人工晶体植入术已有近30年的历史。近15年来人工晶体的应用已得到广泛的采用,并在眼科界普遍推广,今天人工晶体已从前房型发展为后房型。因为实践证明,后房型人工晶体的并发症少,视力预后好。笔者在美国曾观察总结了人工晶体植入的利弊。本文目的在于估价后房型人工晶体植入术的并发症和视力预后,并与单纯白内障囊外摘除术作比较。对象和方法美国太平洋医学中心眼科自1977年7月至1983年6月共作白内障手术653例804眼,其中老年性白内障358例416眼;作后房型人 IOL implantation for nearly 30 years of history. The application of intraocular lens in the past 15 years has been widely adopted and widely popularized in ophthalmology. Today, intraocular lenses have been developed from anterior chamber to posterior chamber. Because the practice proved that posterior chamber intraocular lens less complications, good vision prognosis. I have observed in the United States summarized the pros and cons of intraocular lens implantation. The purpose of this article is to evaluate the complications and visual acuity prognosis of posterior chamber intraocular lens implantation compared with simple extracapsular cataract extraction. Subjects and Methods The American Academy of Pacific Medical Center ophthalmology from July 1977 to June 1983 a total of 653 cases of cataract surgery 804 eyes, of which 358 cases of age-related cataract 416 eyes; for posterior chamber type
