The 90D slit lamp lens is the most popular power for non-contact fundus examinations.
It offers a wide-field fundus image out to and beyond the equator.
A 90D provides a greater field of view than a 78D lens.
This greater illuminated field area makes it ideal for scanning the lens capsule and beyond.
