Lasik has become the most advanced procedure in the world for the treatment of short-sightedness, long-sightedness and astigmatism. Apart from the millions of people who now enjoy everyday life unencumbered by glasses or contact lenses, there are also those whose livelihoods and fame depends upon them having the best possible vision.
LASIK (Laser Assisted In Situ Keratomileusis) combines the precision of the excimer laser and the microkeratome to gently lift a thin layer of corneal tissue. Each pulse of the laser removes 39 millionths of an inch from the Cornea and does not cut or burn tissue.
LASIK (Laser Assisted In Situ Keratomileusis) commonly referred to as laser eye surgery is a combination of two techniques. It combines the submicron precision of the excimer laser with lamellar corneal surgery (a procedure that has been performed since the 1960s).
During the laser eye surgery procedure, a very thin flap of corneal tissue is first raised. The Excimer laser then smooths and reshapes the underlying bed of cornea to correct the patient’s refractive error. Each pulse of the laser removes 39 millionths of an inch in 12 billionths of a second. The Excimer laser produces ‘cool’ ultra-violet light that does not cut or burn tissue.
The thin flap of corneal tissue is precisely replaced to cover the newly curved central cornea. It seals within minutes due to the corneas efficient bonding ability without the need for sutures. This flap minimises the risk of infection and accelerates the healing process following laser eye surgery. Patients can see immediately after the operation.
The LASIK method has been used to treat over 50 million eyes, providing exceptional accuracy with a fast healing time and minimal discomfort.
In short-sighted patients, the laser removes a little more tissue from the centre of the cornea than the periphery, which flattens the cornea (the amount taken is often less than the thickness of a human hair). In long-sighted patients, the laser takes more tissue from the peripheral part of the cornea in order to steepen the cornea.
In astigmatic patients the curvature of the cornea is not completely spherical – it is more elongated on several planes. The laser removes tissue from different axes to provide a more spherical cornea that can accurately focus light.
The Australian Institute of Eye Surgery is patient focused and aims to achieve the finest possible results by the safest and most predictable means.
Your surgery will take place in our nationally accredited Day Surgery. Once comfortable on the operating bed, your eyes will be opened by a spring for the duration of the procedure. The surgery itself takes about 10 minutes per eye. At the end of your procedure, some anti-inflammatory and anti-bacterial eye drops will be administered. You will then walk out of the surgery and be guided into our post-treatment area for a quick recovery.
