Abstract
Background:Cataract is a common disease in the lenses of birds. Cataract surgery is the recommended treatment for birds with visual impairment. Nevertheless, reports of the results of cataract surgery in birds are limited.Case Description:An unknown-aged male black kite (Milvus migrans) was presented to Kasetsart University Veterinary Teaching Hospital to evaluate and treat bilateral ocular cloudiness. Bilateral hypermature cataracts were diagnosed. A-scan biometry was carried out to calculate the intraocular lens’ (IOL) diopter power. Bilateral cataract extraction by lens aspiration with +17.5 diopter foldable IOL implantation was successfully completed. Two months after surgery, the black kite navigated well and could fly and catch his food. Retinoscopy at 4 months postoperative revealed −0.5 diopters OD, whereas OS could not be assessed due to a poor reflection. Follow-up at 3 years after surgery, the black kite’s vision remained favorable.Conclusion:Phacoemulsification and IOL implantation were successful in this black kite because the black kite’s vision was noticeably improved, and the black kite was able to navigate well. To the authors’ knowledge, this is the first report of bilateral cataract surgery with IOL implantation using a calculated dioptric power (+17.5 D) IOL in a black kite.
