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.
It takes between 30 seconds and two minutes to perform the actual laser operation. A specifically designed laser called an Excimer laser will be used for the operation for the operation in the sensitive tissue. After the surgery the corneal flap will be 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.
The eyes can feel a little dry after the operation. Dripping them with salt water might help.
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 age-related long-sightedness that all people will experience can also not be prevented by a LASIK operation.
