目的 评估印度南部农村地区白内障手术的临床效果。 方法 采用整群抽样的方法，随机抽取 50 岁以上人群的横断面样本，于 1999 年进行视力测量、验光和眼科检查。询问受试者每只白内障手术眼的手术日期和地点。记录了视力低于 6/18 的眼睛的手术并发症，并确定了视力下降的主要原因。 结果 在 682 名白内障手术者样本中，13.8% 的双眼视力低于 6/60，25.2% 的双眼视力好于或等于 6/18，37.8% 的人进行了双眼手术。对于无晶状体眼，50.5%的患者视力优于或等于6/18；最佳校正率为 82.6%。对于人工晶状体眼，相应的百分比为78.0%和94.5%。超过三分之一的眼睛患有人工晶状体眼，近四分之三的眼睛是在非政府机构进行的手术。未矫正的无晶状体眼和其他屈光不正是视力障碍的主要原因。在多元逻辑回归模型中，无晶状体眼的视力不佳与文盲、农村居住和政府机构的手术有关；性别和手术时间并不是视力结果的预测因素。这些变量均与无晶状体眼的最佳矫正结果无关，也与人工晶状体眼的呈现和最佳矫正结果无关。 结论 人工晶状体眼的视力结果良好。必须更多地关注白内障手术者中由于无晶状体矫正不充分而造成的不必要的视力损伤，特别是在政府机构中进行手术的人、文盲和生活在农村的人。
PURPOSE To assess the clinical outcomes of cataract surgery in rural southern India.METHODS Cluster sampling was used in randomly selecting a cross-sectional sample of persons 50 years of age or older for visual acuity measurement, refraction, and ocular examination in 1999. Subjects were queried as to the date and place of surgery for each cataract-operated eye. Surgical complications were noted and the principal cause of reduced vision was identified for eyes with presenting visual acuity worse than 6/18.RESULTS Within the cataract-operated sample of 682 persons, 13.8% had presenting visual acuity worse than 6/60 in both eyes, 25.2% better than or equal to 6/18 in both eyes, and 37.8% were bilaterally operated on. For aphakic eyes, 50.5% presented with visual acuity better than or equal to 6/18; 82.6% with best-correction. For pseudophakic eyes, the corresponding percentages were 78.0% and 94.5%. Over one-third of all eyes were pseudophakic, and nearly three-fourths had been operated on in non-governmental facilities. Uncorrected aphakia and other refractive error were the main causes of vision impairment. In multiple logistic regression modeling, poor presenting visual acuity in aphakic eyes was associated with illiteracy, rural residence, and surgery in government facilities; gender and time period of surgery were not predictors of vision outcomes. None of these variables were associated with best-corrected outcomes in aphakic eyes, nor with presenting and best-corrected outcomes in pseudophakic eyes.CONCLUSIONS Visual acuity outcomes in pseudophakic eyes were good. More attention must be given to needless vision impairment among the cataract-operated because of inadequate aphakic correction, especially among those operated on in government facilities, the illiterate, and those living in rural villages.
