In PRK, the excimer laser application goes on the surface of the cornea rather than under a LASIK flap. The laser removes tissue directly from the exposed corneal surface to reshape the cornea.
When performed with custom wavefront-guided excimer laser treatment, PRK will typically produce the same excellent visual results as LASIK.
PRK differs from LASIK in that patients typically need more healing time to reach their full visual recovery. Patients who undergo PRK also describe more discomfort during the first few days after the procedure. Immediately after the procedure, a bandage contact lens is placed in the eye for 3- 5 days to enhance healing. In general, our PRK patients can expect to see an immediate improvement in their vision and a steady improvement over the first 5 to 10 days after surgery. On average, they are back to work and daily activities within several days.
