Overview of Photorefractive Keratectomy (PRK)

Photorefractive Keratectomy (PRK) is a laser eye surgery that reshapes the cornea to improve vision and reduce or even eliminate the need for glasses or contact lenses. It is a safe outpatient procedure that takes only a few minutes per eye and is ideal for patients who are not candidates for flap-based surgeries. With a long history of successful outcomes, PRK remains a trusted option for many seeking effective vision correction.

The Step-by-Step PRK Procedure

Numbing the Eye

Your experience begins with the application of anesthetic eye drops to ensure you feel no pain throughout the surgery.

Eyelid Management

An instrument is used to gently hold your eyelid open while you focus on a target light. This allows our refractive eye surgeon to work precisely on your cornea.

Removal of the Corneal Epithelium

The surgeon delicately removes the outer layer of the cornea, known as the epithelium. This layer, which is as thin as a human hair, is necessary to be removed in order to access the stroma, where reshaping will occur.

Laser Reshaping

An excimer laser then delivers controlled pulses of cool ultraviolet light; these precise bursts remove minuscule amounts of tissue from the cornea to achieve the proper curvature required for clear vision. The adjustments can be made with extreme accuracy, down to one-thousandth of a millimeter.

Bandage Contact Lens Placement

After the reshaping process, a protective bandage contact lens is placed over your eye. This lens helps shield the cornea as the epithelial cells begin to regenerate over the next few days.

Each of these steps is designed to maximize safety and precision, so you know you’re in good hands throughout your PRK treatment.

What to Expect During Your PRK Procedure

Sensations During Surgery

You may feel a slight pressure during the procedure, but thanks to the numbing drops, any discomfort is minimal. The entire process for each eye typically takes between five and fifteen minutes.

The Role of the Excimer Laser

This laser is a remarkably precise tool that targets only the specific areas of your cornea requiring reshaping, without affecting surrounding tissues. This precision contributes to the overall safety and effectiveness of PRK.

A Painless Experience

Since the procedure is done with the aid of anesthetic drops, it is described as generally painless. Most patients are astounded by how smooth and controlled the process is.

Your experience during the procedure is carefully managed to ensure that you remain comfortable and secure, reinforcing the trust you place in our refractive eye surgeon.

Recovery After PRK: What You Need to Know

Bandage Contact Lens Care

Once the excimer laser has completed its work, a bandage contact lens is placed on your eye. This protective covering helps reduce discomfort while your corneal epithelial cells regrow. Typically, the lens is removed after three to five days, once enough new tissue has formed.

Healing Sensations

As the epithelium heals, you might experience mild to moderate discomfort that resembles having a foreign object in your eye. Common experiences include tearing, light sensitivity, and a transient blurring of vision. These symptoms usually peak around the second or third day after surgery.

Vision Fluctuation

In the days following the surgery, you may notice gradual changes in your vision. For many patients, the initial clarity ranges from 20/30 to 20/50, depending on the extent of the treatment. As the new epithelial layer continues to smooth out, which takes about four to six weeks, your vision will steadily improve.

Long-Term Stability

Though it may take several weeks for you to notice the full benefits, your vision is typically considered stable by three to six months after PRK. If necessary, our refractive eye surgeon may discuss a secondary procedure to adjust and enhance your outcome.

The recovery period after PRK is a gradual process, and while patience is required, the long-term results are well worth the brief period of healing and adjustment.

Comparing PRK with Flap-Based Procedures

PRK and Its Distinctive Features

  • No Corneal Flap: PRK avoids creating a flap, which means the outer layer of your cornea is removed rather than being lifted and repositioned. This eliminates risks that can be associated with flap-related complications such as its dislocation after trauma.
  • Greater Suitability for Thin Corneas: For patients with thinner corneas or irregular corneal shapes, PRK offers a safer alternative since more of the corneal structure remains intact after surgery.
  • Reduced Risk of Dry Eye: Since the procedure does not involve cutting through as many nerves as LASIK does, there tends to be a more rapid recovery of normal corneal nerve function, which in turn minimizes issues with dry eye symptoms.
  • Enhanced Safety for Active Lifestyles: Those who work or participate in sports where eye trauma is a possibility may find PRK a more secure option since there is no flap to be dislodged in the event of an impact.

How LASIK Differs

  • Flap Creation: LASIK involves the use of a microkeratome or a laser to create a corneal flap. Once the flap is lifted, the excimer laser reshapes the underlying tissue, after which the flap is replaced, helping to protect the cornea as it heals.
  • Swift Initial Recovery: Patients undergoing LASIK often experience a faster initial recovery, with many noticing improved vision within a day.
  • Potential Flap Complications: Although rare, issues such as a dislodged or elevated flap can occur, especially if the eye sustains trauma after surgery.

Choosing between PRK and LASIK depends largely on your eye’s health, corneal thickness, and lifestyle considerations. Our refractive eye surgeon takes careful measurements and evaluates your vision needs during a comprehensive exam to determine the procedure that is best suited to you.

Common Questions

The PRK surgery itself typically lasts between five and fifteen minutes per eye.
Most patients report that the procedure is painless due to anesthetic drops, with only a slight sensation of pressure.
Recovery from PRK generally takes longer than flap-based procedures, with full stabilization typically occurring in three to six months.
You will have a bandage contact lens placed over your eye, and may experience tearing, light sensitivity, and some blurring initially.
Yes, PRK is often preferred as it avoids creating a flap, which can contribute to dry eye symptoms.
Enhancement procedures can be performed if necessary, following a similar process to the original surgery.
