THE OUTCOMES OF FEMTOSECOND LASER – ASSISTED ARCUATE KERATOTOMY COMBINED WITH CATARACT SURGERY
Main Article Content
Abstract
Purpose: To evaluate the outcomes of femtosecond laser-assisted arcuate keratotomy combined with cataract surgery in eyes with low to moderate corneal astigmatism. Method: This prospective cohort study records 30 patients with preexisting corneal astigmatism ranging from 0.5D to 2.5D. Study parameters include corneal astigmatism, uncorrected (UDVA) and corrected (CDVA) distance visual acuities preoperatively and at 1 week and 1 month postoperatively. Results: The corneal astigmatism is reduced significantly from 0.90 ± 0.40D preoperatively to 0.16 ± 0.20D at 1 month postoperatively (p < 0.001). 28 eyes (93.3%) have postoperative corneal astigmatism of 0.5D or less. The postoperative mean UDVA and CDVA were 0.09 ± 0.2 logMAR and 0.02 ± 0.04 logMAR, respectively. 28 eyes (90%) have a postoperative UDVA of 20/30 or better. No intraoperative or postoperative arcuate keratotomy-related complications are recorded.
