23 Dec The Recovery Process After PRK Surgery
Photorefractive keratectomy (PRK) is a type of laser eye surgery that corrects vision problems such as nearsightedness, farsightedness, and astigmatism. It was the first kind of laser eye surgery for vision correction and preceded the more widely known LASIK procedure. PRK reshapes the cornea, the clear front part of the eye, allowing light to enter the eye correctly for clearer vision. The procedure offers a long-term solution for many individuals who wear glasses or contact lenses. Here’s more information on PRK surgery and what to expect during recovery:
How Is a Photorefractive Keratectomy Done?
The primary benefit of photorefractive keratectomy surgery is its ability to treat a wide range of refractive errors. It is often a suitable option for individuals with thin corneas who may not be candidates for LASIK. The procedure itself is relatively quick, typically lasting only about 15 minutes for both eyes.
A surgeon begins a PRK procedure by numbing the eye with anesthetic drops. The epithelium, which is the thin, protective outer layer of the cornea, is then gently removed to expose the underlying corneal tissue. An excimer laser, which is an ultraviolet light beam, is then used to precisely remove microscopic amounts of tissue and reshape the cornea. This reshaping corrects the refractive error, and the process is guided by a detailed map of the patient’s eye. A special bandage contact lens is placed over the eye to protect it as the epithelium regrows over the next several days.
How Does PRK Differ From LASIK?
While PRK and LASIK are laser eye surgeries that reshape the cornea, their primary difference lies in how the cornea is accessed. In PRK procedures, the surgeon completely removes the outer epithelial layer to reach the underlying corneal tissue. LASIK procedures involve creating a thin, hinged flap in the cornea with a laser or a microkeratome, and this flap is lifted to allow the laser to reshape the tissue underneath. The flap is then put back into place.
Because the epithelial layer is left intact in LASIK, the initial recovery is often faster and involves less discomfort than PRK. PRK eliminates the risk of flap-related complications, however, and may be recommended for:
- People With Certain Corneal Characteristics
- People in Professions With a High Risk of Eye Injury
What Is Recovery Like?
The recovery period for PRK is gradual, and vision will improve progressively over several weeks or months. Patients typically experience some discomfort, light sensitivity, and blurry vision in the first few days after the procedure as the epithelial layer heals. During the recovery period, it is imperative to protect your eyes. You should avoid rubbing your eyes, as this can disrupt the healing of the new epithelial layer. It is also recommended to stay away from dusty or smoky environments and to avoid getting soap or water directly in the eyes. You may be advised to wear sunglasses outdoors to protect your sensitive eyes from bright sunlight and UV radiation.
Antibiotic and Anti-inflammatory Medications
Following the surgery, you will be prescribed medicated eye drops to prevent infection and control inflammation. It is key to use these drops exactly as directed by your surgeon to support proper healing. The bandage contact lens placed on the eye after surgery will remain in place for several days. It helps reduce pain while the new epithelial cells grow.
Follow-up Appointments
Regular follow-up appointments are fundamental for your recovery, as your surgeon needs to monitor your healing and check your vision. The first appointment is usually scheduled shortly after surgery, with additional appointments occurring over the following weeks and months. These visits allow your surgeon to verify that your eye is healing correctly and to manage the post-operative care plan.
