The last few years have seen sweeping change in the medical field by way of the revolution in vision, LASIK eye surgery. Many people with vision problems get excited at the thought of corrective surgery. But just what is LASIK eye surgery?
Refractive errors in the cornea are corrected by lasers in LASIK surgery. The laser precisely controls the tearing of the corneal tissue, reshaping the cornea and changing its focus. LASIK surgery is a very simple two step process:
- A slight, thin flap of tissue is created on the outside layer of the eye or cornea. The flap helps heal and provide comfort on the way to better vision.
- The doctor then folds open the flap on the inner cornea to correct the vision. Finally, the flap is closed to its original position and sealed with stitches.
The word LASIK stands for Laser-Assisted In Sutu Keratomieusis, a process which reshapes the cornea to refract light in the lens. While LASIK surgery isn’t close to perfect, it is a very viable and increasingly safe surgery.
Improvements have been made by government regulations regarding the types of lasers allowed for LASIK surgery. A good idea for those who are considering the surgery is to research the types of lasers used by local doctors during LASIK.
As improvements are made and doctors are regulated the cost of LASIK surgery continues to drop, making it a possibility for some who could only dream of such improvement a few years back. Some surgeries are referred to as “bladeless” or “custom” LASIK, meaning they are more efficient and tailored to the individual.
LASIK surgery is an exciting prospect to anyone who has suffered from vision problems in the past. However, much like buying a car or house, it is important to do your homework first.
