A 32-year-old captive female Chilean flamingo (Phoenicopterus chilensis) was diagnosed with a hypermature resorbed cataract in the right eye and a mature cataract with phacolytic uveitis in the left eye. No other systemic or neurologic physical abnormalities were detected. The patient was considered blind from bilateral cataracts, and with a reduced quality of life, surgery was indicated to remove the mature cataract in the left eye. Before surgery, the phacolytic uveitis was treated in the left eye for 1 week with topical and systemic anti-inflammatory and antibiotic medication. Unilateral phacoemulsification was performed on the left eye while under general anesthesia. The individual recovered uneventfully and regained vision in the left eye. The bird was returned to its enclosure 8 days after the surgical procedure. No abnormalities were noted in behavior or reintegration. Three weeks after the phacoemulsification was performed in the left eye, the individual presented with active uveitis, without vision loss, suspected secondary to incisional infection, which was managed with topical and systemic anti-inflammatory and antibiotic medication. At day 41 the patient was discharged with no disease conditions affecting the left eye, and the flamingo's vision was considered significantly improved compared with initial presentation. Phacoemulsification was safe and effective in removing the lens, resolving phacolytic uveitis, and restoring vision in spite of the postsurgical incisional infection. Some adaptations in the surgical approach and medical management are recommended on the basis of morphology, feeding habits, and behavior of this aquatic avian species to avoid postsurgical incisional infection and uveitis.
