We performed a prospective fluorescein angiographic study on 66 patients who had undergone extracapsular cataract extractions with implantation of a Shearing posterior chamber intraocular lens. A primary posterior capsulotomy was performed in every case. The eyes were studied 11 to 23 months postoperatively. The incidence of cystoid macular edema (3%) was lower than that found in three series of cataract extractions previously reported. Extracapsular cataract extraction with either (1) a Shearing posterior chamber intraocular lens and a primary posterior capsulotomy or (2) a Binkhorst intraocular lens and an intact posterior capsule produces a lower rate of cystoid macular edema than does intracapsular cataract extraction either with a Binkhorst intraocular lens or without an intraocular lens. There was no significant difference in the incidence of cystoid macular edema in the two extracapsular series, indicating that preservation of an intact posterior capsule was not a significant factor.
我们对66例接受了囊外白内障摘除术并植入了Shearing后房型人工晶状体的患者进行了一项前瞻性荧光素血管造影研究。每例均进行了一期后囊切开术。术后11至23个月对这些眼睛进行了研究。黄斑囊样水肿的发生率（3%）低于先前报道的三组白内障摘除术的发生率。与囊内白内障摘除术（无论是否植入Binkhorst人工晶状体）相比，（1）植入Shearing后房型人工晶状体并进行一期后囊切开术或（2）植入Binkhorst人工晶状体且后囊完整的囊外白内障摘除术导致黄斑囊样水肿的发生率较低。两个囊外系列中黄斑囊样水肿的发生率没有显著差异，这表明保留完整的后囊不是一个重要因素。
