Information

Normally, your eye "sees" with your cornea (front part of the eye) focusing light onto the retina (back part of the eye) to create an image. If the cornea is imperfectly shaped or if the eyeball is longer or shorter than normal, a distorted image is projected onto the retina resulting in blurred vision.  

Laser eye surgery is actually quite simple and involves reshaping the cornea to allow it to focus on the retina. Different sight problems require different treatments as detailed below:

 

Myopia - the central apex or peak of the cornea is flattened to reduce the degree of short-sightedness.

Myopia - the central apex or peak of the cornea is flattened to reduce the degree of short-sightedness

Hyperopia - the central apex of the cornea is made steeper by applying the excimer laser to the edges of the cornea, reducing the effects of long-sightedness.

Astigmatism - this occurs when the cornea is more curved in one direction than the other resembling the shape of a rugby ball rather than a soccer ball, so the laser is applied to make the cornea more evenly curved.

Since it was first performed in Australia in the early 1990’s, corrective laser eye surgery has become very popular, with many thousands each year choosing it to correct their long or short-sightedness or astigmatism.

  • More than 30 million people world-wide have had laser eye surgery
  • More than 96% of people who have had LASIK or PRK treatment no longer need glasses or contact lenses
