Femtosecond laser–assisted arcuate keratotomy at the time of cataract surgery for the management of preexisting astigmatism

Abstract

Purpose: To evaluate the outcomes of femtosecond laser–assisted arcuate keratotomy combined with cataract surgery in eyes with low-to-moderate corneal astigmatism. Setting: Eyes of York Private Practice Ophthalmology Clinic, York, Pennsylvania, USA. Design: Retrospective case series. Methods: This retrospective analysis included case records of patients with preexisting corneal astigmatism ranging from 0.5 to 2.0 diopter (D). Study parameters included corneal astigmatism, refractive astigmatism, and uncorrected (UDVA) and corrected (CDVA) distance visual acuities. The results, which were analyzed at 3 months postoperatively, included frequency distribution histograms, vector analysis, and single-angle polar plots. Results: The study comprised case records of 189 eyes of 143 patients (56 men and 87 women). The postoperative refractive astigmatism was reduced significantly compared with preoperative corneal astigmatism to 0.14 D ± 0.23 (SD) from 0.92 ± 0.34 D (P
