What is LASIK?

Lasik involves raising a very thin corneal flap with the help of a special automated and very precise blade. After this the excimer laser treated is applied to the rest of corneal surface to change its shape and thus correct the refractive error. The parameters used for conventional Lasik are based on the refractive error of the patient. The raised flap is then positioned back, where it sticks without the need of any suture.
