Abstract

Background: To compare the visual outcome and complications of posterior iris claw lens and scleral fixated posterior chamber lens. Methods: Prospective interventional hospital based study. A minimum of 60 patients fulfilling the inclusion criteria attending to R.L. Jalappa Hospital and Research centre, Tamaka, Kolar were selected for follow up study from December 2012 to June 2014. Results: 73.4% ICIOL & 63.3% SFIOL patients had final BCVA 6/18 – 6/6. 23.33% ICIOL patients and 33.33% patients were found in 6/60-6/24 group. Only 3.33% patients were in less than 6/60 group. Mean logMAR BCVA in both the groups were comparable. So in ICIOL group 80 % patients and 76.6% in SFIOL group had vision better than preoperative VA. Mean IOP in both the groups was same. Surgical time in ICIOL was significantly less than SFIOL group (P=0.00). Complications rate was high in SFIOL group than ICIOL group. Suture related complications and hyphema was common in SFIOL group but all these complications were treated. Pupil peaking was more in ICIOL group. One ICIOL was disenclavated on the 1st week visit which was re-enclavated again. Conclusion: Our results suggest that both the lenses have good visual results but in terms of complications posterior iris claw lens offers low incidence of complications, less invasive and time saving surgery. However , selection and meticulous surgical technique are critical and strongly influences the success of the procedure.

Key words: posterior iris claw lens , scleral fixated posterior chamber lens, aphakia.
