The author's preferred technique for extracapsular cataract extraction with insertion of a posterior chamber intraocular lens implant is described. Although automated devices are not available and are unattractive to many ophthalmologists, the author finds such equipment provides the safest means of making the conversion from intracapsular to extracapsular cataract extraction. In the planned extracapsular cataract extraction, a "beer can" anterior capsulotomy is performed and the nucleus is removed as described. The residual lens cortical material is aspirated using the Cavitron machine. The Cavitron machine is also used for phacoemulsification which is performed in the posterior chamber. A Shearing type posterior chamber lens is used when indicated. A primary posterior capsulotomy is performed routinely. An analysis of the first 800 such procedures is made with each case being examined 11-14 months postoperatively. Compared to intracapsular cataract extraction with an intraocular lens, the results are favourable, especially regarding the rate of cystoid macular edema, retinal detachment, and corneal edema.
本文描述了作者所青睐的囊外白内障摘除联合后房型人工晶状体植入术的技术。尽管自动化设备并不普及，且对许多眼科医生缺乏吸引力，但作者发现此类设备为从囊内白内障摘除术转换为囊外白内障摘除术提供了最安全的方法。在计划进行的囊外白内障摘除术中，行“啤酒罐”式前囊切开术，并按所述方法取出晶状体核。使用Cavitron机器吸出残留的晶状体皮质物质。Cavitron机器也用于后房型的超声乳化术。必要时使用剪切型后房型人工晶状体。常规进行一期后囊切开术。对最初的800例此类手术进行了分析，每例均在术后11至14个月进行检查。与囊内白内障摘除联合人工晶状体植入术相比，结果是有利的，尤其是在黄斑囊样水肿、视网膜脱离和角膜水肿的发生率方面。
