Extracapsular cataract extraction with intraocular lens implantation in dogs

A clinical study on extracapsular cataract extraction with intraocular polymethyl-methacrylate lens (41 D, 6.5 mm optic and 17 mm haptic) implantation was done on 14 eyes of 13 dogs with mature cataract, under propofol (5 mg/kg, i.v.) anaesthesia. Cataract surgery was done using coaxial operating microscope (OM-8, Takagi, Japan). After 3 months of cataract surgery, restoration of ambulatory vision was graded “good” in 57% cases followed by ‘fair’ in 29% cases and ‘failure’ in 14% cases. Intraoperative complications observed were chemosis (2 cases), iris bulging (2 cases) and haemorrhage (1 case) which were managed during surgery. Postoperative complications included corneal opacity (4 cases), corneal oedema (3 cases), posterior capsular opacity (1 case) and uveitis (1 case) which were corrected using topical antibiotic-steroid combinations, NSAIDs and mydriatics.
