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 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.
It is possible to go home right after surgery. It is recommended to rest and if possible take a nap, because the eyes may sting a little bit.
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.
A LASIK laser treatment can also not prevent the age-related long-sightedness that all (even normally sighted people) will experience.
