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.
