To evaluate the beveled, full thickness astigmatic keratotomy.

This study included 185 eyes of 112 patients treated with beveled, full thickness astigmatic keratotomy. Treated eyes were divided into 3 groups: beveled, full thickness astigmatic keratotomy after implantable collamer lens (ICL) implantation (group A), beveled, full thickness astigmatic keratotomy after cataract surgery (group B) and beveled, full thickness astigmatic keratotomy alone (group C). Follow-up visits were at 1 week, 1 month, 3 months and 6 months. The outcome measures included uncorrected distance visual acuity, astigmatism, efficacy, safety and predictability.

At 6 months postoperatively, astigmatism was significantly reduced: 68.9 ± 18.24% in total, 69.24 ± 20.76%, in the group A, 67.84 ± 17.56% in the group B and 67.82 ± 13.97% in the group C. The proportion of eyes with astigmatism 1.0 or less was 88.65% in total, 91.49% in the group A, 87.5% in the group B and 70.0% in the group C. Mean improvement in corrected distance visual acuity (CDVA) was 0.56 lines; no eyes lost 2 lines of CDVA after 6 months postoperatively. Postoperative complications were not observed.

This study showed the beveled, full thickness astigmatic keratotomy is effective and safe for correcting astigmatism alone as well as correcting astigmatism after ICL implantation or cataract surgery.
