In Thailand, the first case of LASIK was performed in 1994 by the pioneering surgeons who later founded TRSC International LASIK Center. Since then TRSC has continued to contribute to improving the procedure to its state of the art level today.

           LASIK dates back to the year 1949, when the late Professor Jose I. Barraquer of Bogota, Colombia, came up with a method to change the curvature of the cornea to correct nearsightedness and farsightedness. The procedure, known as keratomileusis, involves using an instrument (the "microkeratome") to separate a layer of corneal tissue and carve it with a lathe. The corneal tissue is then sutured back to the eye. Keratomileusis proved to be a reasonably safe and effective procedure in trained hands. However, the complexity of the technique and its machinery prevented it from being widely adopted at the time.

            In 1983, Dr. Trokel was the first to recognize the potential of the excimer laser as a surgical instrument. It was first used in a procedure called Photorefractive Keratectomy (PRK), which utilizes the excimer laser to directly sculpt the cornea's outermost layers. PRK proved to be moderately safe and effective in the treatment of low refractive errors, but was less predictable in higher ranges.

            The utilization of the excimer laser in combination with the microkeratome was proposed by Drs. Buratto and Pallikaris at about the same time in 1990. The resulting procedure, called Laser In-situ Keratomileusis, or LASIK, combines the accuracy of the excimer laser with the paucity of tissue reaction of keratomileusis, resulting in one of the most accurate vision correction procedures in history. It is also one of the least disruptive, enabling most patients to return to work the very next day.
