PRK

PRK vs LASIK Video


PRK (Photorefractive Keratectomy) and LASIK are both similar and different in the procedure as well as the outcome. Both use the excimer laser, and both can produce outstanding results in correcting refractive error with somewhat different approaches.

PRK is a refractive surgery technique to reshape the surface of the cornea, while LASIK reshapes the inner layers of the cornea. With PRK, healing time, and the time to achieve the maximum benefits from the procedure, is usually longer than with LASIK.

PRK Procedure

PRK Overview


As is true with LASIK, PRK is painless and actually takes just a few minutes to perform.

  • The excimer laser is extremely precise: in the PRK procedure, it is used on about 10% of the cornea
  • A topical anesthetic in the form of eye drops is used to numb the eye, permitting the patient to be fully awake but pain free during the brief operation.
  • Typically, PRK patients experience some discomfort and a “gritty” feeling for 24 to 48 hours after the procedure
  • Medication is provided to relieve this or any other discomfort

For most patients, the final outcome of PRK takes time to achieve. You can expect your vision to be blurry while your eye heals. Improved vision is typically noticed in three to five days following treatment. The Surgeon who performs your operation will monitor your progress after surgery at regular eye checkups.
