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.

Laser Eye Treatments Explained

Laser eye surgery can change the lives of those who choose it as a method for vision correction. The treatment can be used on people with varying levels of vision problems, even if they are very slight or very extreme.

However, there are several different types of treatment out there and this can get confusing because we can get overwhelmed with what’s on offer. What’s more, the thought of laser eye surgery is fairly frightening to some, so a blur of information is not very helpful when it comes to feeling better about the procedure.

One of the most common types of laser eye treatment is LASIK, which stands for Laser-Assisted-In-Situ-Keratomileusis. This procedure is performed many times every year with a high level of success and only takes around ten minutes to carry out, treating both eyes at the same time. During LASIK treatments, the eye is anaesthetised before a protective flap is lifted from the surface, revealing the inner corneal tissue. This tissue is then worked on by the laser, which reshapes the surface until it is corrected. The protective flap is replaced and left to heal.

Most patients report an improvement in vision within hours of this treatment, and many say that the levels of discomfort following the surgery are minimal. The eyes heal quickly and patients usually return to work within a couple of days.

LASEK stands for Laser-Assisted-Epithelial-Keratomileusis and is used to correct long and short-sightedness, as well as astigmatism. LASEK surgery involves the removal of the top layer of the cornea following the anaesthetising of the eyes. This layer is then sculpted by the laser to correct long and short-sightedness or astigmatism before being replaced and left to heal. Following LASEK, surgeons will place a soft contact lens on the eye to protect it and promote comfort.

LASIK is carried out more frequently than LASEK as it tends to have a faster recovery time. However, some patients are better suited to LASEK because they may be involved in contact sports or have thin corneas, for which LASEK is a better treatment.

IntraLase provides an alternative way to create the protective flap before LASIK surgery. It involves a laser being utilised in the creation of the flap and promotes even faster healing time.

If you are thinking about getting laser eye treatment, you will always have to undergo an in-depth consultation first – so you’ll never have to worry about getting the wrong treatment. However, it’s useful to know a little beforehand so you are prepared for the consultation and what will come up.
