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.

What To Take Care Of If You Want To Have Eye Laser Surgery

Wednesday, April 29th, 2009

Undergoing surgery on eyes is not as easy as doctors say. First of all, we think of our eyes as being very delicate. And that’s the reality. There are so many accidents that can cause, that everybody ought to carefully consider what clinic they choose to treat their sight.

PRK stands for photo refractive keratectomy. The surgery is basically the the cutting of a thin portion from the cornea, resulting in reshaping it. In this way vision defects are corrected, making it possible a glasses-free living for so many persons.

Lasik is working on the same principle as PRK, but the portion removed from the cornea is not the surface one, but a deeper portion. Then the upper portion of cornea is put back in place, permitting the eye to heal the wound.

Lasik and PRK are both operated with excimer lasers. All lasers for PRK or for any other medical surgery must be FDA approved. This is how patients safety is secured. This is how the government is a signal they are preoccupied to have a healthy population.

Myopia and hyperopia can both be settled through either Lasik or PRK surgery. The doctors will examine each candidate individually, then indicating one operation or another. At times, they may even claim that the sufferer should not be undergoing any surgery procedure.

Mistakes in precision surgery could be dangerous, as they may impair the person who suffered the surgery irreversibly. Deciding for the eye surgeon only after informing yourself very well will diminish the danger of meeting the not-so-specialist surgeon.

It has been noticed by some eye surgeons that patients need less recovery days after Lasik than after PRK. However, as nobody made the hard evidence of this fact yet, all we have to say is that there are cases in which one type of surgery is better than the other. This is why we need to go for specialist advice before doing anything.
