ASLA Correction

Prior to the development of LASIK, Advanced Surface Laser Ablation, or ASLA, was the first excimer laser procedure.

ASLA involves applying the laser beam directly onto the surface of the cornea once the outer layer, the epithelium, has been removed, rather than under a corneal flap as in LASIK.

It may be associated with some discomfort and longer visual recovery than LASIK but it causes less thinning of the cornea and is occasionally preferable to LASIK in lower degrees of refractive error.
