Capsulorhexis surgery simulation

Cataract surgery consists of several parts, the most important and the first part of which is Capsulorhexis, which is our main focus in this project. Capsulorhexis is a procedure that a suitable tool cuts the shell around the lens (Capsul) in a circle to reach the lens and empty it. Successful performance of anterior capsulotomy is one of the most vital steps for optimal cataract surgery results, which ensures postoperative stable intraocular lens (IOL) and reduces the risk of capsular tears. The ideal anterior capsulotomy is round, continuous, well-centered, and overlaps the implanted IOL around its circumference. The absence of any mentioned factors can result in impedance to desired surgical and visual outcomes. In order to develop a suitable environment for cataract surgery training, various operations such as cutting, suction, and tissue removal are developed. First, we need to build a mechanical model of the eye according to the parameters of the actual eye. This model consists of three parts: 3D geometry model, physical model, and visual model. Different parts, such as the cornea, sclera, or lens, have different materials, so this simulation provides a mechanical model that can be implemented in the simulation, which includes the material of each tissue (softness and hardness) and how the tissue interacts with the tool. We use the SOFA framework to perform dynamic calculations. SOFA is an open-source framework targeting real-time simulation, emphasizing medical simulation.
