capsulorrhexis
Pronunciation: cap-soo-lor-EX-is
Surgical technique creating a circular opening in the anterior lens capsule during cataract surgery. Critical step for safe lens removal and IOL placement.
Full Definition
A precise surgical maneuver performed during cataract surgery that involves creating a controlled, circular tear in the anterior lens capsule using specialized forceps or a cystotome. The size and centration of the capsulorrhexis are critical for successful surgery, typically measuring 5.0-5.5mm in diameter. A well-executed capsulorrhexis provides access for lens removal while maintaining capsular bag integrity for IOL placement. Poor capsulorrhexis technique can lead to complications including capsular tears, lens instability, or suboptimal visual outcomes.
Usage
Usage note: Often abbreviated as CCC; always describe size and quality in surgical documentation.
