Abstract

We designed a glass and polyimide iris-plane, iris-clip intraocular lens. It is sterilized in the autoclave and weighs approximately 6 mg in water. The optic is 0.3 mm thick for a 19-diopter lens and the flexible haptic is 0.05 mm thick. Two identical haptics and the optic are joined mechanically to form the intraocular lens. The round spatula-like portion of an insertional instrument secures the intraocular lens by passing through two opposing flexible haptic loops and behind the optic. Fluid or air is irrigated through the cannula as the implant is inserted in order to protect the endothelium.

摘要

我们设计了一种玻璃和聚酰亚胺材质的虹膜平面、虹膜夹式人工晶状体。它在高压灭菌器中进行消毒，在水中的重量约为6毫克。对于一个19屈光度的晶状体，光学部厚度为0.3毫米，柔性触觉部厚度为0.05毫米。两个相同的触觉部和光学部通过机械方式连接以形成人工晶状体。插入器械的圆形刮刀状部分通过两个相对的柔性触觉环并在光学部后方穿过，从而固定人工晶状体。在植入人工晶状体时，通过套管冲洗液体或空气，以保护内皮细胞。
