Abstract Details

Purpose:

To assess the effect of glare on contrast sensitivity in subjects implanted with multifocal IOLs.

Setting:

Isha Netralaya, Kalyan, India

Methods:

Its a prospective study where subjects implanted with multifocal IOL (Acrysof IQ PanOptix, Alcon; Triphobic, Care Group), aged between 40-70 years and best corrected visual acuity better than 0.1 logMAR were enrolled. Subjects with intra operative complications, ocular disease were excluded. Effect of glare on contrast sensitivity was measured at post operation 1 month ± 7 days using CSV- 1000 HGT (Vector Vision). Contrast sensitivity at 4 spatial frequencies (3,6,12 and 18 cycles per degree (CPD)) measured with and without automatically calibrated glare sources and were analyzed.

Results:

Forty five and 66 eyes with were implanted with PanOptix, and Triphobic IOLs respectively. The mean±SD age was 58.45±8.78 and 59.74±6.42 years in PanOptix, and Triphobic group respectively. In eyes implanted PanOptix IOLs the contrast was significantly reduced at 3 and 6 CPD (Paired t Test, p<0.05) however no effect was observed at 12 (p=0.68) and 18 (0.08) CPD. In eyes implanted Triphobic IOLs the contrast with glare was statistically significantly reduced at all spatial frequencies (Paired t Test, p<0.05).

Conclusions:

Overall contrast sensitivity was found to be reduced in the presence of glare in both the IOLs however it was not clinically significant.
