Manual Capsulorhexis

Abstract

Continuous curvilinear capsulorhexis (also referred to as the rhexis) is performed by creating an aperture in the anterior capsule. The most common manual technique is made by initially puncturing the capsule surface, creating a capsule flap that is then dragged circumferentially to create a central, circular aperture. Experienced surgeons can perform a capsulorhexis quickly, adapting intraocular movements and adjusting the direction of the tearing force to create an ideal rhexis aperture (well centred and of a size that is small enough to just overlap the lens optic). Mimicking the proficient, rapid movements of expert surgeons may be daunting for Trainees who may not appreciate the sequence of movements that are required. However, once the technique broken down into steps, these movements become simple and reproducible. It should be acknowledged that novice surgeons will not always achieve a rhexis that is well centred and of perfect size or shape. Indeed, in everyday practice, capsulorhexis perfection is something all cataract surgeons strive for.
