Cataract is the most popular cause of blindness. This study addresses some aspects of cataract surgery in an Iranian population.
A cross-sectional study.
3000 adults over 50 in Varamin district.
Cataract surgical coverage was defined as the proportion of (pseudo) aphakic eyes of all operable and operated eyes with cataract. If there was obvious lens opacity in either or both eyes in combination with best corrected visual acuity less than 6/18, the person was asked why the operation for cataract was not done to find out about barriers of cataract surgery. Outcomes of cataract surgery were categorized as good, intermediate and poor using presenting visual acuity which were defined as visual acuity ≥ 6/18, 6/60 ≤ visual acuity < 6/18 and visual acuity < 6/60, respectively.
Cataract surgical coverage, barriers and outcomes of cataract surgery.
Out of 5638 examined eyes, 526 eyes (9.3%) had history of cataract surgery. 156 subjects (45.7%) had a unilateral and 185 subjects (54.2%) had bilateral operated eyes. Cataract surgical coverage was 66.4% in visually impaired eyes (visual acuity < 6/18), 90.4% in blind eyes (visual acuity < 3/60), 80.5% in visually impaired persons and 97.6% in blind persons. Cataract surgery in the majority of eyes (71.9%) had a good visual outcome. The main barrier of cataract surgery was unawareness of treatment.
Overall, the cataract services in the studied population were acceptable, although it should be improved, to achieve vision 2020 objectives.
白内障是导致失明的最常见原因。本研究探讨了伊朗人群白内障手术的一些方面。
横断面研究。
Varamin地区3000名50岁以上的成年人。
白内障手术覆盖率定义为所有可手术和已接受白内障手术眼睛中（假）无晶状体眼的比例。如果一只或两只眼睛存在明显的晶状体混浊且最佳矫正视力低于6/18，则询问该人为何未进行白内障手术以找出白内障手术的障碍。白内障手术的结果根据就诊时的视力分为良好、中等和差，分别定义为视力≥6/18、6/60≤视力<6/18和视力<6/60。
白内障手术覆盖率、白内障手术的障碍和结果。
在5638只受检眼中，526只眼（9.3%）有白内障手术史。156名受试者（45.7%）为单眼手术，185名受试者（54.2%）为双眼手术。视力受损眼（视力<6/18）的白内障手术覆盖率为66.4%，盲眼（视力<3/60）为90.4%，视力受损者为80.5%，盲人则为97.6%。大多数眼睛（71.9%）的白内障手术视觉效果良好。白内障手术的主要障碍是对治疗缺乏认识。
总体而言，尽管为实现“视觉2020”目标仍需改进，但研究人群中的白内障服务尚可接受。
