Cataracts are the most frequent cause of blindness in dogs which are characterised by a focal or diffused opacity of lens or lens capsule. Present clinical study was conducted on 12 dogs suffering from cataract. After the detailed ophthalmic and ultrasonographic examination, 7 (9 eyes) out of 12 dogs were surgically treated by extracapsular lens extraction method using operating microscope. The return of ambulatory vision was observed in 6 eyes out of 9 operated eyes and failure of vision was noted in 3 eyes. Peri-operative complications such as haemorrhage, meiosis and iris prolapse and post-operative complications such as posterior capsule opacity, suture breakage and glaucoma were reported. Higher incidence of cataract was noted in German shepherd (33.33%) followed by Pomeranian (25%), Cocker spaniel (16.67%), Mongrel (16.67%) and Spitz (8.33%). In this study it was found that extracapsular cataract extraction under general anesthesia along with retrobulbar nerve block is proved to be an effective method to treat the cataract.
