In PRK, the soft outer covering of the eye is removed and the Excimer Laser is used to reshape the cornea to correct the ability of the eye to see in the distance or at near. Astigmatism can also be corrected with PRK.
A contact lens is placed on the eye and the soft outer covering grows back over 3 to 5 days. Medications to prevent infection and reduce inflammation are taken for about 2 months.
PRK is generally performed instead of Lasik if the cornea is very thin or dry. Sometimes if an eye is more likely to be bumped for example in someone who practices karate, PRK will be used instead of Lasik to correct a patient’s vision.
