Comparative Evaluation of Corneal versus Limbal Approach for Lens Extracapsular Extraction for Cataract Management-A Study of 20 Dogs

Twenty dogs were presented and diagnosed with cataract. The animals were divided into two groups, irrespective of sex, breed and age but animal temperament and keeper’s willingness for surgery were considered. In Group I and Group II, extracapsular extraction of lens through ‘Corneal approach’ and ‘Limbal approach’ was carried out. The surgical procedure was easier and less time consuming in Group I than in Group II moreover, post-operative complications viz. ocular discharge, irritation, blepharospasm and conjunctival inflammation were seen in both groups during the first week. However, opacity of cornea was the most frequent post-operative complication of cataract surgery by corneal incision technique. The success rates in respect of return of vision after cataract extraction by corneal and limbal incision techniques were 66.66 and 83.33 percent respectively.
