Abstract : The Phase 1 STTR technical effort demonstrated the safety and efficiency of a continuous wave (cw) diode pumped frequency doubled YAG laser for the treatment of glaucoma. In-vitro and in-vivo experiments were conducted to establish safety and to identify the procedures best suited for this laser. The laser was fabricated according to a design developed at the Air Force Phillips Laboratory. The most significant result of the work was the verification of the assumption that the cw diode pumped frequency doubled YAG laser effects a tissue response nearly identical to that observed with an argon ion laser at identical power, spot size, and pulse duration. In-vitro exposure of ocular tissue with both lasers showed an acute response consistent with a thermal process. The use of the frequency doubled YAG laser to treat retinal tissue and for laser suturelysis was also investigated. These additional tests extend the potential of the laser to encompass all ophthalmic applications currently performed with the argon ion laser.
