ABSTRACT

The clinical study was conducted on 22 eyes of 18 dogs (16 male and 2 female)to evaluate efficacy of Phacoemulsification for cataract removal and feasibility of rigid and foldable intraocular lens(+41 D) implantation in dogs. Animlas were operated under general anaesthesia using diazepam @ 0.5mg/kg b.wt and ketamine @ 5mg/kg b.wt combination and maintained on isoflurane inhalation anaesthesia. Animals were divided in two groups. In group I (n=5) rigid IOL polymethylmethacrylate (PMMA) was used and in group II (n=17) square edge foldable acrylic lens was used. Cataractic lenses were removed by phacoemulsification using coaxial operating microscope. The animals were reviewed for surgical outcome, intraoperative and postoperative complications. Success rate was determined by dividing the number in which successful restoration of vision was observed with the total number of the eyes operated for cataract surgery and lens implantation. The results showed that restoration of functional vision was noted in 1/5 (20%) and 11/17 (64.70%) in group I and Group II respectively at the end of the study. Intraoperative complications observed were hyphema andmiosis in both groups however these complications were significantly lower in group II. Postoperative complications included corneal opacity, uveitis and corneal oedema in both the groups but severity of the complications were lower in group II.To conclude intraocular foldable lens implantation with +41D following phacoemulsification was found comparatively  effective technique with success rate of 64.70% for management of mature cataract in dogs.
