Abstract:

The program achievements were as follows - A diode pumped frequency doubled NdYAG laser system with adapters for commercial slit lamps was developed with the desired portability. The laser unit had a footprint of about 10 x 14 and weighed less than 20 kg. The frequency doubled NdYAG laser operating at 532 nm had substantially the same efficacy as the large Argon ion laser operating at 514 nm. The NdYAG laser achieved equivalent treatments as the Argon ion laser, at slightly lower power levels - Successful clinical trials were performed for the treatment of glaucoma and for one type of retinal disease. However, the number of patients treated was quite small. Full results are given in the report. - The lasers used in the clinical trials were similar to the commercial units co-developed by our associates in Europe. The original technology transferred in Phase I, based on work done at the Air Force Research Laboratorys Phillips Research Site in Albuquerque NM formerly Phillips Laboratory, was not directly used in the clinical units because significant thermal problems were found when the Phase I laser was enclosed to develop a commercial-style clinical laser unit.
