30多年来,眼科医师在致力于人工晶体植入的研究。近10年来,人工晶体在设计及制作工艺上进行了不断地改革,取得了发展。植入的手术技术和白内障囊内、囊外摘出技术也更趋精细。又人工晶体固定问题的基本解决和手术后并发症的减少,使其逐渐得到推广。后房型人工晶体是近年来才又发展起来的。现就有关这方面的进展综述如下。一、概况第一枚后房型人工晶体是Ridley于1949年11月对一位白内障患者在囊外摘出术后移植的,这是一个双凸型的聚甲基丙烯酸甲酯(PMMA)晶体,直径8.35mm,比正常人体的晶体小1.1mm。以便容易植入,避免过度压迫睫状体。1950年又进行了第2例同样植入术。以后Arruga、Bink- For over 30 years, ophthalmologists have been working on the implantation of artificial lenses. In the past 10 years, the artificial crystal has been continuously reforming in the design and production process and has made development. Implanted surgical techniques and cataract capsule, extracapsular extraction techniques are more sophisticated. And the basic solution to the problem of intraocular lens fixation and reduction of postoperative complications, so that it has been gradually promoted. Posterior chamber intraocular lens is only developed in recent years. The progress made in this respect is summarized below. I. Overview The first posterior chamber intraocular lens (IOL) was Ridley’s transplanted extracapsular cataract patient in November 1949, a biconvex polymethylmethacrylate (PMMA) crystal with a diameter 8.35mm, 1.1mm smaller than that of a normal human body. In order to facilitate implantation, to avoid over-oppression of the ciliary body. The second case of the same implant was performed in 1950. After Arruga, Bink-
