Many people exploring vision correction find themselves deciding between LASIK and PRK. Both procedures are highly effective, widely trusted, and capable of producing excellent long-term vision results. But they’re not identical, and understanding how they differ can help you feel confident about choosing the option that best fits your eyes and your lifestyle.
At the Bochner Eye Institute in Toronto, Dr. Raymond Stein has performed vision correction for patients from across Canada and around the world. For more than 95 years, Bochner has remained the region’s leading center for advanced eye care and surgical innovation, and Dr. Stein is known as a foremost eye surgeon in our area and beyond.
How LASIK Works
LASIK is one of the most widely performed laser vision correction procedures because it combines precision, comfort, and rapid recovery. During the procedure, Dr. Stein creates a very thin flap on the cornea, the transparent front window of the eye. He carefully lifts this flap to expose the underlying corneal tissue.
A computer-guided excimer laser reshapes the cornea with remarkable accuracy. It corrects nearsightedness, farsightedness, and astigmatism by improving how light focuses on the retina. Once the corneal shape has been refined, Dr. Stein gently replaces the flap, which will close naturally without stitches.
This flap acts as a natural bandage, enabling fast recovery. Many patients notice clearer vision within hours, and vision typically continues to sharpen over the next day or two.
Key advantages of LASIK include:
• Very fast visual recovery
• Minimal procedure-related discomfort
• Most patients return to work or daily routines within a day or two
• Excellent long-term clarity for appropriately selected candidates
LASIK is often recommended for individuals with healthy corneal thickness, stable prescriptions, and corneas free of significant surface irregularities.
How PRK Works
PRK (photorefractive keratectomy) was the original form of laser vision correction and remains an excellent treatment option today.
Instead of creating a corneal flap, PRK involves the removal of the surface layer of the cornea. Then, Dr. Stein uses the same precise laser cornea reshaping as LASIK. The surface layer naturally regenerates during the early healing period.
PRK advantages include:
- Ideal for patients with thinner corneas
- Strong option for those with mild irregularities on the corneal surface, including dry eye
- No corneal flap involved, which can be preferable for patients with active lifestyles or certain occupational demands
Although PRK has a longer healing timeline compared to LASIK, the visual results between the two procedures are ultimately very similar.
Which Procedure Is Better?
Neither procedure is universally “better” — it’s all about which is better for you. Ultimately, the right choice depends on your eye health and lifestyle needs.
Dr. Stein performs a detailed examination to determine which option offers the safest and most predictable outcome for your vision.
