A microkeratome is a tool utilized to alter the form of the cornea, a main element of the eye, by cutting slim flaps of it. This process was called keratomileusis. Keratomileusis was a treatment to deal with the refraction of the cornea. This was accomplished by removing a deep corneal lamella, cold it, changing its curvature into a brand-new one, and after that changing it.

LASIK is the acronym for a procedure of the cornea - Laser-assisted In Situ Keratomileusis. This treatment was jointly developed by the two physicians named above by the blend of two techniques - keratomileusis, which I have actually explained earlier, and also keratectomy. LASIK eye surgery is extremely widely made use of nowadays due to two vital reasons:

oImproved precision contrasted to other earlier rehabilitative treatments involving the eye or cornea.

The evaluation is done making use of a computer-controlled scanner that shots low-power lasers to produce a map of the individual's cornea. The specialist prepares the coordinates for the surgery - the quantity of corneal tissue to be removed, the place of the tissue, and so on the patient is additionally recommended to make use of a moderate antibiotic to reduce the possibilities of the cornea getting contaminated post-LASIK surgery.

The patient is normally awake throughout the procedure; he might however be offered a sedative. The initial laceration is made using a microkeratome or a femtosecond laser as well as a flap of the cornea at the marked place is reduced.

All through the process, the placement of the eye is tracked by a computer, at rates of 4,000 times per second.

The degree of precision is often times sharper than that given by lenses or even traditional LASIK.
