STUDY OF INTRAOPERATIVE COMPLICATIONS IN PATIENTS UNDERGOING SMALL INCISION CATARACT SURGERY AT A TERTIARY CARE CENTRE: A DESCRIPTIVE STUDY

Abstract

Background: In India,Cataract is the leading cause of avoidable blindness.2 and cataract surgery forms the major workload of most ophthalmic units in the country. An estimated 4 million people become blind because of cataract every year,3 which is added to a backlog of 10 million operable cataracts in India, whereas only 5 million cataract surgeries are performed annually in the country.4 Thus, a technique of cataract surgery that is not only safe and effective but also economical and easy for the majority of ophthalmologists. It is estimated that about 25% of poor outcomes of cataract operations performed in developing countries annually are due to surgical complications.19 Minimizing intraoperative complications of cataract surgery is an important step towards eliminating visual impairment caused by such complications. Aim & Objective:1. To study intra-operative complications of manual small incision cataract surgery. 2. To study the visual outcome in patients of intra-operative complications following its management. Methods: Prospective cross sectional study, Study setting: Ophthalmology Department of tertiary care centre Study Duration: 2 years (October 2018 to December 2020).Study population: All patients with cataract requiring surgery admitted in tertiary care center Sample Size: 700 Results: Majority of study subjects belongs to age group 41 -40 years contributing 511 cases (73%) followed by age group 65 yrs and more 133 (19%),16-40 age group 35 (5%) and 15 years or less 21 (3%) respectively. males contributing 390 cases (55.71%) followed by females 310 cases (44.29%).Male: Female ratio is 1.25: 1. preoperative visual acuity in operated eye is in the range of < 3 /60 - Perception to light (PLPR) in majority of subjects contributing 497 cases (71%) followed by 161 cases (23%) in between < 6/ 60 - 3 /60 group, 35 cases (5%) in < 6 /18 to 6 /60 group and 7 cases (1 %) in 6 /18 or better group respectively. most common intraoperative complication was posterior capsular rent contributing 19 cases (2.71%) followed by iris prolapse 14 cases (2%), premature entry 10(1.43%), Descemet's membrane stripping 10 (1.43%), intraoperative hyphaema 8 (1.14%), capsular extension in 7 cases(1%) Iridodialysis in 5 (0.71%) and zonular dialysis in 5(0.57%) respectively Conclusions: Rate of complication was higher in hypermature type of cataract .There was no statistical signicant association between age and intraoperative complications.
