What is the difference between laser and LASIK eye surgery?

laser

In laser operations, the laser is shed on the cornea directly by using an excimer laser on the surface of the cornea to correct myopia, and the cells are healed
Superficial over a period of 5 - 3 days and a special contact lens is placed to relieve pain and to speed the growth of surface cells that heal completely without any effects at all, but what bothers the patient is the pain resulting from the surgery.

LASIK

In LASIK operations, a thin layer is lifted from the surface of the cornea by a sensitive and very accurate device, with a thickness of between 160-110 microns (noting that the normal thickness of the cornea ranges between 600-500 microns), then an excimer laser is used on the remaining surface of the cornea, after which the thin layer is returned from the surface of the cornea The cornea is in its place over the treated part. In these cases, there is no significant pain after the operation, and the place of the operation is healed quickly compared to the superficial laser. LASIK is used in cases of severe myopia and when the thickness of the cornea is sufficient for this type of operation.

As for the surface laser, it is used for simple and medium cases whose short-sightedness or farsightedness does not exceed six degrees, and in cases where the thickness of the cornea is
Not enough to perform LASIK operations.
