There are billions of people in the U.S. who must wear aids for their vision. This can include either glasses or contacts, both of which can cost a lot of money. You either have to pay to get replacements when they are defective or pay to get a new batch or model routinely because your prescription changes. However, there is another option for those people who want clear vision, but don’t want to have to keep shelling out money, LASIK eye surgery.
What is LASIK?
LASIK eye surgery is a form of refractive surgery that’s used to correct the vision in patients who have poor eyesight. It can be used to fix several different vision problems, like nearsightedness, farsightedness, and astigmatism. LASIK is an excellent alternative to having to wear glasses or contacts because usually one surgery is enough to get the job done and restore 20/25 vision or better in the patient.
How Does it Work?
To understand the difference between LASIK and other vision correction surgeries, we need to understand what happens during the process. The cornea in your eye is basically a thin sort of film that helps to refract light as it enters. If your cornea is healthy and has a good shape, the light gets bent correctly and hits the inside of the eye in the right place. If not, then the light bounces and causes your vision to get blurry.
LASIK surgery is used to correct this corneal light refraction process. The surgeon uses a very precise laser to target the cornea, create a flap in it, then help reshape it, so it’s better designed for light refraction. If everything goes well, the patient feels no pain, and the process is completed within a few minutes for each eye.
Other Vision Correction Surgeries
Aside from LASIK and laser eye surgery, there are other options for eye surgery that may be better suited for you. There is the PRK procedure, otherwise known as photorefractive kerectomy. In this surgery, the process is similar, except there’s no incision made on the patient’s cornea. This process is a good option for those patients who don’t qualify for LASIK because of their dry eyes or other health conditions. It is also recommended for military personnel because there is no incision made in the cornea.
There is also the LASEK procedure. This is another process that’s similar to LASIK, except that the surgeon doesn’t remove as much of the cornea as in the LASIK procedure.
