Comparative study of the complications during small incision cataract surgery and phacoemulsification
Abstract
Cataract poses a substantial economic and public health burden and is the leading cause of blindness worldwide. There are many modalities for treatment of cataract. This present study was conducted on 200 cataract cases to compare Small Incision Cataract Surgery (SICS) and Phacoemulsification (Phaco). Hundred cases of cataract were operated by SICS and 100 by Phaco. It can be concluded from this study that both intra-operative and postoperative complications were lesser in Phaco than SICS but there no significant difference in distribution of type of complications in both the groups. Among complications, the intra-operative most common complications in SICS was sutures at tunnel site in 19% of cases followed by premature entry in 11%, iris prolapse in 7%, incomplete capsulorrhexis in 5, need of enlargement of tunnel in 5%, Descemet's membrane detachment in 4% cases, posterior capsule tear in 2%, hyphema, zonular dialysis & vitreous loss in 1% of cases in each category. Surgery was prolonged in 29% of cases. Whereas in phaco the most common complications was needed enlargement of tunnel in 4% of cases followed by premature entry in 3%, capsulorrhexis in 2%, DM detachment & iris prolapse each in 1%. Conversion to SICS was 2% and in 7% of cases sutures were applied at tunnel site and surgery took long time in 7 cases. In phaco group only two type of postopeartive complication i.e. corneal oedema and previously undiagnosed ARMD was found whereas in SICS group eight postoperative complications were found.

Introduction
Cataract is clouding of the natural lens, one of the parts of the eye responsible for focusing light and producing clear sharp images. Cataract poses a substantial economic and public health burden and is the leading cause of blindness worldwide, accounting for nearly 48% of all blindness.1
The World Health Organization estimates the current global prevalence of blindness is 0.57% (range 0.2%-1%), with more than 82% of all blindness occurring in individual aged 50 and older. Cataract accounts for 47.8% of the world's roughly 37 million blind individual2 of note approximately 90% of the contribution in this study was seen in developing countries.
The only cure for cataract is removal. The art of cataract extraction has been known to our ancient forefathers at the beginning of civilization. Sushruta (1000 BC), early Egyptian, Greeks and Romans practiced this art in the form of either reclination, depression or 'couching', as it has been called.
Conclusion
It can be concluded from this study that both intra-operative and postoperative complications were lesser in Phaco than SICS but there no significant difference in distribution of type of complications in both the groups.
The intraoperative most common complications in SICS was sutures at tunnel site in 19% of cases followed by premature entry in 11%, iris prolapse in 7%, incomplete capsulorrhexis in 5, need of enlargement of tunnel in 5%, Descemet's membrane detachment in 4% cases, posterior capsule tear in 2%, hyphema, zonular dialysis & vitreous loss in 1% of cases in each category. Surgery was prolonged in 29% of cases. Whereas in phaco the most common complications was needed enlargement of tunnel in 4% of cases followed by premature entry in 3%, capsulorrhexis in 2%, DM detachment & iris prolapse each in 1%. Conversion to SICS was 2% and in 7% of cases sutures were applied at tunnel site and surgery took long time in 7 cases. In phaco group only two type of postopeartive complication i.e. corneal oedema and previously undiagnosed ARMD was found whereas in SICS group eight postoperative complications were found.
