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 & Objectives: Capsulotomy is one of the important step in cataract surgery which can affect the surgical outcomes. The aim of the study was to compare the outcomes of envelope and continuous curvilinear capsulorhexis technique in manual small incision cataract surgery (MSICS). Materials & Methods: A total of 72 eyes of 72 patients undergoing MSICS were studied. The patients were equally divided into two groups i.e. 36 patients each in envelope capsulotomy (Group A) and continuous curvilinear capsulotomy (CCC) group (Group B).Results: Mean surgical time (±SD) in Group A was 355.83 sec ±37.79 sec and in Group B was 375 sec ±31.214 (p=0.02). Uncorrected visual acuity on postoperative day 1 was 6/9 or better in 50% (18) cases in Group A and in 36% (13) cases in Group B (p=0.28). Best corrected visual acuity (BCVA) on post-operative week 12 was 6/9 or better in 30.6% (n=11) cases in Group A and in 36% (n=13) cases in Group B (p=0.43). On 12th week postoperatively, Grade 2 posterior capsular opacification (PCO) was seen in 30.6 % (n=11) cases of Group A and in 16.6 % (n=6) cases of Group B (p=0.17). Conclusion: CCC technique can be considered superior to envelope technique for long term visual rehabilitation.JCMS Nepal. 2016;12(1):10-13.

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
