Significant advances in retinal surgery have been achieved through developments in the fields of photocoagulation and electrosurgery. Unresolved problems, however, are posed by the inherent nature of these techniques. Lesions of high reflectivity or those located in the extreme periphery and optical inhomogeneities serve as limitations on the role of photocoagulation. The inconsistencies of spark gap equipment and the variables of tissue reaction resulting from inadequate control of fluid at the point of electrical contact are problems associated with most electrosurgical devices. Furthermore, treatment with this equipment also involves relatively nonselective destruction of tissue.Technologic achievements, as represented by optical masers and fiber optics, offer at least the potential of a solution to some of the problems encountered clinically. This report will describe the theoretical basis for a fiber laser, the experimental evaluation of that concept, and finally will indicate some clinical applications.
