Every eye is different, so different procedures exist to treat various conditions more efficiently than others. The most common laser surgeries currently performed are LASIK and PRK.
Laser in-situ keratomileusis, or LASIK, is the most commonly performed refractive surgery to correct vision problems. The procedure involves using an excimer laser to make a small flap in the cornea’s epithelium, revealing the corneal tissue beneath.
The laser is then used to reshape the cornea to correct the refractive error. The flap is then replaced over the cornea to act as a natural bandage.
Photorefractive keratectomy, or PRK, is a similar procedure to LASIK that is commonly used to correct myopia, hyperopia, and astigmatism. PRK is a method often used for thin corneas for individuals due to the specifics of the surgery.
A laser, blade, solution, or brush is used to remove the epithelium, allowing access to the corneal tissue. A laser will then be used to reshape the cornea to correct your refractive error. You’ll then be fitted with a bandage contact lens to help promote healing for the following few days.
PRK may cause significant discomfort for the following few days following the procedure. You may be prescribed over-the-counter medication to help with any pain.
