LASIK is an acronym for Laser-Assisted in Situ Keratomileusis. It is s type of refractive eye surgery used to correct vision and eliminate the need for eyeglasses and contact lenses.
When the eye is seeing correctly, the multiple light rays are refracted (bent) by the cornea and lens, this joining at the retina in the back of the eye creates an image, which is then translated into neurosignals that the brain recognizes as vision. If the light rays are being refracted at the wrong angle, the image is distorted and vision problems result, such as myopia (near-sightedness) or hypermetropia (far-sightedness).
The goal of refractive surgery is to change the angle of refraction of the light rays passing though the cornea, this aids in the correct converge at the retina and restores proper vision. During a LASIK operation, the shape of the cornea is altered by carefully vaporizing the tissue with a laser. To correct myopia, the center of the cornea can be made more flat by removing more tissue from the center than from the edge. To correct hyperopia, the center of the cornea can be made more curved by removing more tissue from the edge than from the center.
Before the procedure, a local anesthetic is administered, usually in the form of eye drops, to numb the eye. Special tools are used to hold the eye in place and prevent blinking; a special cutting tool called a microkeratome is used to cut a very thin flap in the cornea. The flap is opened and the reshaping takes place.
The LASIK procedure itself is not uncomfortable or painful. The patient is awake during the procedure, and the process is completed in just a few minutes.
You will need to where a protective pad for about 24 hours. You may experience blurred vision for one to two days, after which time you can return to work or normal activity. Slight blurriness may persist but it should stabilize after one month.
