Phacoemulsification in a clouded leopard (Neofelis nebulosa).

Phacoemulsification and prophylactic retinopexy were performed on a 3-month-old hand-raised clouded leopard with a unilateral mature cataract. The same procedures were repeated 3 months later when a cataract developed in the fellow eye. Examination procedures, anesthetic protocols, and surgical techniques were similar to those utilized in domestic cats. The patient retains highly functional aphakic vision at the present age of 2.5 years. An inherited basis for the cataracts is proposed. Although the cub was hand raised, the cataracts were unlike nutritional cataracts reported previously in domestic cats and dogs. To the author's knowledge this is the first report of cataract formation and phacoemulsification in a clouded leopard.
