Understanding PRK

Photorefractive Keratectomy (PRK)

Understanding PRK

This section explains what PRK is, how it compares with LASIK, and why it remains a trusted choice for many patients.

PRK is a laser eye surgery that reshapes the cornea, the clear front surface of the eye, to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. Instead of creating a corneal flap, the surgeon gently removes the thin outer layer of cells, which then regrows during healing.

Both PRK and LASIK use an excimer laser to reshape the cornea, but LASIK involves a hinged flap while PRK does not. By avoiding a flap, PRK eliminates flap-related risks and can be safer for certain eye shapes and lifestyles.

Using computer-guided technology, the laser removes microscopic layers of corneal tissue to create an ideal curvature that focuses light correctly onto the retina. This precise change permanently addresses the underlying refractive error.

Approved by the FDA in 1995, PRK has nearly three decades of clinical data supporting its long-term safety and effectiveness. Most patients maintain their corrected vision for many years, although natural aging can still lead to presbyopia or cataracts later in life.

Why PRK May Be Recommended Over LASIK

Why PRK May Be Recommended Over LASIK

Not every eye is suited for LASIK. In several situations, PRK offers a safer or more effective alternative.

When the cornea is too thin or irregular for a safe LASIK flap, PRK preserves more tissue and maintains structural integrity.

Military personnel, athletes, and others exposed to eye trauma often choose PRK because there is no flap that could be dislodged by impact.

Because PRK disrupts fewer corneal nerves than LASIK, it is less likely to worsen pre-existing dry eye and is often preferred for patients who already struggle with ocular dryness.

For some patients with strong prescriptions, PRK can safely remove enough tissue for correction without the added thickness needed for a LASIK flap.

In conditions like Epithelial Basement Membrane Dystrophy, removing the epithelium during PRK can improve both vision and corneal health while avoiding flap-related complications.

Patients who have undergone procedures such as Radial Keratotomy or corneal transplants may benefit from PRK because it does not interfere with earlier incisions or grafts.

Some people simply prefer to eliminate the small risk of flap issues altogether. PRK provides similar visual outcomes without any flap-specific concerns.

Your PRK Journey

Your PRK Journey

From consultation through recovery, our goal is to create a comfortable and informed experience.

An in-depth eye examination maps your cornea and confirms your prescription. This visit allows you and your surgeon to discuss goals, review findings, and design a personalized plan.

The surgery takes about five to ten minutes per eye. Numbing drops keep you comfortable while you focus on a target light and the laser reshapes the cornea.

Healing is gradual because the surface cells must regenerate. Most patients rest for several days, notice vision improving over the first week, and achieve stable clarity within a few months.

Unstable prescriptions, certain autoimmune diseases, active eye disorders such as keratoconus, and pregnancy or nursing can preclude surgery. A thorough evaluation ensures the procedure is safe for each patient.

Frequently Asked Questions

Here are answers to common questions patients ask about PRK.

The eye is completely numbed during surgery, so you feel pressure but not pain. Mild discomfort, light sensitivity, and a gritty sensation are normal for a few days afterward and are managed with drops and rest.

The corneal reshaping is permanent. Age-related changes such as presbyopia or cataracts can still occur decades later and may require separate treatment.

You will need a driver on surgery day. Most people can drive five to seven days later, once vision meets legal standards and the surgeon confirms it is safe.

Yes. Presbyopia affects nearly everyone in their 40s or 50s, regardless of whether they have had PRK, LASIK, or no surgery at all.

PRK is often preferred for patients with dry eye because it spares more corneal nerves, reducing the likelihood of worsening dryness during recovery.

Factors such as thin corneas, high trauma risk, or certain corneal conditions can make PRK the safer choice while providing similar visual results.

An eyelid speculum keeps the eye open, and advanced eye-tracking technology follows even tiny movements, pausing the laser if needed to ensure precise treatment.

Insurance typically classifies PRK as elective and does not cover it. Costs vary by prescription and technology used, and many patients use financing plans or pre-tax accounts such as HSA or FSA to manage expenses.

Most patients plan for five to seven days away from work. Initial rest is important, and screen time should be kept minimal until vision clears and comfort improves.

Yes. The excimer laser can precisely smooth corneal irregularities that cause astigmatism, often eliminating or greatly reducing the need for corrective lenses.

No medical procedure can guarantee exact outcomes. However, modern PRK achieves 20/40 or better in over 95 percent of patients, and a majority reach 20/20 or better, depending on prescription and healing.
