If you’re considering laser eye surgery to reduce or eliminate your dependency on glasses or contact lenses, you’re not alone. Thousands of Canadians choose refractive surgery each year to improve their vision and quality of life. Two of the most well-known procedures are LASIK and PRK. While both are highly effective and safe, they have key differences that may make one a better fit for your needs.
At Valley Laser Eye Centre, we specialize in advanced vision correction procedures and patient education. In this article, we’ll help you understand the differences between LASIK and PRK so you can make an informed decision. We’ll compare the procedures, benefits, risks, recovery times, and more, all backed by the expertise of Dr. John F. Blaylock and our experienced team.
Understanding Laser Eye Surgery
Laser eye surgery involves reshaping the cornea, which is the transparent front part of your eye. The goal is to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. These conditions are caused by irregularities in how the eye focuses light onto the retina. By using laser technology to reshape the cornea, light can be correctly focused, leading to clearer vision.
Both LASIK and PRK use an excimer laser to reshape the cornea, but the process for accessing the corneal tissue differs between the two. This difference affects recovery time, post-operative care, and suitability for certain patients.
What is LASIK?
LASIK, short for Laser-Assisted in Situ Keratomileusis, is currently the most popular form of laser vision correction. It is known for its precision and relatively quick recovery. During LASIK, a femtosecond laser creates a thin flap in the outer layer of the cornea. The flap is gently lifted, and the excimer laser is used to reshape the cornea beneath it. Once the reshaping is complete, the flap is repositioned and begins healing naturally.
The procedure itself typically takes only 10 to 15 minutes for both eyes. Most patients report little to no discomfort during the surgery, and many begin to see improved vision within 24 hours. Learn more about LASIK here.
What is PRK?
PRK, or Photorefractive Keratectomy, was the first type of laser vision correction procedure developed and is still widely used today. Instead of creating a flap, the surgeon removes the thin outer layer of the cornea, called the epithelium. The laser is then applied directly to the surface of the cornea to reshape it.
After surgery, the epithelium regenerates over the course of several days. This method can result in more discomfort during the initial recovery period, but it also eliminates the possibility of flap-related complications. Read more about PRK at Valley Laser Eye Centre.
LASIK vs. PRK: Side-by-Side Comparison
To help simplify the differences, here is a table that compares LASIK and PRK across key aspects:
| Feature | LASIK | PRK |
| How it’s done | Corneal flap created and lifted | Surface epithelium removed |
| Procedure time | ~10 minutes per eye | ~10 minutes per eye |
| Discomfort | Mild, temporary dryness | Moderate to high for 2 to 3 days |
| Recovery time | 1 to 2 days for functional vision | 5 to 7 days for functional vision |
| Long-term results | Excellent | Excellent |
| Risk of flap issues | Possible | None |
| Ideal candidates | Normal corneal thickness, quick recovery needed | Thin corneas, dry eyes, contact sports |
| Vision clarity timeline | Rapid improvement within 24–48 hours | Gradual improvement over 1 to 2 weeks |
Am I a Candidate for LASIK or PRK?
Determining which surgery is right for you depends on a number of factors, including the health of your eyes, the thickness of your cornea, and your lifestyle. At Valley Laser Eye Centre, we use comprehensive diagnostic imaging to assess these variables and recommend the best option for your unique needs.
You may be a good candidate for LASIK if:
- Your cornea is thick enough to support the creation of a flap
- You have a stable prescription
- You do not have chronic dry eye
- You are looking for a fast recovery and minimal downtime
You may be better suited to PRK if:
- You have a thinner cornea that makes flap creation risky
- You have a physically active lifestyle or participate in contact sports
- You’ve previously had eye surgery or trauma
- You’re concerned about flap-related complications

What Does Recovery Look Like?
LASIK recovery is known for being fast and relatively comfortable. Most patients return to work or regular activities within 1 to 2 days. Some people experience dryness, glare, or halos around lights, especially at night, but these symptoms usually improve within a few weeks.
PRK recovery takes longer because the surface cells of the cornea must regenerate. Functional vision returns in about 5 to 7 days, but it can take several weeks for vision to fully stabilize. Discomfort is more pronounced during the first 48 to 72 hours, and patients typically use bandage contact lenses and medicated eye drops to assist healing.
At VLEC, we provide detailed recovery instructions and follow-up care to ensure optimal healing, regardless of the procedure you choose.
What Results Can I Expect?
Both LASIK and PRK offer excellent long-term vision outcomes. Studies show that the vast majority of patients achieve 20/20 vision or better, and many are able to stop wearing corrective lenses altogether.
The final visual result depends on several factors, including the skill of your surgeon, the type of laser used, and how closely you follow post-operative care instructions. At Valley Laser Eye Centre, our use of advanced technology and customized treatment planning helps us deliver consistently outstanding outcomes.

What Are the Risks and Side Effects?
All surgeries come with potential risks. However, LASIK and PRK are among the safest elective procedures available today. The complication rate is very low, especially when performed by experienced surgeons using modern technology.
Possible side effects of LASIK include:
- Temporary dry eye
- Flap complications (rare but possible)
- Glare, halos, or night vision issues
PRK may involve:
- Greater initial discomfort
- Slower recovery
- Risk of corneal haze (rare with today’s protocols)
Our pre-operative screening is designed to reduce your risk by identifying any factors that could affect the success of the procedure. Read more on how we keep you safe.
How Much Does It Cost?
Laser eye surgery is an investment in your long-term visual freedom. While the upfront cost may seem significant, many patients find it saves them money over time compared to the recurring expenses of glasses and contact lenses.
Costs can vary based on the procedure and technology used. In general, PRK may be slightly less expensive than LASIK because it involves fewer surgical steps. Neither procedure is typically covered by MSP, but many private insurance plans may provide partial coverage. We also offer financing options to make surgery accessible.
