Aim: To assess the complications and visual outcomes associated with cataract surgery in camp patients operated at a tertiary centre. Materials and methods: In a retrospective study, 206 outreach camp patients had undergone cataract surgeries with posterior chamber intraocular lens implantation under peribulbar anesthesia over a period of 6 months. Post-operative complications on Day 1 were graded as per Oxford Cataract Treatment and Evaluation Team (OCTET) definitions. One month postoperative complications, best corrected visual acuity and refractive errors were assessed. Results: 206 eyes underwent cataract extraction with PCIOL implantation. Small incision cataract surgery (SICS) was the commonest method (78.6%) used. The most common first post-operative day complication was mild iridocyclitis (26.2%). The complications were based on OCTET definitions, and showed that 33 % had Grade I and 3.4 % had Grade II complications. The major post-operative complication after 4 weeks of surgery was posterior capsular opacity. 89.8 % of the eyes had a 4 week-post-operative best corrected visual acuity of e” 6/24. The commonest refractive error was myopia with against the rule astigmatism, seen in 86 out of 150 cases. Conclusion: High quality cataract surgery with a low rate of intra-operative complications and good visual outcome can be attained in camp patients operated in the base hospitals, thus justifying more similar screening camps to clear the vast cataract backlog.

To evaluate changes in macular thickness via-a-vis visual acuity post uncomplicated manual small incision cataract surgery (MSICS) & phacoemulsification surgery Prospective clinical study on 160 patients of uncomplicated immature senile cataract, aged 40-70yrs, patients were randomised into two groups, MSICS & phacoemulsification, by simple 1:1 randomization, who underwent uncomplicated cataract surgery with posterior chamber intraocular lens (PCIOL). Post-operatively, the patients were evaluated for best corrected visual acuity (BCVA) and changes in macular thickness by optical coherence tomography (OCT) at post-op Day 1, 7, 21, 48, and 12 weeks. Paired t-test was used for comparison across follow up. : At 12 weeks post-operative, mean logMAR BCVA was 0.01±0.02 for MSICS group and 0±0.02 for Phacoemulsification group. Macular thickness was not statistically significant (p=0.342) between MSICS group (219.19±17.88µm) and Phacoemlusification group (215.61±16.21µm), at the end of 12 weeks post-operative. Clinically significant macular oedema was not diagnosed in any of the patients at the follow-ups.: Both procedures achieved good post-operative Best Corrected visual acuity without significant differences in BCVA between both the groups at the end of 12 weeks.

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.

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.

Objective To present the surgical outcome of posterior chamber intraocular lens scleral fixation using a 27-gauge trocar-assisted transconjunctival sutureless technique in aphakic patients due to cataract surgery complications with inadequate capsular support. Methods Six consecutive patients with aphakia due to cataract surgery complications with inadequate capsular bag support were operated by two surgeons. Intraocular lens scleral fixation was performed with a 27-gauge trocar-assisted transconjunctival sutureless technique. Patients were followed-up for 12 months. Preoperative and postoperative best-corrected visual acuities were assessed with Early Treatment Diabetic Retinopathy Study charts and expressed in decimals. Results All patients showed statistically significant best-corrected visual acuity improvement and excellent anatomic results. Mean preoperative best-corrected visual acuity was 0.17 (range of 0.1–0.2). Mean postoperative best-corrected visual acuity was 0.84 (range of 0.63–1.00). Mean initial spherical equivalent refractive error was +11.85 (range of +9.00 to +15.00). Mean final spherical equivalent refractive error was –0.25 (range of –1.25 to +2.25). There were no postoperative complications during the whole follow-up. Conclusion Fixation of a posterior chamber intraocular lens using a 27-gauge trocar-assisted transconjunctival sutureless intrascleral technique is an excellent option for aphakic patients secondary to cataract surgery complications with inadequate capsular support.

Scleral Fixated Intraocular Lens

Introduction: Scleral fixated intraocular lens(SFIOL) implantation to correct aphakia offers superior visual rehabilitation in comparison to aphakic spectacles or contact lens. This study was done to evaluate a simplified technique of scleral fixation of posterior chamber intra-ocular lens (IOL) in terms of visual outcome and complications.Methods: This was a prospective study enrolling 23 eyes of 23 patients who underwent anterior vitrectomy followed by ab-externo sclera fixation of posterior chamber IOL using 10.0 polypropylene sutures from January 2016 to February 2017 in Nepal Eye Hospital.Scleral flap was made at 3 and 9'o clock meridian to cover the knots which prevent erosion of the knots through conjunctiva.  Main outcome measures were post-operative best corrected visual acuity and post-operative complications.Result: Best corrected visual acuity were 6/6 - 6/18 in 86.9% (n=20), 6/24 - 6/60 in 8.7% (n=2) and worse than 6/60 in 4.3% (n=1)at six months followup. The mean spherical equivalent before surgery was +10.60 diopter and -1.14 diopter post-surgery. The common indicationsfor scleral fixated intraocular lens weretrauma in 60.86% (n=14), surgical aphakia in21.73% (n=5), spontaneous posterior dislocation of lens in 13.0% (n=3) and subluxated intraocular lens in 4.34% (n=1). The common complications were astigmatism in 91.30% (n=21), decentered IOL in 4.34% (n=1) and uveitis in 4.35% (n=1).Conclusion: Ab-externosclerated fixated intraocular lens is a safe and effective method for visual rehabilitation with low post-operative risk.

To study "small incision cataract surgery (SICS)" for the rehabilitation of cataract visually impaired and blind patients, a retrospective study of 100 cases of cataract patients with small incision cataract surgery (SICS) with posterior chamber intraocular lens (PCIOL) implantation were done at Rajshahi Medical College Hospital. All cases were selected having corrected visual acuity less than 6/60 who were admitted at the Department of Ophthalmology for cataract surgery from March, 2006 to February, 2008. Age group of the patient range from 40 to 85 years. Age related senile cataract were selected any complicated cataract was excluded from the study. All these patients underwent SICS with 5.5 mm optic polymethylmethacrylate (PMMA) non-foldable posterior chamber intraocular lens (PCIOL) were implanted by irrigation vectis. Intra operative complication were present in 8% cases among them 3 cases (3%) required to conversion to Conventional Extracapsular Cataract Extraction (ECCE). 2 cases (2%) had small posterior capsular rent (PCR), 1 case (1%) irido dialysis & 2 cases (2%) hyphaema occurred. Postoperative complications were found in 38 cases (38%) among them transient corneal oedema occurred in 18 cases (18%) iritis occurred in 13 cases (13%), decentering of intraocular lens (IOL) occurred in 2 cases, corrected visual acuity after 6 weeks of operation were 6/12 or better in 97 cases (97% cases achieved functional vision). Induced astigmatism ± 0.50 D to ± 1.00 D occurred in 94 cases (94%) and ± 1.500 to 2.50D in 6 cases (6%). So, SICS may be the choice of surgery in respect of visual outcome with the limited facilities and surgeons. DOI: 10.3329/taj.v22i1.5037 TAJ 2009; 22(1): 132-135

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.

A Prospective randomized controlled study was conducted to compare outcome of Small IncisionCataract Surgery (SICS) using microscope or loupe magnification.Two hundred fifty one patient with mature cataract were randomly allocated to SICS-FishhookTechnique with either microscope (127 eyes) or loupe (124 eyes) magnification. Intra- andpostoperative complications and immediate visual outcome were analyzed.Nearly two third (microscope 65% and magnifying loupe 62.9%) of all patients had good visualoutcome on first postoperative day. Poor outcome (<6/60) was recorded in 8% (microscope group)and 7% (magnifying loupe group). Mean visual acuity with Snellen was 0.39 (SD 0.2) in microscopegroup and 0.38 (SD 0.2) in magnifying loupe group. Intra operative complications were comparablein both groups. Mean surgery time with loupe magnification was significantly shorter.Comparatively equivalent good surgical outcome was achieved with loupe as well as with microscopemagnification. However performing SICS with loupe magnification is significantly faster. Smallincision cataract surgery with loupe magnification is safe and effective procedure for cataract surgeryso it can play a role in reducing cataract blindness in developing countries of the world.Key words: loupe, magnification, microscopic, cataract, surgery
