Cataract is the most common cause of blindness and cataract surgery is a common procedure. There is a need for a low cost, safe and effective form of cataract surgery for the developing world. This study reports the outcome of small incision cataract surgery in a developing country.
Eyes without coexisting ocular disease but with mature cataracts were operated upon. Small incision cataract surgery technique was used and patients were prospectively followed up. The procedure involved whole nucleus delivery through a sclerocorneal tunnel wound and insertion of a posterior chamber lens. Eyes examined at five days and six weeks after surgery are reported on for uncorrected visual acuity, complications of surgery and causes of poor outcome where applicable.
Seventy-one eyes were included in this study. Uncorrected visual acuity at five days postop was good in 31 (43.7%) eyes and 49 (69.0%) eyes after six weeks of surgery. Six weeks postop, four (5.6%) eyes had poor outcome. The most common intraoperative complication was rupture of the posterior capsule while retinal lesions were the most common cause of poor visual outcome.
Small incision cataract surgery offers faster visual recovery, is cost effective and has the prospects for increasing the uptake of cataract surgery in a developing country.
白内障是导致失明的最常见原因，白内障手术是一种常见的手术。发展中国家需要一种低成本、安全有效的白内障手术方式。本研究报告了一个发展中国家小切口白内障手术的结果。
对无并存眼病但患有成熟白内障的眼睛进行手术。采用小切口白内障手术技术，并对患者进行前瞻性随访。该手术包括通过巩膜隧道伤口娩出整个晶状体核并植入后房型人工晶状体。报告了术后五天和六周检查的眼睛的未矫正视力、手术并发症以及适用情况下预后不良的原因。
本研究纳入了71只眼睛。术后五天未矫正视力良好的有31只（43.7%）眼睛，术后六周有49只（69.0%）眼睛。术后六周，4只（5.6%）眼睛预后不良。最常见的术中并发症是后囊破裂，而视网膜病变是视力预后不良的最常见原因。
小切口白内障手术能使视力恢复更快，具有成本效益，并且有增加发展中国家白内障手术接受率的前景。
