The capsulorhexis procedure is a key part of cataract surgery. During capsulorhexis, a circular opening is torn into the lens capsule. For managing a circular tear, the medical literature details a set of instructions for the inexperienced surgeon. We have translated these instructions into a descriptive algorithm that simulates the behavior of the capsulorhexis tear. The lens capsule is modeled by a mass-spring mesh. To enable smooth tear propagation within the mesh, we adapted an algorithm originally developed for interactive cutting in triangulated surfaces that constantly re-triangulates around the tear end. The capsulorhexis procedure is implemented as a module for the ophthalmosurgical training simulator EYESI.
