PRK

Photorefractive keratectomy (PRK) is a laser surgery that reshapes the cornea to improve vision.

With photorefractive keratectomy (PRK), Henry Ford surgeons use advanced computer technology combined with the precision of the WaveLight excimer laser to treat nearsightedness, farsightedness and astigmatism.

PRK vs. LASIK

PRK is similar to LASIK , a common laser vision correction procedure that can reduce or eliminate the need for glasses or contact lenses. The main difference between PRK and LASIK is that PRK does not require creating a corneal flap. For this reason, PRK is often recommended for patients with thin corneas .

What happens during PRK surgery?

During PRK surgery:

• The epithelium – the cornea’s outermost layer – is partially or fully removed using diluted alcohol or a specialized brush.
• An excimer laser uses pulses of ultraviolet light to reshape the cornea for proper focusing.
• Only the outer layers of the cornea are affected, unlike LASIK, which also involves deeper layers.

Recovery and normal vision after PRK surgery

PRK surgery is generally not painful. Some patients report mild pressure or vibration during the procedure. After PRK:

• A protective contact lens bandage is placed on the eye to support healing and comfort.
• It typically takes 4 to 5 days for the epithelium to regrow.
• You may experience discomfort for several days, and recovery may take longer than with LASIK.
• Blurred vision is common during early healing.
• Your surgeon will guide you through the recovery process and set expectations.

Vision clarity and focus may fluctuate during the first several weeks after surgery. Most patients achieve stable vision within two to three months.

PRK and other refractive procedures

PRK is not right for everyone. Your Henry Ford ophthalmologist can help determine whether PRK or another type of refractive surgery — including LASIK or refractive lens exchange — is right for you.

CareCredit Financing

To make vision surgery more accessible, Henry Ford offers financing options, including the CareCredit® credit card , which can be used for PRK, LASIK and refractive lens exchange.
