LASIK in Ontario: Advanced Vision Correction with Expert Care
- LASIK (Laser-Assisted In Situ Keratomileusis) reshapes the cornea using a precise laser to correct common refractive errors such as nearsightedness, farsightedness, and astigmatism. A thin flap is created on the cornea’s surface, allowing for quick recovery and exceptional results.
- PRK (Photorefractive Keratectomy) is an alternative for individuals with thin corneas. Instead of creating a flap, the outer layer of the cornea is removed before reshaping, making it ideal for patients who are not candidates for LASIK.
- Contoura LASIK provides a highly personalized approach to vision correction. By using advanced mapping technology, this procedure delivers precise treatment, correcting a wider range of visual imperfections and reducing potential complications, even for individuals with unique corneal conditions.

PRK Surgery (Photorefractive Keratectomy)
What is PRK Surgery?
PRK Surgery (Photorefractive Keratectomy) is a type of laser eye surgery that is used to correct refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. PRK is an alternative to LASIK eye surgery and is particularly suitable for individuals who may not be candidates for LASIK due to certain corneal characteristics.
Overview of the PRK surgery process:
- Corneal Epithelium Removal:
- In PRK, the surgeon begins by removing the thin outer layer of the cornea called the epithelium. This can be done using an alcohol solution, a special brush, or a laser.
- Laser Reshaping of the Cornea:
- Once the epithelium is removed, a laser is used to precisely reshape the cornea. The laser ablates or removes microscopic amounts of corneal tissue based on the patient’s refractive error. The goal is to correct the curvature of the cornea and improve the focus of light on the retina.
- Healing Process:
- Unlike LASIK, where a corneal flap is created, PRK does not involve creating a flap. Instead, the corneal surface is allowed to regenerate naturally. The healing process involves the growth of new epithelial cells over the treated area.
- Post-operative Care:
- Following PRK surgery, patients are given medicated eye drops to aid in the healing process and prevent infection. Recovery may take a bit longer compared to LASIK, and patients may experience temporary discomfort during the initial days.
Key considerations for PRK surgery include:
- Corneal Thickness: PRK may be a suitable option for individuals with thinner corneas who may not be ideal candidates for LASIK.
- Occupational Considerations: PRK may be recommended for individuals with occupations or lifestyles that carry a risk of corneal injury, as it eliminates the creation of a corneal flap.
- Healing Time: The initial visual recovery may take longer with PRK compared to LASIK. Patients typically experience optimal vision several weeks after the procedure.
PRK is a well-established and effective procedure for vision correction, and its suitability depends on individual factors. It’s important to consult with an experienced refractive surgeon or eye care professional to determine the most appropriate laser eye surgery option based on your eye health and lifestyle.
Corneal Collagen Crosslinking (CXL)
Keratoconus is a progressive disease of the cornea. With collagen cross-linking (CXL), you can halt the progression of keratoconus by strengthening your cornea.
Refractive Lens Exchange (RLE)
Refractive lens exchange (RLE), is when a clear lens is implanted to replace your eye’s natural lens to correct your vision.
This procedure is often used for pre-cataract patients, as a preventative vision correction solution. Refractive lens exchange (RLE) can also correct nearsightedness, farsightedness, and astigmatism.
Dry Eye Treatment
Dry eye is an irritating, painful, and common condition in which the eye fails to properly produce quality tears. When left untreated, it may lead to ulcers and scars on the cornea.
Depending on the severity of your condition, there are a variety of treatments to relieve dry eyes.
Lifestyle Lenses
Lifestyle lenses are a premium lens option that offers a more functional range of vision, and are designed to reduce the need for distance and reading glasses.
We offer the latest and most advanced lifestyle lens on the market.
Intacs® Corneal Implants for Keratoconus
The surgical implantation of intracorneal ring segments or Intacs® is a minimally invasive surgical option to improve the corneal shape in patients with keratoconus.
Intacs® are surgically inserted into a thin channel created by a femtosecond laser in the periphery of the cornea. Intacs® is also known as surgical implantation of intracorneal ring segments.
Pterygium Surgery
Pterygium surgery is performed under topical anesthesia on an outpatient basis.
Monovision LASIK
Monovision lasik can treat presbyopia. One eye would remain slightly nearsighted while correcting your other eye for distance vision. With both eyes open, you’ll experience clear and comfortable vision both near and far.
