Laser eye surgery works by reshaping the cornea in the eye, when the cornea is misshapen this is when people need corrective lenses to see properly. This may result in short sightedness where objects far away are blurred or long sightedness where objects close up are blurred. The most popular form of laser is called LASIK developed around 1991.
The procedure itself is usually done under a local anaesthetic, the surgeon cuts a flap on the surface of the eye, lifts this and uses the laser to reshape the cornea. The flap is then replaced and there is no need for any stitches.
There are so many benefits from having this surgery. Those who wear glasses often imagine how nice it would be to wake in the morning and be able to see as soon as they open their eyes, without having to find glasses or put in their contact lenses. There won’t be any ongoing costs for sight examinations, frames and lenses.
Active people who like sports will benefit as they won’t need to wear sports goggles to protect themselves and swimmers often find laser to be the best option for them. People who wear contact lenses will find their appearance can be kept and there is no risk of infection or dry eye.
People need to remember however that not everyone is a suitable candidate for laser surgery. People usually need to be 21 or over with a stable prescription for the past 1 to 2 years. They must not have had any previous damage to the eye. People with severe correction required may also not be suitable.
This procedure, like most, is not risk free. There is a chance of infection, bleeding, over or under correction and sometimes even the need to have the laser eye surgery repeated later. As people get older they usually form presbyopia which cannot be treated with corrective laser.
