LASIK surgery has become common enough that most people have not only heard of it; most people know someone who has had a LASIK surgery procedure performed.
But, in spite of its growing accpetance, there are not a lot of people outside the medical profession who understand what LASIK surgery is LASIK surgery has often been
promoted as an instant fix for refractive error (poor vision correctable with glasses, contacts or refractive surgery). While it is a very fast procedure, usually
taking less than a minute for each eye,LASIK surgery can sometimes require half an hour to properly correct the defects in an eye. As with allmedical procedures, the
length of LASIK surgery will depend on the visual problem being treated and the variety of LASIK surgery being done.
LASIK Surgery Is Still Surgery
perhaps because of the short duration of most LASIK surgery,some people tend to regard LASIK surgery as a minor medical procedure , like having sutures removed. But
that is a very misguided perception; LASIK surgery is surgery, and it isbeing done on your eyes. You probably value your eyes tremendously, it is good be educated as
much as possible to have a full understanding of the prcedure.
What does LASIK surgery really do?
The cornea of your eye, although it is only half a millimeter thick, has five distinct layers. They are, form the outside in ,the epithelium; Bowman membrane; the
stroma; Descernet's membrane; and the endothelium. LASIK surgery will clean the cornea, which is responsible for light refraction. Poor light refraction results in
During LASIK surgery , aflap created which is a portion of the outermost later of cornea, the epithelium. The laser provides the treatment from calculations made in
office by testing along with doctors measurements custimized for the patient. The cornea narurally heals itself with time. Vision should be clear by the next morning
and patient should be able to drive the next day. Another type of refractive surgery is PRK. No flap is created and the treatment is provieded on the outside of the cornea. Healing time is a bit longer for comfort and clearity but the end results should be near the same. Your doctor will help you select the proper pocedure for you and your needs.
Everyone who has near or farsightedness knows what it means. But not many people can accurately describe asigmatism. Astigmatisms also affect the corneal light refraction, but they cause visual symptoms like starburstes, haloes, decreased night vision, and ghost images.
During LASIC surgery the doctor will focus on the area of the cornea which needs ablating, and treat extra tissue with a laser, broad beam lasers are preferred for the procedure because they can apply a strong light beam over an area of between six and eights millimeters, and can be used very close to corneal tissue.
It's A Medical Procedure, Not A Miracle
The entire point of LASIK surgery is to correct the cornea to as close to a normal shape as possible, improving its light refraction and therefore, your vision. Although LASIK surgery is certainly capable of producing what seem to be instant cures, bordering on the miraculous, possible side effects include dry eye during healing, and over or undercorrection.
