Short-term Clinical Outcomes of Implantable Collamer Lens Implantation with Simultaneous Full Thickness Astigmatic Keratotomy

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.
