LASIK vs. PRK: What’s the Difference?
Understanding Two Popular Vision Correction Procedures.
If you’re considering laser vision correction, you’ve probably come across two common procedures: LASIK and PRK. Both procedures are designed to reduce or eliminate the need for glasses or contact lenses by correcting common refractive errors like nearsightedness, farsightedness, and astigmatism.
While LASIK is often the more familiar name, PRK remains an excellent option for many patients. The best procedure depends on your unique eyes, lifestyle, and vision goals.
At Infocus Eye Care, we believe that understanding your options is the first step toward making an informed decision.
What is LASIK?
LASIK (Laser-Assisted In Situ Keratomileusis) is one of the most commonly performed vision correction procedures.
During LASIK, a thin flap is created on the surface of the cornea. An excimer laser is then used to reshape the underlying corneal tissue before the flap is carefully repositioned.
Benefits of LASIK include:
Rapid visual recovery
Minimal discomfort after surgery
Most patients return to normal activities within a day or two
Excellent long-term vision outcomes for appropriate candidates
Many patients notice significantly improved vision within 24 hours.
What is PRK?
PRK (Photorefractive Keratectomy), was the first type of laser vision correction and is still widely performed today.
Instead of creating a corneal flap, the thin outer layer of the cornea (the epithelium) is gently removed before the laser reshapes the cornea. This layer naturally regenerates over the following several days.
Benefits of PRK include:
No corneal flap
Possible option for patients with thinner corneas
May be recommended for individuals with certain occupations or active lifestyles
Long-term visual outcomes comparable to LASIK
Although recovery takes a little longer than LASIK, patients achieve equally excellent vision once healing is complete.
How are LASIK and PRK Different?
While both procedures use the same laser technology to reshape the cornea, the primary difference is how the surgeon accesses the treatment area.
PRK
No corneal flap
Slower recovery over several days
Mild discomfort during the first few days of healing
Often recommended for thinner corneas or certain lifestyles
LASIK
Creates a thin corneal flap
Faster visual recovery
Usually less discomfort immediately after surgery
Ideal for many patients
Both procedures have excellent success rates when patients are carefully evaluated beforehand.
Which Procedure is Right for You?
The answer depends on several factors, including:
Your eyeglass prescription
Corneal thickness and shape
Overall eye health
Lifestyle and hobbies
Occupation
Personal preferences
Not everyone is a candidate for LASIK, but many patients who aren’t ideal LASIK candidates may still be excellent candidates for PRK.
A comprehensive evaluation allows your surgeon to recommend the safest and most effective option for your individual eyes.
What About Recovery?
LASIK Recovery
Most patients notice improved vision within one day and can return to many normal activities quickly.
PRK Recovery
Vision improves more gradually over several days to weeks as the surface of the cornea heals. During this time, patients may experience temporary blurry vision and mild discomfort.
Although PRK requires a little more patience during recovery, the long-term visual results are comparable to LASIK.
The Importance of a Comprehensive Evaluation
Choosing between LASIK and PRK isn’t about selecting the “better” procedure— it’s about choosing the procedure that’s best for your eyes.
During your consultation, your provider and the clinical team will perform detailed measurements of your eyes, discuss your vision goals, review your medical history, and determine whether laser vision correction is right for you.
