Capsulorhexis is a surgical procedure used in ophthalmology. It involves creating a circular opening in the lens capsule to remove the cataract and replace it with an artificial lens. Synonyms for this word include Capsulotomy, Capsulectomy, Capsulotomy-Rhexis, and Capsulorhexesis. Capsulotomy is a general term for any opening made in the capsule, while Capsulectomy involves removal of the entire capsule. Capsulorhexesis refers to the creation of a tear in the capsule with careful manipulation, whereas Capsulotomy-Rhexis combines the two previous techniques. These synonyms may be used interchangeably in medical texts and depending on the preferred technique of the surgeon.
