Refractive eye surgery is a type of surgery that can help improve vision by correcting problems like nearsightedness, farsightedness, and astigmatism. These problems are often caused by a misshapen cornea, which is the clear front part of the eye that helps focus light.
During the surgery, a special tool is used to reshape the cornea so that it can better focus light and improve vision. There are different types of refractive eye surgery, but some of the most common ones include LASIK, PRK, and SMILE.
LASIK is a type of refractive eye surgery where a flap is created in the cornea, and then a laser is used to reshape the cornea underneath the flap. Once the cornea has been reshaped, the flap is then put back in place. PRK is similar to LASIK, but instead of creating a flap, the top layer of the cornea is removed and then the laser is used to reshape the cornea. SMILE is a newer type of refractive eye surgery where a small incision is made in the cornea, and then a laser is used to reshape the cornea through the incision.
Refractive eye surgery is typically performed on an outpatient basis, which means that you can go home the same day as the surgery. Before the surgery, you will need to have a thorough eye exam to determine if you are a good candidate for the procedure. You should also tell your doctor about any medical conditions you have and any medications you are taking.
During the surgery, you will be given local anesthesia to numb your eyes, so you won’t feel any pain. You may also be given a sedative to help you relax. The actual surgery usually takes less than 30 minutes, and most people are able to go back to work or resume their normal activities within a few days to a week after the surgery.
After the surgery, you may experience some discomfort, such as dryness, itching, or mild pain in your eyes. Your doctor may prescribe eye drops or other medications to help manage these symptoms. You will also need to avoid rubbing your eyes and taking part in any strenuous activities for a few weeks after the surgery.
While refractive eye surgery can be a great way to improve your vision, it’s important to remember that it does carry some risks. In rare cases, people may experience complications like infections, corneal scarring, or even a loss of vision. It’s important to talk to your doctor about the risks and benefits of the procedure before deciding if it’s right for you.
Overall, refractive eye surgery is a safe and effective way to correct vision problems and reduce your dependence on glasses or contact lenses. If you’re interested in the procedure, be sure to talk to your eye doctor to determine if you’re a good candidate and to learn more about the different types of surgery available.
