PRK Photo-Refractive Keratectomy
PRK, Photo-Refractive Keratectomy, is the process of using the excimer laser to reshape the cornea so light is focused naturally on the retina. PRK was the first procedure to use the excimer laser to treat many types of refractive errors and is still the procedure of choice for certain patients.
During PRK, the excimer laser uses a cool ultraviolet light beam to precisely remove very tiny bits of tissue from the surface of the cornea in order to reshape it. Once the cornea is reshaped, it works better to focus light into the eye and onto the retina, providing clearer vision than before.
To see if you are a candidate for PRK, please contact Chu Vision Institute to schedule a consultation.

After numbing the eye with anesthetic drops, the physician gently removes the epithelium, a thin layer of tissue covering the cornea.
The excimer laser applies a cool beam of light, which gently reshapes the cornea allowing ../images to be more sharply focused by the retina to correct the individual refractive error.
After the cornea is reshaped, the epithelium is allowed to grow back in naturally and takes only 3-5 days to heal.
