Abstract Details

Purpose:

To evaluate and compare visual outcomes of both eyes in patients that underwent a small-aperture corneal inlay insertion in the non-dominant eye immediately following a LASIK procedure in both eyes.

Setting:

Optilase Eye Clinic, Ireland, Europe

Methods:

41 patients underwent bilateral LASIK with inlay insertion into a lamellar pocket 100 microns below the flap interface in the non-dominant eye. Traditional LASIK procedure was performed to achieve a post-op refractive target of -0.75D in the inlay eye and plano in the fellow eye. The LASIK and inlay implantation surgical procedures were performed consecutively on the same day. Uncorrected distance, uncorrected near and best-corrected distance visual acuity (UDVA, UNVA and BDVA respectively) outcomes were assessed at pre-op, 1, 3 and 6 months in both eyes. Mean ± standard deviation visual acuity is reported in decimal notation with Snellen equivalents.

Results:

In the implant eye, UNVA improved 5 lines from 0.20 ± 0.16 (6/30) preop to 0.63 ± 0.18 (6/9) at six months. The mean UNVA in the fellow eye remained unchanged from 0.20 ± 0.09 (6/30) preop to 0.24 ± 0.12 (6/25)at six months. Mean UDVA improved from 6/12 to 6/7.5 in the inlay eye and from 6/12 to 6/6 in the fellow eye at six months. Mean BDVA was 6/6 in the inlay eye and 6/5 in the fellow eye at all postop visits. UDVA, UNVA and BDVA were all significantly different between the inlay and the fellow eye.

Conclusions:

Results from this study demonstrate that small-aperture corneal inlay improves near visual acuity significantly with minimal change to distance visual acuity when compared to the fellow eye. Same-day dual-interface technique for corneal inlay implantation with laser vision correction is an effective surgical treatment option for ametropic presbyopia.
