Why is there more pain after PRK? The cornea has more nerves per unit area than any other part of the body other than the brain. The surface cells that cover the free nerve endings are removed during PRK resulting in more discomfort after PRK than LASIK. The median pain score is a 3 on scale of 1 to 10 with 10 being severe pain. Some patients have minimal or no pain while rarely patients may experience significant discomfort. The pain lasts for 24hrs or less in the overwhelming majority of patients. Dr. Kornmehl uses a special pain regiment to make minimize discomfort for the first 24 hours.
