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.
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.
It only takes a few minutes to perform the the surgery. The eye will be dripped with anesthetics and most people will not feel any pain at all. When the eye is anaesthetized the cut in the cornea can be made and the laser surgery can be done.
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.
For most people the sight will have improved right after the operation. It will then stabilize over the next weeks.
Normally the eye will be a little dry after the surgery, so it is advised 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.
The age-related long-sightedness that all people will experience can also not be prevented by a LASIK operation.
