ABSTRACT
Purpose: Globally, cataracts have remained the major cause of blindness. Cataract accounts for 62.6% of blindness affecting 9� million people. The only treatment for cataracts is surgical removal of cataracts. The surgical procedures include phacoemulsification and extracapsular cataract extraction (ECCE). In India, there is a huge backlog of cataract patients. Phacoemulsification is preferred nowadays for early visual rehabilitation, but in developing countries like ours, where facilities are not widely available, small-incision cataract surgery (SICS) is a cost-effective alternative as no machine is required. Also, it provides early visual rehabilitation as it is sutureless when compared to ECCE. So, manual SICS has emerged as a substitute for phacoemulsification and ECCE. The aim of the study was to evaluate the visual acuity and surgically induced astigmatism in patients more than 40 years of age, undergoing manual SICS with nucleus management by viscoexpression technique. Methods: This was a prospective study that included 50 patients over the age of 40 years undergoing manual SICS at a tertiary health-care center in North India by viscoexpression technique. Only those patients whose functional visual disability could be attributed to cataracts were included in the study. Preoperative and postoperative astigmatism were analyzed in the first, fourth, and sixth weeks. Results: Fifty patients who were undergoing manual SICS were analyzed. Preoperative best-corrected visual acuity (BCVA) and astigmatism were compared to postoperative BCVA and astigmatism. Of 50 patients, 48 (96%) patients were able to gain good vision after 6 weeks. Conclusion: This study showed early visual rehabilitation with less surgically induced astigmatism following manual SICS by viscoexpression technique.
