Abstract

Purpose: To assess PC-IOL optic adherence in surface modified IOL and impact on Nd:YAG capsulotomy rate and visual quality

Methods: Prospective interventional study of 93 eyes implanted with surface modified hydrophobic acrylic IOL. Primary outcome was PC-optic adhesion on ASOCT and YAG capsulotomy rate. Secondary outcome was visual quality. Follow up performed on POD 1, 1 and 2 years

Results: Complete PC-optic adhesion was seen in 2.9% cases on POD1, 67.6% cases at 1 year and 73.5% at 2 years. Strehl ratio (p=0.01) and MTF (p=0.03) were significantly better with complete PC-optic adhesion. Residual PC-optic distance positively correlated with total HOA (Pearson coeff=0.4, p=0.02). At 2 years, PCO developed in 7.5%; of these, 85.7% had persistent PC-optic non-adhesion (p=0.001). YAG capsulotomy was needed in 3.2%; all these cases had persistent PC-optic non-adhesion

Conclusion: PC-optic adhesion is associated with significantly less Nd:YAG capsulotomy rate and superior visual quality
