The word LASIK is an acronym for Laser- Assisted In-Situ Keratomileusis (LASIK) and is currently a popular surgical procedure that is being performed by Eye Doctors to improve vision by correcting refractory errors.

The surgery improves the vision in patients who have nearsightedness, farsightedness, and astigmatism. LASIK surgery usually takes less than one minute per eye. Treatment involves reshaping the cornea - the protruding portion of surface of the eye - to improve vision.

In 1990, Dr.Lucio Buratto of Italy and Dr.Loannis Pallikaris of Greece pioneered the LASIK technique. They blended two prior techniques, Keratomileusis and photo refractive keratectomy effectively, to discover the LASIK technique, which is popularly used in the corrective refractive surgery.

Dr Jose Barraquer in 1990 in Colombia developed a device that could cut thin flaps in the cornea and alter its shape. This device was the 'Microkeratome' and the procedure was called keratomileusis. The basis of LASIK surgical technique is reshaping the cornea to correct refrectory errors.
