The Katena Single-use Retina 90 Lens offers a 1.0x magnified view of the retina within the region of the arcades. It is primarily designed to facilitate the diagnosis and treatment of diabetic eye disease and age-related macular degeneration (ARMD).
This lens offers a view that is both detailed and wide-field allowing visualization and treatment without the need to calculate the magnification change to the image, optic nerve or laser spot size. This lens has a custom anti-reflective coating and can be used with all lasers.
The Retina 90 lens has an image magnification of 1.0x which produces a laser spot magnification of 1.0x. The field of view is 90° when static and 120° if used dynamically.
