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.

What You Need To Know About LASIK Surgery

Wednesday, November 4th, 2009

Because it is gentle, fast, efficient and with few complications, the LASIK surgery is the most popular eye surgery type today. It is a great laser surgery for most people; no matter if they suffer from farsightedness, nearsightedness and/or astigmatism.

The PRK laser surgery has been further developed to the new LASIK form. In both surgeries the outer cornea layer is removed, so the laser can operate on the tissue. But while the PRK method is scraping the out layer of, the LASIK operation cut just a flap in the cornea that can be bent. After the surgery the flap can be put back in place

The operation itself takes only a few minutes and is completely painless. The eye will be anaesthetized right before the surgery, and most people will not feel any pain at all. Subsequently the flap will be cut and the laser surgery can be made.

The actual laser treatment takes between 30 seconds and two minutes. A special laser called an Excimer laser will be used. It is specifically designed to operate in the eye’s sensitive tissues. Finally the corneal flap is put back again.

You can go home right after the operation. Because the eyes may sting a little bit, it is recommended to rest for the rest of the day; and maybe also take a nap.

Most people will already at that time feel that their sight has improved. Over the next weeks will stabilize.

The eyes can feel a little dry after the operation. Dripping them with salt water might help.

All studies indicate that a permanent sight improvement is provided by the LASIK operation. And previous bad eyesight will not return again. But a possible, natural change of sight in the future is not possible to prevent by the operation. So the surgery should not be done before the sight is stable.

The age-related long-sightedness that all people will experience can also not be prevented by a LASIK operation.

Should You Wear Contact Lenses Instead of Glasses?

Monday, June 29th, 2009
by Jaxon St. James

Are you tired and annoyed with wearing eyeglasses? Are you thinking about maybe switching to wearing contacts instead? Wearing contact lenses probably isn’t as difficult as you may think and there are a number of advantages as well. Find out more by taking a minute to read this short article about wearing contact lenses.

A Little History

Early contact lenses amazingly date back into the 19th century. At that time, they were made of brown glass and were not easy to wear. They were, however, helpful to people that could not wear eyeglasses. Contact lens technology improved in the 1940s and 1950 when they were able to make them from plastic instead. These were made out of a plastic material called polymethyl methacrylte and worked well. The only problem was that they did not allow oxygen to easily pass through them. Since then, the plastic material has improved and is now rigid gas permeable, allowing oxygen to get to your corneas. This is necessary because your corneas get the oxygen they need from the air, not your bloodstream.

Even in the last few years there have been an increase in technology in contact lenses as lenses are now being made for people with astigmatism and even for people who need bifocal lenses.

Why is it Good to Wear Contact Lenses?

People wear contact lenses for cosmetic advantages as well as:

* Unlike glasses, the lens moves with your eye so there is no image distortion.

* The frame of glassescan block your side / peripheral vision.

* It’s annoying when eyeglasses steam up when you come from the cold outside into a warm room.

* Sometimes contact lenses are the only solution for people who need vastly different lenses for each eye.

* An injured cornea can heal faster when its protected by contact lenses.

How Do You Go About Getting Contacts?

The next step, if you’re interested, is to to see your eye care professional to get a prescription for contact lenses since you can’t order contacts with a prescription for glasses. You’ll go through some easy vision tests that only take about 15 minutes or so. You should also get the test for Glaucoma, which is the one where there’s a tiny puff of air that gets shot into your eye. Jennifer Aniston’s character, Rachel, from Friends made a big deal about it, but it’s actually no big deal at all.

Lasik Doctors Should Not Make You Feel Nervous

Is it cheaper for someone living in the United States to go to Canada to have Lasike surgery done? Anyone who is on a budget might be trying to find a place to get it performed cheaper and yet still have a reliable doctor. Some people have gone to Canada to have Lasik done because it was somewhat cheaper but that was before the Canadian dollar got strong.

Lets suppose you are considering lasik surgery in Seattle surgery and you have heard that it was cheaper in Canada. Canada is a short 2 hour drive from Seattle so it might be worth the trip. Unfortunately, in the past couple of years the Canadian dollar has overtaken the US dollar Lasik in Canada has gotten more expensive. Then, if you add in your gas and other travel expenses it becomes clear Lasik in Canada isn’t as cheap as it once was. Also, as the technology gets better and the procedure has become refined, the price of Lasik has gone down in the US as well.

If you are looking for places in the U.S to get laser eye surgery, your best bet is probably by word of mouth. There are usually lots of laser doctors in the major cities and that makes it difficult to choose the doctor that might be the right one for you. If you have any friends who have experience with laser eye surgery you should ask them about their experiences and what doctors they used. If you can get a lot of feedback on some of the Lasik surgeons, you will be better able to pick the one that others have felt the most comfortable with.

Lasik eye surgery has become very safe and yet it still is a nerve racking experience for many people. This is because it deals with the eyes which are so important to our way of life. Lasik eye surgery is a choice people make and so it is smart to take your time and pick a doctor that you feel comfortable with. It makes no sense to have it done by someone like or feel right about. Asking your friends about the doctors they used will help steer you in the right direction in making a good choice.

Your eyesight is obviously a very important part of your life and you should not risk it in any way. If you don’t like the first doctor you go to, there are surely many more in whatever city you live in so keep on looking till you find the one you like.

Laser Eye Surgery Guide

Friday, May 1st, 2009
by Warren Rose

Eye surgery is not as easy as doctors tell us. In the first place, we perceive our eyes as fragile. And this is the truth. So many people in the world are going blind, that one really has to be very careful what clinic they choose to have this surgery done.

PRK signifies photorefractive keratectomy. The procedure implies the the cutting of a small fraction from the cornea, resulting in reshaping it. In this manner myopia and hyperopia are corrected, making it possible to give up the prescription glasses for so many patients.

Lasik is working on the same principle as PRK, but the layer removed from the cornea is not superficial, but the next layer under the surface. Then the superficial layer is put back in place, permitting the eye to heal.

Both procedures are done with excimer lasers. All lasers for Lasik or for any other type of medical intervention have to be FDA approved. This is how patients safety is secured. This is how the state show they are preoccupied to have a healthy population.

Vision defects can be settled through any of the two types of eye surgery. The doctors will consult each candidate individually, then indicating one operation or another. Every now and then, they could settle that the subject should not be exposed to any kind of eye surgery at all.

Mistakes in laser eye surgery can be very costly, as they may affect the patients vision for ever. Choosing doctors only after thorough investigations will reduce the exposure to such medical risks.

Eye surgery professionals say that the eyes heal quicker after Lasik than after PRK. These doctors probably have their conclusions, but there’s hardly any medical proof to endorse this claim. Each of us is unique, therefore healing is a personal process. It can go well, but sometimes it could take very long. We’ll see as we live.
