Dr. Kirzner has achieved a high success rate with his patients after only one treatment. It is important to note, however, that due to the individual’s prescription level an enhancement for some patients may be necessary. Of those who require one or more additional procedures, the cost of retreatment – enhancement is covered by our Lifetime Commitment Policy, excluding medications. In some cases, you may be required to pay for a Tissue Saving card. Our surgeon will determine the need for a re-treatment three months following the initial LASIK procedure and six months following the initial PRK procedure, based on medical opinion and the patient’s recovery.
