Abstract : The need has existed for many years to automate the therapeutic process of placing laser-induced lesions on a patient's retina at specific locations while protecting the critical vision anatomy. Furthermore, it is desirable for the lesions to be of consistent and controllable size (diameter and/or depth). Partial solutions have been designed with varying degrees of success, but no system has yet been developed which can both track the moving eye at clinically acceptable speeds and control the lesion formation in real time. This dissertation describes research toward the development of a Computer Aided Laser Optics System for Ophthalmic Surgery (CALOSOS): a reliable, safe, cost-effective system which can control laser photocoagulators of the type found in an ophthalmologist's office. The system will safely create therapeutic retinal lesions of a specified number and location in minimal time with little or no human intervention.
