An introduction to Custom PRK

  • Surgeons use PRK to correct your vision so you can enjoy freedom from contact lenses and glasses.

  • Photorefractive keratectomy (PRK) is the original laser eye surgery.

  • In certain cases, we use PRK to treat nearsightedness, farsightedness and astigmatism.

  • PRK delivers particularly outstanding results for those who are nearsighted.

  • Most patients have 20/20 vision or better a year after the procedure.

How do you know if Custom PRK is right for you?

Many people ask “what the difference is between PRK surgery and LASIK eye surgery?”

The difference is that we perform Custom PRK on the top surface of the cornea after removing or lifting the corneal epithelium rather than the corneal flap. Custom PRK is the right procedure for people with large pupils, or thin or structurally unique corneas, and for individuals involved in contact sports.

Therefore, if you are not a candidate for LASIK or SMILE, you may want to consider Custom PRK surgery instead. These procedures deliver the same result.

It’s difficult to find helpful and straight forward information online about PRK. Our goal is to myth bust and help you find the right laser eye treatment for you (even if it’s not at our clinic).

How PRK surgery works

The surgeon uses the laser to sculpt the surface of the cornea. That results in a clearer vision than before. We perform the Custom PRK surgery in-office. It only takes about 15 minutes.

We will give you numbing eye drops and then we direct an excimer laser over your eyes which reshapes your corneas by removing microscopic amounts of tissue via pulses of ultraviolet light1. Custom PRK is a pain-free procedure. Most patients don’t feel anything except for a little bit of pressure.

We take 5 minutes to treat each eye. Then we place a bandage contact lens on your eye to protect it. We carefully remove this bandage contact lens in a few days as your eye heals.

We use the most accurate eye laser in the world, according to US FDA trials

We use the ZEISS MEL® 90 excimer laser when doing PRK for our patients.

This excimer laser offers incredibly accurate, auto-stabilized calibrated laser energy delivery. ZEISS was the first laser manufacturer to produce closed-loop energy stabilization – the patented method of energy stabilization used by the MEL 90.

Closed-loop energy stabilization gives this laser the fastest response time of any laser, without the need for frequent user calibration.

According to rigorous US FDA trials, the ZEISS MEL 90 is proven to be the most accurate eye laser in the world.

Clearview Institute, Home to the Most Advanced PRK Technology in North America

Clearview Institute is home to the most advanced PRK technology available in North America. ZEISS has the most advanced platform in general for laser vision correction with well-proven topography.

Regarding PRK; our procedure of choice is Epi-Bowman’s Keratectomy (EBK) and is done using the Epi-Clear, which precisely strips the epithelium layer while leaving the basal layer and Bowman’s membrane completely intact. Because of this, it offers 30% faster healing.

Clearview Institute, a fully accredited and licensed eye surgery center, is also home to the some of the top laser eye surgeons in North America, including Dr. Kranemann, who is board certified in not only Canada but also the United States.

We understand that many patients can feel a bit nervous prior to receiving any new treatment, but our knowledgeable and friendly staff deliver excellent care, going out of their way to accommodate you and to answer any and all questions every step of the way.

For example, we recently had a diabetic patient come in who felt a bit under the weather as they hadn’t eaten in a while. Our staff were going on a Tim Horton’s run and brought the patient a snack, unasked. This is a common occurrence at Clearview Institute because we care about our patients as people first, conditions second.

You will feel at peace knowing that you are receiving the best possible vision care. In combination with the most advanced vision correction laser and state-of-the-art procedure suites with ergonomic chairs designed for your comfort, the level of care that we offer is unparalleled.
