FAQs about PRK

Here are some frequently asked questions about PRK:

1. What is PRK?

PRK, or Photorefractive Keratectomy, is a type of laser eye surgery used to correct vision problems. It involves reshaping the cornea using an excimer laser to improve how the eye focuses light.

2. How does PRK differ from LASIK?

PRK and LASIK are both laser eye surgeries, but they differ in the way the cornea is accessed. In the former, the outer layer of the cornea is removed, while in the latter, a flap is created and lifted before reshaping the cornea.

3. Am I a good candidate for PRK?

A thorough examination by an eye care specialist or an eye surgeon near you is necessary to determine if you are a suitable candidate for PRK. Generally, individuals with stable vision and healthy corneas, who are at least 18 years old, can be considered for the procedure.

4. What vision problems can PRK correct?

PRK is effective in correcting nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The degree of correction possible will depend on individual factors and the severity of the vision problem.

5. Is PRK a painful procedure?

Before the surgery, your eye will be numbed with eye drops to minimize any discomfort. During the procedure, you may feel pressure or mild discomfort, but it should not be painful. Following PRK, some patients may experience mild to moderate discomfort during the initial healing period.

6. What is the recovery process like?

After PRK, it takes time for the surface of the cornea to heal. You may experience blurry vision, sensitivity to light, and mild discomfort for a few days to a couple of weeks. It’s important to follow post-operative instructions, including using prescribed eye drops and avoiding activities that can potentially impact the healing process.

7. Are there any risks or complications associated with PRK?

As with any surgical procedure, PRK carries some risks. Potential complications include infection, dry eyes, glare, halos, and overcorrection or under-correction of vision. It’s essential to discuss these risks with your eye care professional to make an informed decision.

8. How long does it take to see the full results of PRK?

While vision improvement is typically noticeable within a few days after a PRK surgery near you, it may take several weeks or even months for your vision to stabilize and reach its full potential.

Remember, it’s important to consult with an experienced eye surgeon to address your specific concerns and determine if this is the right option for you.


PRK is a widely used eye surgery in Calgary that offers effective vision correction for individuals with nearsightedness, farsightedness, and astigmatism. By reshaping the cornea, this procedure can help improve your vision and reduce your reliance on glasses or contact lenses.
