The 3 Eye Surgery Methods

There are three different to use when doing eye surgery; all of them with almost the same name: LASIK, LASEK and LASAK. The three surgery methods can be combined with two extra methods to give an even better result. The names of the two treatments are: Wavefront and Aspheric.

LASIK is the most popular of the methods. It is fast, effective and gentle. And complications using this laser surgery method are very rare. For most people, LASIK surgery will be a good method to improve their sight.

LASIK surgery is almost painless, and the sight has improved only a few hours after the operation. The side effects are few; dry is the most common. LASIK can help most people; long-sightedness until +3 and near-sightedness until -12.

The other surgery method called LASEK (or E-LASIK or ELSA) is great for people, who are only a little near-sightedness or and long-sightedness (from -2 to +2).

Because the operation is made on the surface of the corneas, the LASEK surgery is especially good, if you have thin corneas. It is also better, if you suffer of dry eyes.

The newest type of laser surgery is called LASAK. The flap, which is cut off, is thinner than when doing LASIK surgery. That saves the corneal tissue and is therefore a better method for people with thin corneas.

Other advantages of the LASAK surgery are a shorter time of healing and lesser risk of complications. There is also no pain after the operation, and the eyes will not be so dry. Finally the sight is steadier.

To improve the result even further, the Wavefront treatment can be used in combination with all of the three laser surgery methods. A special instrument is used to measure the irregularities on the corneal, and a kind of topographic map is created. A computer makes a range of calculations, so the laser surgery is carried out for the specific eye.

With Wavefront the treatment will be unique, which gives a better result. The night sight will also be better. Finally astigmatism in the eyes will be corrected better.

Aspheric treatment is the newest step in eye surgery; and is used in combination with LASIK, LASEK and LASAK. The treatment takes into account that the cornea is not ball-shaped; but aspheric.

When using LASIK, LASEK or LASAK without Aspheric treatment, the eye will be more ball-shaped. That gives a reduced contrast ratio and a bad night sight. If the Aspheric treatment is used, the curve in the central part of the eye will be made larger (as it is in an untreated eye). This gives a much better result; sometimes even better than with contact lenses or glasses.

Benifits of Eye Surgery

Vision impairment is indeed a very big issue for some people as it effect their whole life when it comes to how they can live it. And it is not only the fact that they cant use their vision and eyes properly, it’s the fact that many people se the use of glasses and contacts as an hassle they rather escape. Fortunately there is help.

Laser assisted eye surgery has in the last years made a hugh leap in development and prices meaning that is now a very safe procedure and the price is nowhere near what it used to be. Today you can get the most common laser assisted surgery types for about 1200-1500 USD depending on where you live and your level of defect of vision.

Main reason for people having bad vision is that the light rays from our surroundings that hit our eyes (the cornea) may be poorly reflected into the eye thus producing a defect image on the retina and image nerve. This type of defect are common if you are near-sighted, far-sighted and/or have astigmatism.

Sow how does laser eye surgery work?

As a first step the doctor will analyze and measure your vision defect as a measure to know which how how the surgery will go forth. Next, he will, depending on your defect and other external and internal conditions choose which kind of surgery method he will choose. Today, the most common vision corrective surgery methods are LASIK and LASEK.

What these to technologies have in common is that they, with different methods first remove the outer part of the cornea. Either by using a tool to cut a small “flap” that can be folded away and then put back, or by using a fluid that softens and loosens the cornea, thus being able to remove it. Then with the middle part of the cornea exposed a, a laser is used to vaporize just enough material in the eye so that any defects become corrected and you get your vision back.

Depending on which method used the patient and the eye is then fitted with a soft contact lens that works like a bandage and/or protective film.  Normally healing is fast and usually take about 3 to 4 days.

Laser eye surgery can work miracles for anyone that feel that their eyes are worth more than just glasses and contacts. Adding to the fact that the prices today is probably considerable less then what you spend on glasses and contacts over a lifetime and you will be able to live a more active lifestyle there is no reason not to consider it.
