Manual versus femtosecond laser-assisted relaxing incisions for correction of low astigmatism in implantable collamer lens surgery.

ABSTRACT:

Purpose

To compare the safety, efficacy, and stability of astigmatism correction with manual versus femtosecond laser-assisted limbal relaxing incisions (LRIs) during implantable collamer lens (ICL) surgery.

Design

Observational case-series.

Methods

Charts of myopic patients with astigmatism <1.75D who underwent ICL implantation combined with manual or FL-assisted LRIs were retrospectively reviewed. Uncorrected and corrected distance visual acuities (UDVA, CDVA), refraction, and astigmatism parameters were evaluated at 1 month and 1 year postoperatively.

Results

From a total of 46 eyes of 32 patients, 19 eyes had FL-assisted LRIs (FLLRI group) and 27 had manual LRIs (MLRI group). The mean UDVA and CDVA improved after surgery in both groups. The FLLRI group show
