What is LASIK eye surgery

If you are suffering from some kind of eye disorder, most probably you know the feeling of not being able to distinguish people, their facial expression, image on the television, sceneries and sad to say your surroundings.
I am having perfect eyesight so I am not speaking from experience but the closest people around me are suffering from some kind of eye disorders from mild to severe. I feel their pain and anguish when they struggle to look for their glasses or when they lose their contact lenses.
However, recently for them all that changed after they had a surgery.

The only word I get from them after the surgery is – Freedom

Currently there are several types of surgical techniques being performed daily to correct refractive errors. Refractive eye surgery is a procedure intended to correct the common eye disorders or refractive errors such as Hyperopia (farsightedness), Myopia (nearsightedness) and Astigmatism (distorted vision).

Of all the corrective methods the laser based laser refractive correction is the most technologically advanced method available which allows for unparalleled degree of precision and predictability.

The Food and Drug Administration first approved the excimer laser in October 1995 for correcting mild to moderate nearsightedness. With that approval, the agency also restricted use of the laser to practitioners trained both in laser refractive surgery and in the calibration and operation of the laser. Currently, the excimer laser has been approved for use in a procedure called photorefractive keratectomy (PRK), and, as of November 1998, for a procedure called laser in situ Keratomileusis (LASIK).

The LASIK procedure is the latest technology, which for most patients, is the superior technology for vision correction
