Phacofragmentation and Aspiration in Canine Mature Cataract: Surgical technique, Success rate and Complications

Abstract

Phacofragmentation and aspiration technique without intraocular lens implantation was reported in 26 mature cataractous dogs. Dogs included in this study were 13 Poodles, 6 crossbred dogs, 4 Cocker spaniels, 1 Shih-tzu, 1 West Highland white terrier and 1 Miniature pinscher. All dogs were clinically blinded from bilateral mature cataracts with positive dazzle reflex prior to the surgery. 24 dogs (92.31%) regained vision after the surgery which remained until the end of the study. Vitreous degeneration was found pre-operatively in one dog. Hyphema, displacement of lens into vitreous chamber, rupture of the posterior lens capsule and miosis were found intra-operatively in 1, 1, 2 and 2 dogs, respectively. Corneal edema, corneal ulcer, glaucoma, uveitis, posterior capsule opacification, posterior synechia and fibrin formation were evident post-operatively in 2, 1, 1, 26, 13, 9 and 7 dogs, respectively.
