Wavefront Epi-LASIK (also known as Modern PRK, Advanced Surface Ablation, Photo Refractive Keratectomy, and LASEK) is a popular “bladeless” laser vision correction procedure, which does not require making a flap or using ANY sharp instruments during the procedure. Rather than using a laser to create a LASIK flap, the surface epithelial skin cells are instead brushed away with a “soft brush” epithelial polisher before the wavefront excimer laser reshapes the cornea. In Epi-LASIK, the actual procedure is completely painless, but patients usually report moderate discomfort during the first 3-4 days, as the corneal epithelial skin cells heal over the laser-treatment area.
The final results are identical with LASIK and Epi-LASIK. Though LASIK has a faster healing time and less discomfort, in certain clinical scenarios Epi-LASIK may be the treatment of choice. While we strive for an ideal patient experience, we always prioritize long-term safety over achieving an instant recovery.
