To study safety and benefits of bilateral cataract surgery in a tertiary care ophthalmic centre of multi-specialty hospital in bilateral cataract cases DESIGN: Prospective study. MATERIALS AND METHODS: Prospective study done during May 2011 to Feb. 2012. A total 166 subjects underwent Bilateral Small Incision Cataract Surgery (SICS). Out of 166 subjects 83 subjects underwent Immediate Simultaneous Sequential Bilateral Cataract Surgery (ISBCS) in the same sitting, 83 subjects underwent bilateral cataract surgery at the interval of 48 hours Delayed simultaneous bilateral cataract surgery (DSBCS). RESULTS: All had uneventful convalescence, single hospital admission and simultaneous Bilateral Visual recovery. CONCLUSION: No case had post-operative sight threatening infections. Subjective motivation for ISBCS better than DSBCS as it was single OT visit and one time surgery KEYWORDS: Bilateral, simultaneous, immediate simultaneous bilateral cataract surgery. Delayed simultaneous bilateral cataract surgery. INTRODUCTION: Globally, the number of people of all ages visually impaired is estimated to be 285 million, of whom 39 million are blind. People 50 years and older represent 65% and 82% of visually impaired and blind, respectively. The major causes of visual impairment are uncorrected refractive errors (43%) followed by cataract (33%). 1. Blindness due to cataract often bilateral presents an enormous problem in India not only in terms of human morbidity but also in terms of economic loss and social burden. The main causes of blindness in India are as follows:-Cataract (62.60%) Refractive Error (19.70%) Corneal Blindness (0.90%), Glaucoma
