Lasik eye surgery - what is involved

Published on 8th May 2010

Most people will find that getting LASIK eye surgery is the best option for them when they need vision correction. Before this was available, only eyeglasses or contact lenses could be used but these have their inherent problems and can prove to be very inconvenient.

If you are considering getting LASIK eye surgery, it helps to understand a little bit about the process and what you can expect . You'll start with a consultation with a surgeon who can determine whether or not you are a good candidate for a laser eye treatment. Don't hesitate to speak to somebody as there are now procedures available for people with nearsightedness, farsightedness and even astigmatism.

Provided you are a suitable candidate, then an appointment will be set for the procedure. You can either choose to have both eyes done at once or separate the procedures by a week or two. Most people will prefer to have everything done at once when they find out how easy the procedure is.

First, eye drops are applied that will numb the eye. Subsequently, a flap is pulled back from the outer surface of the eye that allows the laser to reach the cornea. With a series of short pulses, the laser will reshape the cornea so that your vision is clear without further need of corrective eyewear. The flap is then replaced and the procedure is complete!

Following laser eye surgery, most people find that they experience clear vision after only a few hours. Some people even find that they observe a noticeable difference as soon as they open their eyes. Side effects are quite rare and usually very mild when they do occur. There are some cases where people have to go back to have an enhancement or further procedure. The lasers can track the small movements of the eye and adjust the pulses accordingly so most times one visit is all that it takes.

Following the procedure, it is wise to rest for a few days to make sure that the eyes heal properly. You will have a follow-up visit to ensure that everything is satisfactory and then there is nothing else you have to do.


All eye surgical procedures carry a level of risk including not obtaining the desired outcome, through to varying levels of visual loss. Your eye surgeon will discuss the risks and benefits, including ones specific to your circumstances, at the time of your pre-operative consultation.
