LASIK involves lasering under the surface of the cornea. A very thin superficial layer of the cornea is cut and lifted. After the exposed tissue is lasered, the flap is repositioned and remains in place by natural suction. The flap remains joined to the cornea like a hinge, enabling it to be replaced in exactly the same position, minimizing the healing process.

During LASIK eye surgery, a suction ring is applied to the eye to enable the flap to be made by a device called the Microkeratome. The laser is applied in the same manner as for Epi-LASEK laser eye surgery and the eye is covered with a plastic shield to prevent you from rubbing it. The treatment takes approximately 20 minutes (a special tracker locks onto the iris and the laser follows the eye if you move) and patients find the whole process quick and simple.

Epi-LASEK involves lasering the surface of the cornea under the epithelium. It is a combination of surface PRK and Epiflap. The laser is programmed for your individual prescription. The surface of the eye is lasered (cornea) without the need of surgery to the eye.

During Epi-LASEK laser eye surgery, the thin, protective outer layer of cells (epithelium) is softened with alcohol and folded aside. You then stare at the target light whilst the laser is applied to the cornea for about 30 seconds. Additional laser treatment for astigmatic correction, if required, takes place after a short pause and takes a further 15 seconds (dependent on the level of correction required). The epithelium is then gently pushed back into place. The treatment takes approximately 15 minutes.
