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.
LASIK technique is a further development of the older PRK laser surgery. Both operations are done by removing the outer cornea layer, so the laser can remove the tissue. The difference is that while the PRK eye surgery scrapes the outer layer of the cornea away, the LASIK surgery will cut a flap in the cornea that can bend. After the surgery the flap will be 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.
It is possible to leave the operating room right after the surgery. The eyes may sting a little bit, so it is advised to rest for the rest of the day. A nap can also help.
Most people will already at that time feel that their sight has improved. Over the next weeks will stabilize.
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 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 LASIK surgery can also not prevent the natural age-related long-sightedness that even normally sighted people will experience.
