PRK, or photorefractive keratectomy, corrects your vision the same way LASIK does, by reshaping your cornea with an excimer laser. What makes PRK different is how the cornea is prepared for the laser treatment. With PRK, instead of using a femtosecond laser to make a flap, the surface cells of the cornea are removed with a special process and the treatment applied to that outer area of the cornea. PRK is commonly referred to as “surface ablation,” meaning a laser procedure that is applied to the surface of the cornea.
It’s important to know that the same wavefront guided or optimized custom excimer laser is used to correct your vision in PRK as that used in LASIK. Therefore the visual results are the same between the two. The difference being that there is a longer recovery time after PRK since the surface cells of the cornea must heal. PRK has it unique advantages in specific situations and might be a better choice for you in the long term. At Boghossian Vision, we use advanced diagnostic technology to determine if PRK is the safest and best choice for you.
