Successful surgical correction of a cataract in a chimpanzee (Pan troglodytes) via field setting at a zoological facility.

ABSTRACT

A 41-year-old male vasectomized, zoo-housed chimpanzee (Pan troglodytes) presented with progressive visual deficits due to bilateral cataract formation. Phacoemulsification and lenticular implant were performed by a veterinary and human board-certified ophthalmologist team in a field setting. Post-operative healing occurred without complication, and the patient returned to the troop with improved vision.
