subject: Everything About Lasik Surgery [print this page] 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 LASIK surgery is a new and better form of the old PRK surgery method. In both cases the outer cornea layer is removed, so the laser can operate directly at the tissue. But when performing a PRK surgery the outer layer is scraped away, while the LASIK operation more gently cuts a flap in the cornea. The flap can be bent, the laser operation performed and the flap is 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 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.
For most people the sight will have improved right after the operation. It will then stabilize over the next weeks.
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 show that a permanent sight improvement is provided after a LASIK surgery. And previous bad eyesight will not come back. But it is not possible to prevent a possible, natural change of sight in the future with operation. So it is very important not to perform the operation before the sight is stable.
The LASIK surgery can also not prevent the natural age-related long-sightedness that even normally sighted people will experience.
