Observational Study on Visual Outcome on Use of Iris Claw in Hypermature Cataract

Dr. Deep Panchal, Dr. Sujata Chahande

Abstract: Retropupillary iris-claw intraocular lenses (ICIOLs) have been increasingly used recently as a primary or secondary procedure of IOL implantation in eyes with insufficient capsular or zonular support. Aim To study visual outcome, endothelial cell loss and complications after retropupillary Iris claw lens implantation in patients with hypermature cataract having deficient posterior capsule due to weak zonules. Methods: This cross-sectional study included 30 patients who underwent retropupillary iris claw lens implantation in patients with hypermature cataract having deficient posterior capsule. Demographic details and data regarding pre operative status and postoperative events were noted, and compared. Results: The mean Preop Vision was HMCF and it improved to LogMar 0.13? 0.12, postoperatively which is equivalent to 6/18. Refixation/retucking of iris claw lens was observed in 4 (13.3%) cases, hypotonia and corneal decompensation was seen in 2 (6.67%) cases each. Conclusion: Retropupillary Iris Claw lens implantation is less time consuming, cost effective, predictable and safe procedure with good visual outcomes and fewer complications.
