Every procedure has risks involved. With laser treatment, we take every measure to protect your vision by placing special contact lenses to prevent the laser beam from injuring your eye. We also prescribe an antiviral medication prior to surgery to avoid a herpetic outbreak following the treatment. Aside from feeling like a mild sunburn for a few hours after the laser treatment, the pain is minimal. The pain would typically be a sign of a breakthrough herpetic outbreak, which is rare.
