Eye laser surgery can be an effective way to correct certain types of vision problems. There are several different types of laser eye surgery, including LASIK, PRK, and SMILE. These procedures use a laser to reshape the cornea, which is the clear front part of the eye, to improve vision.
LASIK is the most commonly performed laser eye surgery. During the procedure, a thin flap is created in the cornea, and the laser is used to reshape the underlying tissue. The flap is then repositioned, and the eye is allowed to heal. LASIK is often used to correct nearsightedness, farsightedness, and astigmatism.
PRK (photorefractive keratectomy) is another type of laser eye surgery that can be used to correct vision problems. During the procedure, the top layer of the cornea is removed, and the laser is used to reshape the underlying tissue. The eye is then allowed to heal over several days to weeks. PRK is often used to correct nearsightedness, farsightedness, and astigmatism, but it may be recommended for people who are not good candidates for LASIK.
SMILE (small incision lenticule extraction) is a newer type of laser eye surgery that uses a laser to create a small, precise incision in the cornea. The laser is then used to create a small lens-shaped piece of tissue, which is removed through the incision. SMILE is often used to correct nearsightedness, but it may also be effective for correcting astigmatism.
Laser eye surgery is generally safe and effective, but it may not be suitable for everyone. It is important to talk to a qualified eye doctor or surgeon to determine whether you are a good candidate for laser eye surgery and which type of procedure is best for you.
