LASIK eye surgery is a surgical procedure that was pioneered by Loannis Pallikaris in 1991 in Greece.  And if you have been wondering what is LASIK eye surgery and why it is used know that it is a surgical procedure that is effective in correcting impaired vision due to refractive errors of the eye. LASIK eye surgery uses a special type of laser to reshape the cornea to that you are able to see better without the help of any kind of visual aids like glasses or contact lenses.

WHAT IS LASIK EYE SURGERY AND WHY IS IT NEEDED?

The answer to what is LASIK eye surgery is that it is a surgical procedure that is used to correct refractive errors of the eyes so as to improve vision. In humans the cornea and the lens in the eyes together are responsible for being able to see a clear image of an object. They together form what is known as the ‘focusing system’ of the eyes.  Under perfect situations the power of the lens of the eyes and the cornea is a perfect match with the length of the eyes, which is why you can see a clear image. It is when there is a mismatch in this system you will see a blurred image which is what is referred to as refractive error.

In terms of what is LASIK eye surgery and why it is required it is important to note that there are primarily three types of refractive errors that can be corrected by this procedure. Myopia, is such a visual condition which affects distant vision while hypermetropia, affects close vision. Another such visual condition is astigmatism in which multiple images are formed on the retina, because of distorted shape of either the lens of the eyes or the cornea and once you know what is LASIK eye surgery you will know how immensely beneficial a procedure it is when it comes to correcting these refractive errors.

If you have been researching on what is LASIK eye surgery you must know that this procedure can only be performed by a highly trained surgeon. It is a quick and effective procedure which takes only about a minute per eye.  The surgeon first creates a hinged corneal flap which has to be precise. The surgeon can use a surgical blade known as microkeratome or use an IntraLase laser with which the chances of complications are lesser and there is more precision. The surgeon then pulls the flap back to expose the corneal tissue and then uses excimer laser to reshape the cornea so that the light can be focused properly onto the retina. Then based on a pre-determined pattern that is unique to each person the cornea is reshaped. Then the flap is carefully repositioned and left to heal.
