Advanced Surface Ablation (ASA)
For patients with conditions such as thin corneas and loose skin of the cornea that make LASIK less than ideal, advanced surface ablation (ASA) is an excellent alternative for treating nearsightedness, farsightedness and astigmatism. In an ASA procedure, the vision correction is performed on the surface of the eye instead of under a flap in the cornea. This makes it a more extensive procedure than LASIK with a longer recovery time, but the results are very similar.
Usually, patients see well within several days after ASA treatment and only use medicated drops for the first several weeks after the procedure.
