摘要

To determine postoperative refractive and visual outcomes and astigmatic changes after femtosecond laser astigmatic keratotomy in femtosecond laser-assisted cataract surgery (FLACS). This was a prospective interventional case series. Patients with age-related cataract and corneal astigmatism (1.0-3.0D) were treated with FLACS and femtosecond laser astigmatic keratotomy (FSAK). All patients underwent examinations before and 3?months after surgery; visual acuity, subjective and objective refraction, and corneal astigmatism were evaluated and recorded for all patients by using an OPD-Scan III topographer. Vector analysis of astigmatic changes was performed by using the Alpins vector method. Twenty-five patients were included in the study. Postoperatively, refractive and corneal astigmatism were both reduced significantly (P??0.05), concurrent with improved uncorrected distance visual acuity and corrected distance visual acuity. The rate of spectacle use was significantly reduced at 3?months postoperatively (P?=?0.001). The mean magnitude of the target-induced astigmatism vector (1.40?±?0.37D) was slightly higher than the mean magnitude of the surgically induced astigmatism vector (1.22?±?0.46D). The magnitude of error (-?0.18?±?0.36D), as well as the correction index (0.88?±?0.29), demonstrated slight undercorrection. The angle of error was 0.85?±?13.69°, which was close to zero. Combined femtosecond laser-assisted cataract surgery and astigmatic keratotomy may be an effective approach to manage preoperative astigmatism in cataract surgery, although slight undercorrection may exist during short-term follow-up.
