Refractive errors are one of the most common eye vision problems experienced by many people today. People with refractive eye problems cannot see clearly and use lenses and glasses prescribed by doctors. With modern science and advanced medical technology, treating these eye problems has become possible.
As compared to LASIK, PRK surgery has a longer recovery procedure but is as effective as LASIK.
What are refractive errors?
In refractive error problems, you have a blurry and hazy vision. PRK laser surgery can treat and correct refractive eye problems. Nearsightedness, Farsightedness, and Astigmatism are examples of refractive eye problems.
How PRK surgery is performed?
The whole PRK procedure takes 5 to 10 minutes on each eye. To prevent your eye from blinking, an eye holder will be used. The procedure starts with the removal of the top layer of the cornea. After the removal of corneal cells, the reshaping of the cornea is performed by using an excimer laser. Then, a non-prescription lens will be put on each eye. This is a form of bandage which is placed on the eyes for protection. The doctor will remove it after 3 or 5 days. By the time, your eye will regenerate a thin layer of superficial cells.
It is a quick procedure, and you may return to your office or home on the same day.
Are you the right candidate for PRK surgery?
If your doctor has told you not to undergo Lasik laser surgery because of the thin cornea, you may consider PRK surgery. PRK surgery is an ideal vision correction treatment for people who have refractive eye problems (myopia, hyperopia, astigmatism). Before undergoing PRK surgery, discuss with your doctor about the risk and benefits of the surgery.
Below are some points that may qualify you as a good candidate for PRK surgery:
- You don’t have an eye infection or eye injuries.
- A cataract affecting vision
- You should be minimum of 18 years old
- No pregnancy
- Advanced glaucoma
- You must be healthy overall.
- You must have healthy eyes.
- You must not have dry eye syndrome.
- You must have the same eye prescription in the last year.
- You should not have keratoconus.
How the recovery period is like?
PRK recovery takes a lot longer than LASIK. Some people experience discomfort and pain in the initial days after surgery. But it is temporary. You must have your recovery process monitored by your doctor to check on the recovery. Generally, you may have to wait for three months to get a completely clear vision.
