    • The compound intraocular lens ("CIOL") of the present invention includes a preexisting lens within the eye (which can be either of the crystalline lens of the eye, a conventional IOL or a base lens of a multi-component IOL) used as a platform for support (i.e., the "support lens") a cap situated on the support lens, and a sandwich lens which is sandwiched between the support lens and the cap lens. Utilizing a pre-existing implanted IOL or the crystalline lens of the eye, a surgeon can modify a patient's vision characteristics merely by utilizing the cap and sandwich lenses in conjunction with the pre-existing implanted IOL or the crystalline lens of the eye. The CIOL has several enhanced features: (1) it can be configured as a monofocal, multi-focal, tri-focal or bifocal optical system; (2) it can be configured to correct astigmatism, if desired; (3) it can be comprised of ultraviolet light-absorbing material; (4) it can be comprised of tinted materials if desired; and (5) the components may be comprised of chemically-treated materials to decrease their cellular reactivity.
    • 本发明的复合眼内透镜(“CIOL”)包括眼睛内的预先存在的透镜(其可以是眼睛的晶状体,常规IOL或多组分IOL的基础透镜中的任一种),其被用作 用于支撑(即,“支撑透镜”)的平台,位于支撑透镜上的盖子和夹在支撑透镜和盖透镜之间的夹心透镜。 使用预先存在的IOL或眼晶体,外科医生可以仅通过利用盖和夹心透镜与预先存在的植入的IOL或眼晶体相结合来修改患者的视力特征。 CIOL具有几项增强功能:(1)可配置为单焦点,多焦点,三焦或双焦光学系统; (2)如果需要,可以将其配置为矫正散光; (3)可以由紫外光吸收材料构成; (4)如果需要,它可以由有色材料组成; 和(5)组分可以由化学处理的材料组成以降低它们的细胞反应性。
