 32 %). In 58 % of cases, penetrating injury was the type of trauma. 60 % of patients had visual acuity of less than 3/60 at presentation. Corneal injuries (34 %), scleral tear in (22 %) and iris related problems (18 %) were the most common associated findings. All the patients were treated with SICS with IOL implantation. Most common intra-operative complication was posterior capsule rupture seen in 14 % of cases, 34 % of patients had anterior uveitis as early post-operative complication and 24 % of patients developed PCO as late post-operative complication; 68 % of the patients achieved visual acuity of above 6/18. CONCLUSIONS Timely management and involvement of other structures in traumatic cataract determines the visual prognosis of cataract surgery in traumatic cataract. Thus, our study showed that traumatic cataract can be successfully managed surgically with intraocular lens implantation with good visual outcome, unless there is associated corneal opacity or posterior segment involvement. More emphasis should be laid on the preventive measures like mass health education and awareness about risk of ocular trauma, and need to adopt safety measures should be focused, especially during playground, and at workplace.
