Clinicopathologic data to assist ophthalmologists in choosing a safe and efficacious anterior chamber intraocular lens (IOL) are rapidly becoming available. Two important factors that have led to an increased success rate with some anterior chamber IOL styles are (1) attention to lens design and (2) attention to modern manufacturing and lens finishing techniques. We now know much more about how to achieve appropriate lens flexibility, which decreases the need for perfect sizing. Increased attention has been given to the anterior-posterior vaulting characteristics of IOLs. This has reduced the incidence of various complications such as the intermittent touch syndrome and the uveal chafing syndrome. We recognize several design flaws in some lens styles. For example, there is now a considerable decrease in the number of small-diameter, round-looped anterior chamber IOLs being implanted, particularly those with a closed-loop configuration. Several problems have been and continue to be caused by some poorly manufactured anterior chamber lenses with sharp optic and haptic edges. Technology to assure smooth lens finishing and polishing is available and readily accessible to all manufacturers. Defective lenses should soon be a thing of the past.
有助于眼科医生选择安全有效的前房型人工晶状体(IOL)的临床病理数据正迅速可得。一些前房型IOL款式成功率提高的两个重要因素是:(1)关注晶状体设计;(2)关注现代制造和晶状体表面处理技术。我们现在对如何实现适当的晶状体柔韧性了解得更多了,这减少了对精确尺寸的需求。对IOL前后拱顶特征的关注度增加了。这降低了诸如间歇性接触综合征和葡萄膜摩擦综合征等各种并发症的发生率。我们认识到一些晶状体款式存在设计缺陷。例如,目前植入的小直径、圆形袢前房型IOL数量大幅减少,尤其是那些闭环构型的。一些制造工艺不佳、光学部和襻边缘锋利的前房型晶状体已经并将继续引发若干问题。确保晶状体表面光滑处理和抛光的技术是可用的,所有制造商都能轻易获得。有缺陷的晶状体应该很快成为历史。
