NIDEK GYC-500 / GYC-500 Vixi green
The GYC-500 is NIDEK's compact 532 nm green photocoagulator for retinal and macular treatment, iridotomy and trabeculoplasty. A diode pumped solid state laser in a small console feeds a fibre to a slit lamp, indirect ophthalmoscope, endophotocoagulation or YAG combination delivery unit. With a scan delivery unit it becomes the GYC-500 Vixi, which fires preset multi spot patterns and can step automatically to the next treatment region.
