Abstract Details

Purpose:

To compare the visual outcomes and complications between eyes receiving retropupillary iris claw intraocular lens (IOL) and scleral fixated IOL (SFIOL) for post – cataract aphakia.

Setting:

M N Eye Hospital , Tertiary Eye Hospital ,Chennai , India Aravind Eye Hospital , Tertiary eye Hospital Pondichery , India

Methods:

Medical records of consecutive patients who had iris claw IOL and scleral-fixated IOL surgery from January 2010 and March 2015, with more than 1 year of follow-up were retrospectively analyzed. The surgical technique was based on individual surgeon preference. The best – corrected distance visual acuity (BCDVA), previous surgery, surgical technique, and complications were analyzed.

Results:

Iris Claw IOL was fixated in 48 eyes (46%) and SFIOL performed in the remaining 56 eyes. Iris claw was performed more frequently during primary cataract surgery (56%) compared to SFIOL (14%) (p<0.001). At 1 month postop, BCDVA was significantly better in the SFIOL group (0.3+0.2 logarithm of minimum angle of resolution (logMAR) vs. 0.7+0.5 logMAR, p<0.001) but this difference did not persist at 1 year (0.4+0.4 logMAR in Iris claw vs. 0.3+0.2 logMAR in SFIOL, p=0.56. Eyes with iris claw IOL experienced significantly more postoperative iritis (17%), intraocular pressure spikes (10%) and ovalization of the pupil (16%).

Conclusions:

Retropupillary iris claw IOL fixation is as safe as SFIOL for visual rehabilitation of post – cataract aphakia. Visual rehabilitation following iris claw IOL might take longer than SFIOL. Ovalization of the pupil is the commonest adverse effect reported with this type of IOL design.
