If there is not enough corneal thickness or if there are corneal scars, PRK is the method of choice. This is where the surgeon will wipe off the epithelial cells and then reshape the stroma tissue without using any cornea in a flap creation. This preserves tissue or will help reduce or eliminate corneal scars. A clear “bandage” contact lens will be placed to help with comfort and smooth healing for 4-6 days, and we ask that you do not plan on driving during that time. Vision results are the same as with the flap creation, the difference is only the down time of 4 to 6 days versus one day. Afterward, the vision is equal between the two different methods.
