LASIK, LASEK and LASAK revealed

Monday, March 8th, 2010

Basically there are three eye surgery methods. All of them are called almost the same: LASIK, LASEK and LASAK. Those methods can be combined with two other treatments to give a better result. Those two methods are: Wavefront treatment and Aspheric treatment.

Because it is fast, gentle and effective, LASIK is the most popular method. There are very few complications, so it will be a good eye surgery method for most people.

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.

For people who are only a little long-sightedness or near-sightedness (from -2 to +2), the LASEK surgery is a great method.

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.

LASAK is the most modern method of eye surgery. The flap, which is cut off, is thinner than when using the LASIK method. Because of the saved corneal tissue, it is a great method if you have thin corneas.

LASAK do also have a shorter healing time than the other operations. There is no pain after the surgery and the risk of complications is very low. The eyes will not be as dry as with the other operations, and the sight will be 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.

Without the Aspheric treatment the eye will be more ball-shaped when operating using LASIK, LASAK or LASEK. The result is reduced contrast ratio and bad night sight. When using the Aspheric treatment in combination with one of the three eye surgery methods, the curve in the central part of the eye will be made larger; which copy the normal (untreated) eye. With this method this method the result will be better; sometimes the sight will be even better than when using glasses or contact lenses.

Why You Do Not Have To Fear A Lasik Surgery

Thursday, January 7th, 2010

Thinking about eye surgery using a Lasik procedure is a big step, and many people are a little hesitant to ask the questions that they have. The Lasik procedure, though widely talked about, is not discussed in detail, and people tend to fear the unknown. This article addresses some of the more commonly held fears, and talks about the experience for the vast majority of people that undergo a Lasik procedure.

In both Lasik surgery and all other kinds of operations, a common fear is about the pain during and after the operation. But a Lasik surgery is almost painless. Before the Lasik surgery is performed the eye will be applied with numbing drops. You will also be provided with a mild sedative to relax you and make you comfortable. So even though there can be a small pressure to the eye, you will not feel any pain.

Many people do also fear the actual operation where the laser is used to reshape the cornea to improve the sight. It can seem dangerous that the laser is used directly on the eye. And what if you look away? Will it hurt your eyes? There is nothing to worry about. The operation is only performed for about ten to fifteen seconds for each eye. And a sophisticated tracking system will make sure that the laser stops, if the eye is not in position.

Another common fear is the fear of “the scalpel”. All the eye surgeries use either a very small microkeratome blade or the laser itself to create the flap that is needed to perform the laser operation. So there is no reason the fear about a scalpel, because it is actually not used.

You hear horror stories every day about operations that went wrong, so it is just natural to wonder about the risks; especially the risk about going blind. But there have never been reported any cases of blindness due to a Lasik operation according to government statistics taken by the FDA.

Actually, the risk of a serious permanent complication due to the Lasik procedure is less than 1 percent, and the risk of any permanent complications even if not serious (such as light halos) is 3 percent or less. It is extremely rare for a patient to not have improved vision after a Lasik procedure.

If the thought of being awake and having your eyes open during the Lasik procedure bothers you, remember that you will be given a mild sedative for the procedure, and that your eyes will have numbing drops administered to them.

Are you more bothered about the thought of the Lasik physician’s hand approaching your eyes? Right before the surgery your eyes will be dripped with drops that makes your vision black out for ten to fifteen seconds; long enough for the surgery for that eye.

The 3 Eye Surgery Methods

Saturday, October 10th, 2009
by Martin Elmer

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.

Because it is fast, gentle and effective, LASIK is the most popular method. There are very few complications, so it will be a good eye surgery method for most people.

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.

For people who are only a little long-sightedness or near-sightedness (from -2 to +2), the LASEK surgery is a great method.

If you have thin corneas the LASEK surgery is a great method, because the laser surgery is made on the surface of the corneas. It also more gentle, if you have very 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.

LASAK do also have a shorter healing time than the other operations. There is no pain after the surgery and the risk of complications is very low. The eyes will not be as dry as with the other operations, and the sight will be steadier.

The surgery result can be improved even more, if the methods are used in combination with the Wavefront method. The irregularities on the corneal are measured with a special instrument, and a kind of topographic map is constructed. Finally a computer calculates the correct settings for the laser surgery based on the specific eye.

By using the Wavefront method, the result will be better because of the unique measurement of the eye. The method does also give a better night sight and astigmatism in the eyes will be treated with a better result.

The newest improvement in eye surgery is called Aspheric treatment; which is used together with one of the three surgery methods. The cornea is aspheric and not ball-shaped; something the Aspheric treatment takes into account.

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.
