Why You Do Not Have To Fear A Lasik Surgery

Thursday, January 7th, 2010

Lasik eye surgery is a big thing for many people; and most of them do not dare to ask all the relevant questions. The Lasik surgery is normally not discussed in details; so many people have an (actually) unnecessary fear. Here in this article those details are discussed.

One of the most common fear, both when it comes to the Lasik surgery and any operation in general is the fear of pain during and after the surgery. When a Lasik surgery is performed the eye is applied with numbing drops. The patient also receives a mild sedative so they can relax and feel comfortable. So even though you may feel a minor pressure to the eye, it is relatively pain free

The next step is the actually eye surgery, where a laser is used to reshape the cornea. It is a common fear that they laser is shot directly into the eye, or that you might look away, so the eye is hurt. But the laser has a tracking system that makes sure that it is only use when the eye is in the correct position. And further more the laser is actually only used for ten to fifteen seconds for each eye.

Another general fear for people contemplating a medical procedure is fear of “the scalpel”. Any Lasik procedure uses only a very small microkeratome blade to approach the eye, or some more recent Lasik innovations have the laser itself created the flap and avoid using any hard surface at all. There is no reason to be concerned about a scalpel, for the Lasik physician does not use one.

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 is the risk of a serious permanent complication less than one percent. And the risk of any permanent complication, including minor complications like as light halos, is less than 3 percent. It is extremely rare that the sight isn’t improved after a Lasik surgery.

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.

If the thought of actually seeing the Lasik physician’s hand approaching your eye is bothersome, be comforted that the surgeon applies drops to the eye that blacks out the vision in that eye for ten to fifteen seconds, which is long enough for the procedure to be done for that eye.

What You Need To Know About LASIK Surgery

Wednesday, November 4th, 2009

LASIK is the most popular type of eye surgery today. It is at the same time fast, efficient and gentle. And the complications of are rare. For most people a LASIK surgery is a good solution to improve their sight in the cases of nearsightedness, farsightedness and/or astigmatism.

LASIK technique is a further development of the older PRK laser surgery. Both operations are done by removing the outer cornea layer, so the laser can remove the tissue. The difference is that while the PRK eye surgery scrapes the outer layer of the cornea away, the LASIK surgery will cut a flap in the cornea that can bend. After the surgery the flap will be put back again.

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 operation only takes between 30 seconds and two minutes. A laser specially designed for operating in the eye’s sensitive tissues will be used. After the operation the flap is put back in place.

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.

Right after the operation the sight will have improved for most people. Over the next weeks it will be stabilized.

After the eye surgery the eyes can feel a little dry. It is therefore recommended to drip them with a little salt water.

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.

A LASIK laser treatment can also not prevent the age-related long-sightedness that all (even normally sighted people) will experience.
