What is and why it is proving popular with so many people?
Eye Laser Surgery
Traditionally, spectacles or contact lenses are used to correct eye sight problems. However, in recent years, lasers have become a very popular alternative.
How works.
A laser is directed on the cornea, the outer, clear round structure that covers the colored part of the eye (the iris) and the pupil (the black hole). For people with myopia (short-sightedness), for instance, the laser is set to reduce the thickness of the cornea. This enables the eye to bring images into focus properly.
The cost of laser eye treatment varies between clinics but generally starts at around £500 per eye.
Types of
There are three main types of laser eye treatment.
Eye Laser treatment - LASIK
At the time of writing (July 2007), the newest and most popular type of laser eye treatment is called LASIK. LASIK is usually used on patients with severe long sight or short sight. LASEK is used on patients with moderate or mild short sight.
Under this procedure, a thin layer of the eye's cornea is sliced off to create a flap. This enables the laser to target the tissue underneath. The flap is simply replaced and grows back naturally. Vision is restored almost immediately.
Eye Laser Treatment - EPIFLAP or LASEK
This Eye laser Treatment involves the partial removal of the epithelium or outer layer of cells on the eye to reveal the cornea. The cornea is then flattened or reshaped by a laser and the outer cells are pushed back and the eye heals within a few days.
Eye Laser Treatment - PRK
PRK was the standard laser eye treatment for many years but is not common today. It involved

the complete removal of the epithelium or the outer layer of cells on the eye.
Are these treatments safe?
All of these treatments have been approved for use in the UK and are therefore considered safe. However, it must be recognised that ALL surgical procedures involve an element of risk and eye surgery is no different. Doctors are expected to warn patients that the treatment does involve risk.
Medical opinion is somewhat divided over some of the newer treatments. This is largely because they have not been around very long and there are no long-running studies into the long-term effects of some of the treatments. In some cases, patients have suffered major complications and required cornea transplants following laser treatment.
For this reason, we recommend that you throughly research the available information on Eye Laser Surgerys on www.lasikresearchlibrary.com, which is one of the largest Lasik research resources in the world) and contains summaries of LASIK and laser eye treatment reviews and clinical studies from all over the world.

Can everyone have laser eye treatment?
No. laser eye treatment is only suitable for certain people. It is usually only performed on healthy adults.
People who have just mild eyesight problems are not generally considered good candidates. Similarly, those whose eyesight has changed significantly in the past 12 months may also be refused because their eyesight is still getting worse. Diabetes, pregnancy and arthritis and other similar conditions can also rule people out.
How popular is laser eye treatment?
Laser eye treatment is getting more popular every year not least because prices are coming down and the treatment is more widely available. It is estimated that more than one million Americans are now having their eyes lasered in the US each year.
