Dr. Chynn is, to the best of our knowledge, the only high-volume refractive surgeon in the US who performs 100% non-cutting Advanced Surface Ablations (ASA, defined here as LASEK or epi-LASEK), and who used to perform LASIK and had it himself, but switched to eliminate ALL flap-related complications (since there is no flap cut in ASA). All refractive surgeons will admit that the majority (defined as > 50%) of all LASIK complications are in some way flap-related (e.g., incomplete flap, full flap, buttonhole flap, flap striae, wrinkles, debris under the flap, DLK, post-LASIK ectasia or KC, etc.), so by eliminating the flap step, you eliminate the majority of possible complications!:)
