Evaluation of a KTP (potassium-titanyl-phosphate) 532 nm laser for endovaporization of choroidal melanomas.

Background And Objectives: The purpose of this in vitro study is to evaluate the use of the KTP (potassium-titanyl-phosphate) 532 nm laser for future use in endovaporization of large choroidal melanomas.

Study Design/materials And Methods: A KTP 532 nm green laser coupled to a 0.3 mm fiberoptic probe was used to perform in vitro studies on human cadaver eyes and on one enucleated melanoma eye.
