Efficacy of image-guided accurate limbal relaxing incisions for astigmatism correction during cataract surgery.

ABSTRACT:

Purpose

To investigate the efficacy of image-guided accurate limbal relaxing incisions (LRIs) for astigmatism correction during cataract surgery.

Methods

Consecutive cataract patients with regular corneal astigmatism ranging from 0.75 to 2.50 D, intended for cataract surgery with image-guided LRIs, were recruited in this prospective cohort study. The efficacy of astigmatism correction was evaluated 3 months after surgery, and compared among eyes with preoperative corneal with-the-rule (WTR), against-the-rule (ATR) and oblique astigmatism. Higher-order aberrations and visual quality indices obtained with iTrace were further compared between eyes with single and paired LRIs.

Results

Totally, 108 eyes of 108 patients were analyzed. The mean total surgical induced astigma
