Population-baed aement of the outcome of cataract urgery in an urban population in outhern India Original Reearch Article

PURPOE: To ae the outcome of cataract urgery in an urban population in outhern India. METHOD: A part of a population-baed cro-ectional epidemiologic tudy, the Andhra Pradeh Eye Dieae tudy, 2,522 people of all age, including 1,399 individual 30 year of age or older, from 24 cluter repreentative of the population of Hyderabad in outhern India underwent a detailed interview and ocular evaluation including logarithm of minimal angle of reolution (logMAR) viual acuity, refraction, lit-lamp biomicrocopy, applanation tonometry, goniocopy, dilation, cataract grading, aphakia/peudophakia tatu, and tereocopic fundu evaluation. Automated threhold viual field and lit-lamp and fundu photography were performed when indicated by tandardized criteria. Very poor outcome in an eye that had undergone cataract urgery wa defined a preenting ditance viual acuity wore than 20/200, and poor outcome wa defined a viual acuity wore than 20/60 to 20/200. REULT: In ubject 50 year of age or older, after adjutment for age and ex ditribution, the rate of having had cataract urgery in one or both eye wa 14.6% (95% confidence interval [CI], 11.4% to 17.8%). Of 131 eye (91 ubject) that had undergone cataract urgery, 28 (21.4%; 95% CI, 14.4% to 28.4%) had very poor outcome and another 40 (30.5%; 95% CI, 22.6% to 38.4%) had poor outcome. The very poor outcome in 20 (71.4%) of 28 eye and poor outcome in 23 (57.5%) of 40 eye could be attributed to urgery-related caue or inadequate refractive correction. With multivariate analyi, very poor outcome a a reult of urgery-related caue or inadequate refractive correction wa more likely to be aociated with intracapular cataract extraction than with extracapular cataract extraction (odd ratio, 9.34; 95% CI, 2.49 to 35.06) in ubject belonging to the lowet ocioeconomic tatu (odd ratio, 4.92; 95% CI, 1.16 to 20.93) and with date of urgery 3 or fewer year before the urvey than with more than 3 year (odd ratio, 4.52; 95% CI, 1.33 to 15.39). Alo, very poor or poor outcome a a reult of urgery-related caue or inadequate refractive correction wa aociated with women (odd ratio, 2.55; 95% CI, 1.06 to 6.16). CONCLUION: The very high rate of very poor and poor viual outcome, predominantly a a reult of urgery-related caue and inadequate refractive correction, in thi urban population of India ugget that more attention i needed to improve the viual outcome of cataract urgery. In order to deal with cataract-related viual impairment in India, a much emphai on urgical quality, refractive correction, and follow-up care i neceary a on the number of urgerie.
