Does PRK Last Forever?
PRK (Photorefractive Keratectomy) was the first ever laser vision correction technique performed on the eyes. PRK is often viewed as the traditional LASIK alternative for those who do not meet the criteria for LASIK, typically patients with thin corneas. PRK surgery corrects nearsightedness, farsightedness and astigmatism without creating a flap in the cornea. While recovery time varies between LASIK and PRK, LASIK takes a few days or less to see clearly while PRK can take an average of a month for healing. Both procedures, when performed by a licensed and experienced surgeon, boast a high patient satisfaction rate with permanent results.
Does PRK last forever? As the excimer laser used in the procedure permanently reshapes the cornea, the newly created shape will last forever. The subsequent clear vision should remain as well. PRK, or any refractive corrective surgery, does not guarantee that there will not be any changes in vision in the years following surgery due to natural aging of the eyes or any optical conditions that may arise in the future. For most people, PRK improved eyesight lasts forever.
PRK procedures require a series of appointments to ensure you receive the most optimal results possible. Laser eye surgery technology helps surgeons by scanning the eye’s surface to create a detailed map, known as topography. This allows the surgeon to plan your PRK procedure accordingly. With PRK, the surgeon will gently swab away the thin outer layer of the cornea known as the epithelium. Next, the excimer laser will alter the shape of the cornea and correct any refractive errors. Patients can be surprised to learn that recovery includes vision changes. Almost immediately, patients notice very clear vision. But because the top layer of the corner was removed, it takes about a week for those surface cells to grow back. As this happens, vision can worsen, appearing blurry. This occurrence is normal and common. Vision will become clear again within a few weeks post-surgery once those cells smooth out.
