Silverstone, the most powerful tool yet for examining the retina, is the only ultra-widefield imaging device with integrated swept-source OCT. Silverstone produces a 200° single-capture retinal image of unrivaled clarity in less than ½ second and enables optomap-guided OCT scanning across the retina and into the far periphery.
Silverstone offers the following benefits:
