*Dr. Caccamise has very generously shared his images of patients taken while operating during the "eye season" in rural India as well as those from his private practice during the 1960's and 1970's. Many of his images are significant for their historical perspective and for techniques and conditions seen in settings in undeveloped areas.

Subluxated, couched lens

subluxated, couched lens/cataract

The coucher subluxated the immature nuclear cataract nasally. The temporal portion of the pupil area that is black is the area free of the lens/cataract. In successful couching, the pupil is completely black and the cataractous lens is seen lying on the floor of the vitreous chamber. The couch mark was made approximately 3-4 mms from the limbus at 7:30 to 8:00 o'clock.It is seen vaguely as a dark line concentric with the limbus - blood and hyperemia make it difficult to detect.
