h Since about 1996 LASIK (Laser In-Situ Keratomileusis) has become the preferred surgical method of correcting vision because of its rapid recovery of vision and lack of pain. Prior to this, surface laser treatment (PRK) was the only method widely available.LASIK surgery first appeared in 1989 when a flap of corneal tissue was created and the excimer laser was applied to the deeper corneal tissue. The technique of creating a flap had been used in various eye operations for many years but this was the first time that it was combined with the use of the excimer laser and it proved to be a major turning point in laser vision correction. The majority of laser eye surgeries performed today are LASIK.The LASIK procedure involves firstly creating a thin, circular flap of tissue on the cornea with either IntraLase or a microkeratome. The flap is then folded back to expose the underlying corneal tissue and the laser remodels the exposed surface. The actual laser treatment only takes about 30 seconds. The flap is then re positioned and allowed to settle for a few minutes and no stitches are required.

Numbing drops are placed on the eye. img2Laser is used to create a very thin flap on the front surface of the cornea. The flap is lifted to allow the laser to reach the treatable area of the cornea. img3Another laser is applied to the cornea. The cornea is reshaped to correct your refractive error. This takes as little as 30 seconds.
img4The laser treatment is completed and the corneal shape has been altered, adjusting the way the incoming light focuses on the retina. img5The flap is returned to its natural position, adhering to the corneal surface and healing begins. img6The procedure is complete. The whole process has taken less than 15 minutes. The eye is comfortable but vision may be blurry for about 12 hours.
