Many people who suffer from vision problems such as short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism are turning to corrective eye laser treatment to help correct their vision. However, some people may prefer to understand how the procedure is carried out and what is involved before they go ahead with it.

Firstly, you must choose a clinic. It may be advisable to keep your options open – many clinics offer free consultations. Remember, cheaper is not always the best option, you should view quality of the surgery and surgeons more important than getting the best deal possible. Get in touch with a few clinics, see what they can offer and choose what’s best for you.

Before the procedure can be carried out, you will need a full consultation and eye exam. Not everyone is eligible for LASIK eye surgery, for example it is not advisable for those with thin corneas to go for this option and your eyes must be stable for a certain period of time before the procedure, but if you are then an eye exam will be carried out. This will review the current health of your eye, and a corneal topographer is used to map the surface of the cornea which will allow the eye doctor to use LASIK eye surgery to make improvements more suited to your eyes.

Before going through with the procedure, you need to make sure you are fully prepared beforehand, your eye doctor should have fully informed you of these preparations. In the clinic of the day of the laser eye surgery, eye drops will be used, with antibiotic eye drops being used to clean the eye and anaesthetic  eye drops used to make sure the eye laser treatment is as painless and comfortable as possible.

After being asked to recline of a chair under the laser, a speculum in put in place. This is a device used to help prevent you from blinking while the procedure is being carried out. This may be a little uncomfortable, and at worst you should feel slight pressure on your eyes, but it shouldn’t be painful.

A small circular flap is then cut into the cornea of the eye being treated. This is lifted by the eye doctor. Then, you will be instructed to look at a small light during the procedure. IT is important to keep your eye as steady as possible, but a tracking system is in place, which tracks the movement of your eye to make sure the procedure and corrections go as smoothly as can be.

The laser will now send tiny beams to shape the cornea as needed, which will be in line with the measurements taken from the corneal topographer, and the eye doctor will monitor the progress of the laser. After the shaping is complete, the flap in your cornea will be smooth back into place and allowed to begin healing. You may be given eye drops immediately after eye laser treatment for comfort following surgery.

The surgery itself usually takes no longer than 10 minutes per eye, and is often much quicker than that, with some people able to leave the surgery room within 20 minutes of entering. Aftercare will have been explained, and eye drops will be provided to help alleviate any discomfort and also to help healing. You may also be provided with an eye shield of some kind, usually in the form of safety glasses. This is to prevent you from rubbing your eyes, especially at night when you may do so unconsciously or upon waking.

Upon getting home, the best and most advised thing to do is to go and take a nap. After a short nap, many people wake up to find that their vision is already drastically improved, and improves even further after a few days following treatment. You will have a number of follow up appointments to make sure your eyes are healing as they should and to assess how successful the procedure was. Many people walk away from this to find they have 20/20 vision, and some people walk away with even better vision than that!

In the days, or sometimes weeks, following eye laser treatment, you may have an issue of a ‘gritty’ feeling, and your eyes may be dry. This is usually a short term issue, and as your eye heals it should reduce. In some cases, dry eyes can last a little longer, sometimes having to suffer for months, but eye drops can be used to help alleviate the discomfort. Some people may also suffer slight light sensitivity, and possibly glare or halos around lights at night. But, again, this will usually diminish as your eye heals.
