In cataract surgery, capsulorhexis refers to which specific step?

Capsulorhexis is a crucial step in cataract surgery involving the careful excision or tearing of the anterior capsule of the lens. This step is essential for gaining access to the lens and creates a circular opening that facilitates the safe removal of the cataractous lens material. A well-performed capsulorhexis allows for proper placement of the intraocular lens afterward and contributes to the overall success of the surgery, ensuring that the integrity of the remaining capsule is maintained.

This specific technique requires skill as it must be done cautiously to prevent rupturing the posterior capsule, which could lead to complications. A precise capsulorhexis helps in minimizing potential risks during the surgery and ensures that the surgical field is adequately prepared for the subsequent steps, including the removal of the nucleus and cortex as well as the placement of the intraocular lens.
