Paper Abstract

To become highly proficient at a given surgical procedure and to reduce risk to patients, physicians must gain experience through a number means. Today optical training devices based on the actual surgical device coupled with computer models can provide the required realism to provide highly effective training. This paper presents a optical system that will be used for training residents to perform panretinal photocoagulation (PRP), a laser surgical procedure for treating the retina. The system will naturally evolve into a computer-assisted device for performing PRP. With the system described herein, simulations are created in the Umbra modeling and simulation framework. The simulation is composed of four building blocks: Pre-operation planning, multi-modality image registration, tracking the patient's eye movement, and positioning the laser according to the pre-planned aim points. A prototype simulation was developed to demonstrate a realistic depiction of the PRP the procedure. The ultimate goal of this project is to integrate the software into an existing ophthalmic device to increase the accuracy of the laser application procedure by providing computer-assisted surgery.
