Cutting-aspiration instruments are discussed in relation to design and principles of action. Experience with the Roto-extractor in over 100 cases is reviewed. Large pupillary openings were achieved in nearly all cases. No vitreous was attached to the wound postoperatively. Retinal detachment has not occurred to date in nontraumatic lenticular opacities.
本文讨论了切割抽吸器械的设计及作用原理。回顾了在100多例手术中使用旋转式取出器的经验。几乎所有病例都实现了大瞳孔开口。术后伤口处未发现玻璃体附着。迄今为止,非外伤性晶状体混浊患者未发生视网膜脱离。
