    About Lasik

Lasik stands for laser in-situ keratomileusis and is the most common form of refractive laser eye surgery – that is surgery performed to correct refractive errors to reduce dependence on glasses and contact lenses.

Lasik is a two-step process using the Intralase method. The first step is the creation of the corneal flap using a specialised laser called the Intralase, and the second step is the vision correction using a second laser called an Excimer laser to smoothly reshape the surface beneath the flap. Once the laser treatment is complete the delicate corneal flap is precisely replaced and seals in place with no stitches required. The flap becomes adherent within a few minutes as the healing begins. Most individuals can return to normal activities within 24 hours. LASIK can be used to correct myopia, hyperopia, and astigmatism.

Total time: 15-30 seconds

The ultra-fast Intralase uses an infrared light beam, generating up to 60,000 pulses per second, to prepare an optimal corneal architecture below the surface of the cornea.

Using an “inside-out” process, the Intralase is precisely focused to a point below the surface of the cornea, where thousands of microscopic bubbles are formed to create the corneal flap.

The surgeon controls flap diameter, depth, hinge location and width, and side-cut architecture – factors that can be varied per patient. Bubbles are then stacked along the edge up to the corneal surface to complete step one.

The physician then exposes the prepared corneal bed for Excimer laser treatment by lifting the flap. The LASIK procedure is complete when the flap is securely repositioned on its bevelled edge.
