A continuous curvilinear capsulorhexis (CCC) provides a tear-resistant opening that allows use of a technique of capturing the intraocular lens (IOL) optic through the capsulorhexis opening when the opening is at least 1.0 to 2.0 mm smaller than the optic diameter. The technique provides stability and long-term centration of the IOL and prevents vitreous from extending anterior to the IOL. This paper reviews the current variations of optic capture including (1) haptics in the sulcus and IOL optic capture through a CCC, (2) haptics in the sulcus and IOL optic capture through an anterior capsule opening and a posterior CCC (PCCC), (3) haptics in the capsular bag and IOL optic capture through a PCCC, (4) haptics in the capsular bag and IOL optic capture through an anterior CCC, (5) haptics in the sulcus and IOL capture through a capsular membrane opening, and (6) haptics posterior to the capsular bag and IOL capture through a capsular membrane opening.
连续环形撕囊（CCC）可提供一个抗撕裂的开口，当该开口比人工晶状体（IOL）光学部直径至少小1.0至2.0毫米时，允许采用一种通过撕囊开口捕获IOL光学部的技术。该技术可提供IOL的稳定性和长期居中性，并防止玻璃体向前延伸至IOL前方。本文综述了当前光学部捕获的不同方法，包括：（1）襻位于睫状沟且通过CCC捕获IOL光学部；（2）襻位于睫状沟且通过前囊开口和后CCC（PCCC）捕获IOL光学部；（3）襻位于囊袋内且通过PCCC捕获IOL光学部；（4）襻位于囊袋内且通过前CCC捕获IOL光学部；（5）襻位于睫状沟且通过囊膜开口捕获IOL；（6）襻位于囊袋后方且通过囊膜开口捕获IOL。
