Photorefractive keratectomy (PRK) is a laser eye surgery that can help correct vision issues. It is an effective procedure for treating conditions such as nearsightedness, farsightedness, and astigmatism. PRK may be a suitable choice if you are unable to undergo LASIK surgery due to dry eyes or unusually shaped corneas. Here is more information about PRK and who needs it:
What Is Photorefractive Keratectomy?
PRK surgery uses a laser device to make minor alterations to the eye. It reshapes the cornea to alter how light is bent and improve your vision. The preparation for this laser eye surgery begins with a thorough eye assessment to make sure there are no conditions that could affect the procedure’s success. The surgeon takes precise measurements of the eye’s surface, mapping the cornea in detail. After this, they numb the eyes to facilitate the removal of the epithelium, the cornea’s outermost layer.
During the procedure, the surgeon removes the outer layer of the cornea, which will regenerate a few days after the surgery. The reshaping process uses an excimer laser, resulting in permanent changes to the cornea. A contact lens is placed on the cornea to protect the eye as it heals. Vision typically improves over the course of a few weeks as the eye recovers.
Who Is the Ideal Candidate for PRK?
PRK can be an effective alternative if you are disqualified from LASIK due to corneal thickness or specific medical conditions. You may be a good candidate for this procedure if you have thin corneas, which can make LASIK risky because of the flap creation involved. PRK is also a better option if you have abnormal corneal surfaces that could make it difficult for surgeons to create an even flap. The absence of a flap may make PRK appealing to those with active lifestyles or jobs that pose a higher risk of eye injury.
Before undergoing PRK, your eyes should be healthy and free from severe dry eye disease, allergies, or uncontrolled corneal conditions. Cataracts and glaucoma are other conditions your doctor will look for before recommending eye surgery. A thorough consultation, including eye tests, will determine whether PRK is a suitable option for your vision correction needs.
What Should Patients Expect During PRK Recovery?
Recovery from PRK may take longer than some other vision correction surgeries. During recovery, prescribed medications can treat surgical site sensitivity and minor discomfort immediately after the operation. A natural variation in vision may occur during the first weeks as the cornea heals from the procedure. Visible improvements in vision may begin by the first month, though complete stabilization can take several months.
Attend all scheduled check-up sessions to track recovery progress and promote proper healing. Your eye surgeon will educate you about recovery requirements, which can include limiting physical activity and avoiding excessive smoke and dust to protect your eyes. Take any prescribed medications as instructed, and wear your bandage contact lenses as recommended. While PRK may require more recovery time than LASIK, it offers lasting vision correction, making it a suitable option for those seeking long-term vision improvement.
