Bilateral Phacoemulsification in an African Elephant (Loxodonta africana)

Figure 13

A corrective contact lens (+ 9.00 diopters) has been placed in the elephant’s right eye in an attempt to correct the marked hyperopia due to his being left aphakic (Acrivet, Veterinary Division of S&V Technologies AG, Hennigsdorf, Germany). Note the smaller circular area within the center of the lens (this is most readily visible along the ventromedial pupil extending from approximately 2:30 to 9:00 o’clock) that represents the corrective portion of the lens. The four black dots at the 12, 3, 6, and 9 o’clock edges of the corrective contact lens are to make it easier to visualize during subsequent examinations.
