Many common eye defects and problems can be cured or improved by laser eye surgery. For this reason this kind of surgery is an extremely popular ‘cosmetic’ option nowadays and more and more people with eye problems are choosing this as an alternative to wearing glasses and/or contact lenses for all of their lives.

So, for example, the techniques used in this kind of surgery can help with a variety of eye defects. If you have, for example, astigmatism (problems with blurred or out of focus vision), myopia (short sightedness) or hyperopia (long sightedness) then this may be a solution for you.

Some of these common eye problems are basically caused by an issue with the way that your cornea is shaped. A regular cornea will be a round shape, kind of like a ball. But, the shape of a cornea with these problems will not necessarily be this regular round shape. If you have astigmatic vision, for example, then your cornea may well be more of an oval shape like an American football or a rugby ball.

This kind of shaping simply makes it difficult for the eye to process light as it should. With a regular cornea the light should pass into the eye to hit a certain point in a certain way. This is what helps you see objects as you should. If your cornea is not quite the right shape then you may well not be able to see so well because the light enters your eye and is processed differently.

Laser eye surgery simply works on your cornea and its surrounding tissues to make it more of a regular shape. If this works then your eye may well work better, doing away with the need for you to wear glasses or contact lenses from this point forward.

In some cases a laser surgeon will use a laser cutting tool or a scalpel to make a flap cut to access the cornea. In other procedures here, however, a cut is not actually made but the surface of the cornea is abraded instead to give the surgeon access. Then, he/she will use a specially designed laser to work on your cornea to ‘reshape’ it.

So, for example, if you have astigmatism the procedure here may work to flatten out your cornea to change the shape as it sits in your eye. This should give you more of a rounded cornea rather than an oval shaped one which may well sort out your vision problems.

Do bear in mind that not everyone should have this kind of surgery. It is important, therefore, to make sure that you find a surgeon who will look at your general medical history and the actual construction of your eye(s) to make sure that you are a suitable case for laser surgery.

So, don’t simply sign up for a laser surgery option where no tests or investigations take place. Your doctor should check your suitability first, make a recommendation on what kind of procedure you should have if you are a suitable candidate for surgery and then talk you through all the success factors and risks.
