What is Lasik Surgery? Know about Lasik surgery Age Limit
LASIK surgery or Laser-assisted in situ keratomileusis is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
Refractive surgery changes the shape of the dome-shaped transparent tissue (cornea) in the front of your eye. The desired result of LASIK eye surgery is to bend (refract) the light rays to focus more precisely on your retina rather than at some point beyond or in front. The end result of successful LASIK eye surgery is clearer sharper vision.
During the procedure, the eye surgeon creates a flap in the cornea and then uses a laser to reshape the cornea and correct focusing problems in the eye. LASIK surgery is most appropriate for people who have a moderate degree of nearsightedness (myopia), in which you see nearby objects clearly, but distant objects are blurry; farsightedness (hyperopia), in which you can see distant objects clearly, but nearby objects are blurry or astigmatism which causes overall blurry vision.
A good surgical outcome depends on careful evaluation of your eyes before the surgery.
Spectacles contain lenses that alter the incoming rays of light to allow them to focus on the retina and contact lenses enhance vision performance, especially for higher refractive errors, because they are placed on the cornea. But after LASIK surgery, you wear no lenses at all.
The procedure is typically performed under topical (eye drop) anesthesia. During the surgery, you will be asked to lie down on the operating table and focus on a light above.
The entire LASIK procedure takes only 20 minutes and the Laser delivery itself takes less than a minute. Lasik is usually done for both eyes together as it gives a better visual recovery. You can return home a few hours after the surgery and go back to work after one to three days.
It is common to experience varying degrees of discomfort beginning 30-90 minutes following the surgery as the effect of the numbing drops begins to wear off. It is advisable to go home, close both eyes and rest for the remainder of the day following the LASIK procedure.
