Benefits of LASIK eye surgery to gain the accurate vision for eye

lasik

LASIK is an outpatient surgical procedure. It will take 10 to 15 minutes to perform for each eye. For clear vision, the eye's cornea and lens must bend light rays properly. This allows images to be focused on the retina. Otherwise, the images will be blurry. This blurriness is referred to as a refractive error. It is caused by an alteration between the shape of the cornea and the length of the eye. LASIK uses an excimer laser to eliminate a small amount of corneal tissue. This gives the cornea a new shape so that light rays are absorbed clearly on the retina. LASIK causes the cornea to be solvent. The only sedative used is eye drops that numb the surface of the eye. The procedure is done when you are conscious, but you will get drug to help you relax.

LASIK may be done on one or both eyes during the same session. To do the procedure, a flap of corneal tissue is created. This flap is then peeled back so that the excimer laser can reshape the corneal tissue underneath. A hinge on the flap prevents it from being completely separated from the cornea. When LASIK was first done, a special automated knife was used to cut the flap. Now a more common and safer method is to use a different type of laser to create the corneal flap. The amount of tissue the laser will remove is calculated ahead of time. Once the reshaping is done, the surgeon replaces and secures the flap. No stitches are needed.
