Designed with a large diameter optic to view/treat structures of the peripheral iris. Larger diameter magnifying optic has a wider view than existing lens designs and offers great latitude in therapy positioning. Image magnification 1.6x and laser spot magnification 0.63x. Outstanding optics with no chance of the lens button detaching. Optimized optic to allow for laser placement under the lid to reduce appearance of a ghost image. Lenses have a custom evaporated diamond coating and can be used with the appropriate therapeutic lasers. An ultralight aluminum alloy rim with a black "Sure Grip" ring makes each lens ergonomically friendly. Sold individually.
