Femtosecond laser thin-flap LASIK yielded similar visual and anatomic outcomes in eyes with thin corneas and normal topography, according to a study.

The retrospective study included 291 eyes of 146 patients with a central corneal thickness of less than 500 µm and normal topography. A control group included 371 eyes of 193 patients with a central corneal thickness of 500 µm or greater.

Outcomes were evaluated 3 to 6 years after surgery in the thin cornea group and 3 to 4 years after surgery in the comparator group.

At final follow-up, mean uncorrected distance visual acuity was –0.10 in the thin cornea group and –0.12 in the control group. Corrected distance visual acuity was –0.18 in the thin cornea group and –0.19 in the control group. Manifest refraction spherical equivalent was –0.13 in the thin cornea group and –0.10 in the control group.

At final follow-up, uncorrected distance visual acuity was 0.00 or better in 180 eyes in the thin cornea group (86.5%) and 319 eyes in the control group (86%). Corrected distance visual acuity was 0.00 or better in 207 eyes in the thin cornea group (99.5%) and 371 eyes in the control group (100%).

No eyes in either group had signs of corneal ectasia at final follow-up.
