Abstract

PURPOSE
To evaluate the clinical outcomes of implantable collamer lens (ICL) implantation with simultaneous full thickness astigmatic keratotomy (FTAK) for the correction of moderate to high myopic astigmatism.
METHODS
Thirty-two eyes of 16 patients who had an ICL implantation with simultaneous FTAK were studied. Follow-up visits were at 1 week, 1 month, and 3 months. The outcome measures included the uncorrected distance visual acuity (UDVA), refractive error, efficacy, safety, and predictability.
RESULTS
After the surgery, astigmatism was reduced by 74.83 ± 13.8%. The proportion of eyes with a spherical equivalent of 0.5 D or less was 87.5%, and all eyes had a spherical equivalent of 1.0 D or less at 3 months after the surgery. The proportion of eyes with a UDVA of 20/25 or better was 100%, and 20/20 or better was 81.25%. Reoperation was needed in one case (3.1%) because of undercorrection of the astigmatism, and no complications were observed.
CONCLUSIONS
This study showed that ICL implantation with simultaneous FTAK is effective and safe for the correction of moderate to high myopic astigmatism.
