Objective: The advantage of iris-claw lens is that it can be fixated to the iris without applying sutures because the peripheral iris is incarcerated between the claws, so implantation of this lens takes a few minutes only, thus the hypotonic open sky phase is shortened compared to combined surgery. Our aim of this study was to evaluate the safety and efficacy of retropupillary iris-claw intra ocular lens implantation in our institution.
Methods: In this study 36 eyes with aphakia without capsular support were included prospectively. All the patients were evaluated properly and subsequently retropupillary iris-claw intra ocular lens implantation was done.
Results: The mean age of patients was 63.6 years with SD of 10.5 years. Highest number of patients were in the age group of 60-70 years (46%). The mean follow-up of patients was 3.1 years ranging from one month to six years. Out of 36 eyes, 25 (69%) eyes had visual acuity of 6/9, five (14%) eyes had 6/12, three eyes (8%) had 6/6 vision, two eyes had 6/24 and one presented with only perception of light and projection of rays. The most common postoperative complication was subconjunctival hemorrhage, seen in 13 (36%) cases. Two eyes developed secondary glaucoma in postoperative period due to pupillary block. Retinal detachment was observed in one eye. We have not seen any case of bullous keratopathy, infection or cystoid macular edema till last follow-up.
Conclusion: From our study as well as from other studies we have noted that, retropupillary iris-claw implantation in such patients is safe and effective among all the treatment modalities available at present.
