Design and development of a computer-assisted retinal laser surgery system

Since the mid-1980s, the development of a therapeutic, computer-assisted laser photocoagulation system to treat retinal disorders has progressed under the guidance of Dr. Welch, the Marion E. Forsman Centennial Professor of Engineering, Department of Biomedical Engineering, the University of Texas at Austin. This paper reviews the development of the system, related research in eye movement and laser-tissue interaction, and system implementation and testing. While subsets of these topics have been reported in prior publications, this paper brings the entire evolutionary design of the system together. We also discuss other recent "spinoff" uses of the system technology that have not been reported elsewhere and describe the impact of the latest technical advances on the overall system design.
