Abstract
Phacoemulsification (PEA) was applied in two canine cases suffering from juvenile cataract of both eyes. Case 1 was one-year-old, female, mongrel dog with complaints of cataract and its related visual disturbance. Case 2 was 7 month-old, male, American cocker spaniel with the same complaints as in the case 1. In case 1, lenses of both eyes were removed with PEA. The prognosis was good. In case 2, lenses of the both eyes were also removed by the method of PEA, and an intraocular lens was implanted in the left eye. However, severe uveitis and ocular hypertension were found in the lens-implanted eye after the cataract surgery. Surgical treatment with filtering procedures and iridectomy were carried out, since intraocular pressure could not be regulated by the medical therapy. The case was also treated with steroids to control uveitis, though corneal opacity was not entirely restored. Careful manegements including surgical proceudures were needed on the cataract surgery.
