Points clés

PRK (Photorefractive Keratectomy) is a laser vision correction procedure that utilizes an excimer laser to precisely reshape the cornea and correct refractive errors.
PRK is performed on the surface of the cornea, during which the surgeon brushes off the outermost layer of cells before using the excimer laser to correct a patient’s refractive error.
PRK is often recommended for patients with thin, steep, or irregular shaped corneas to correct nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
The recovery is slightly longer than other vision correction procedures (SMILE and LASIK); however, the results are comparable to SMILE or LASIK, with most patients achieving 20/20 vision or better.
Herzig Eye Institute conducts free consultations for patients considering laser vision correction in both Toronto and Ottawa. During the consultation, patients will undergo a comprehensive eye exam with an eye doctor, including advanced diagnostic testing, to determine their candidacy for laser vision correction. If you are not a suitable candidate for PRK, Herzig Eye Institute offers alternatives like SMILE, LASIK, and the Intraocular Collamer Lens (ICL) to ensure the best and safest possible visual outcome.

What is PRK?

PRK, or Photorefractive Keratectomy, is the first generation of laser vision correction technology. Since 1989, millions of people have had their vision corrected with PRK. Commonly referred to as ‘surface ablation’, PRK uses an excimer laser to reshape the cornea and correct nearsightedness, farsightedness, and astigmatism.

PRK is recommended when the surgeon determines it is the only safe option, particularly for patients with corneal abnormalities.

Custom PRK Candidacy & Treatments

Lors de votre consultation gratuite, vous subirez des tests diagnostiques pour déterminer votre candidature à la correction de la vision au laser. Pour comprendre quelle procédure vous convient, vous rencontrerez l’un de nos consultants en réfraction expérimentés pour discuter de vos objectifs visuels, poser toutes vos questions, partager les résultats de vos diagnostics et de vos examens oculaires, prendre rendez-vous pour la date de votre intervention et discuter des instructions préopératoires.

PRK may be the preferred laser vision correction procedure:

When a pre-existing problem is present on the cornea, like thin, steep, or irregularly shaped corneas, and results in better vision than with SMILE® or Custom LASIK.
When there is a structural abnormality in the cornea, making Custom LASIK or SMILE® unsafe.

If your consultation reveals you are not a candidate for PRK, we are pleased to offer other refractive procedures, including SMILE® and Custom LASIK, as well as intraocular procedures: Refractive Lens Exchange (RLE) and Intraocular Collamer Lens (ICL).

Préparation à la procédure
À quoi s’attendre pendant la procédure
À quoi s’attendre après la procédure
Examens postopératoires

Pour préparer votre procédure, il peut y avoir quelques considérations préopératoires. Tout cela vous sera communiqué par votre consultant en réfraction et le médecin lors de votre consultation complète. Certaines de ces instructions pourraient inclure :

Passer à des lunettes et éviter de porter des lentilles de contact pendant 1 à 8 semaines (selon le type de verres que vous portez)
Organiser un transport vers et depuis Herzig Eye Institute pour votre journée de procédure

The PRK procedure is done one eye at a time, while the other eye is covered. To stop you from blinking, your surgeon will use a lid speculum and apply topical anesthetic numbing drops to prevent any pain. Once the epithelium is gently removed, the excimer laser will be used to reshape your cornea. The laser will track and adjust to any eye movement.

Une fois terminé, une lentille de contact à bandage souple est placée sur l’œil pour le protéger et favoriser la guérison. Le processus est ensuite répété sur l’autre œil.

Directly following the procedure, you will be examined and given your first set of drops. After your examination, it is recommended you go home and rest as you may experience sensitivity. Discomfort is normal during this time. The drops and medications provided will help minimize this discomfort.

A medicated drop regimen needs to be followed after the procedure. For four to five days after the procedure, the protective contact lens bandage must remain on to help promote the healing of the epithelium. While the healing time is longer for PRK, your vision will continue to improve and stabilize in the days and weeks following your procedure.

D’autres instructions seront fournies par votre consultant réfractif, les infirmières et le chirurgien le jour de votre procédure.

It is critical you are seen for all necessary post-operative follow up appointments at Herzig Eye Institute or with your referring optometrist. The typical post-operative follow ups are: 1 day, 4-5 days, 1 month, and 3 months after your procedure. Additional appointments may be recommended.

Frequently Asked Questions (Custom PRK)

PRK reshapes the cornea without creating a flap, making it a good option for patients with thinner corneas, dry eyes, or those involved in contact sports or certain occupations. LASIK involves creating a corneal flap, which allows for faster initial recovery.

Vision improves gradually over the first few days, though full healing may take several weeks. Most patients return to normal routines in about a week, with full stabilization taking several weeks.

Mild discomfort, dryness, or light sensitivity is common during the first few days. These symptoms are well managed with drops, lubricating tears, and medications provided by your surgeon at Herzig Eye Institute.

Yes. PRK has been performed safely for more than 30 years and has a long history of strong outcomes. It is often recommended to patients who may not be suitable candidates for LASIK.
