What is the difference between LASIK and PRK (Lasik vs PRK)?
LASIK (Laser Assisted In-situ Keratomileusis): A thin flap is created that consists of the first layer (epithelium) and a small amount of the second layer (stroma). The flap is gently folded back by the surgeon to expose the majority of the stromal layer, which is then reshaped with the laser to change a person’s prescription. During laser treatment, which usually takes 10 to 60 seconds, any fine eye movements are tracked with a sophisticated tracking system, and there is no sensation of pain or discomfort. The flap is then laid back into place. Because most of the surface layer of cornea is replaced in its original position, very little surface area needs to “fill in” and recovery is rapid. Most people see well the day after surgery. PRK (Photorefractive Keratectomy or Advanced Surface Ablation): The second layer of the cornea (stroma) is exposed for laser treatment by removing the first layer (epithelium) over the area to be treated. Laser pulses are then applied to the surface of th
