Everything About LASIK Surgery
The most popular eye surgery today is LASIK surgery. It is efficient, fast, very gentle and with few complications. For most people the LASIK surgery can help them no matter if they are nearsighted, farsighted and have 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 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 LASIK laser surgery provides a permanent sight improvement. Similar previous bad eyesight will not now return. But the surgery does not prevent a possible, natural change of sight in the future. It is therefore very important that the sight is stable when operated.
A LASIK laser treatment can also not prevent the age-related long-sightedness that all (even normally sighted people) will experience.
