要約
(EN)
A one-piece intraocular lens realizing adhesion of the intraocular lens to the inner surface of a capsule more advantageously by viscosity imparted to the intraocular lens, and being deployed more positively after it is inserted into the capsule and secured therein while being positioned at a specified location. The intraocular lens has an optical portion (12) and supporting portions (16, 16) that are formed integrally with a soft material exhibiting viscosity, wherein viscosity reducing portions (32, 32) having irregularities are formed on at least one-end faces of the supporting portions (16, 16) in the longitudinal direction.

本发明涉及一种通过赋予人工晶体的粘性更有利地实现人工晶体与囊内表面的粘附、并且在其插入囊内以及在特定位置定位固定后更主动地展开的一体式人工晶体。这种人工晶体具有由粘性软质材料一体成形的光学部(12)和支持部(16,16),其中,在支持部(16,16)前后方向的至少一个面上形成有具有凹凸物的降粘部分(32,32)。
