A detailed comparison of two popular procedures for clearer vision.
For millions of people, glasses and contact lenses are a daily necessity. While they help correct vision, many patients dream of waking up with clear sight and no need for corrective lenses. Vision correction surgery makes these goals possible, with LASIK and PRK being the two most widely performed procedures.
At Anaheim Eye, we’ve guided countless patients through the decision-making process between LASIK and PRK. Both surgeries reshape the cornea to improve how light focuses on the retina, correcting nearsightedness, farsightedness, and astigmatism. Yet, the methods and recovery experiences differ, which can make one option better suited for a particular patient than the other.
This article will walk you through how each procedure works, their advantages and disadvantages, recovery expectations, and which patients are the best candidates for them.
“Both LASIK and PRK can give you freedom from glasses — the difference lies in how they get you there.”
How LASIK Works
LASIK (Laser-Assisted in Situ Keratomileusis) is the most common type of vision correction surgery worldwide. The procedure involves creating a thin flap on the surface of the cornea. A laser then reshapes the underlying corneal tissue to correct refractive errors, after which the flap is gently repositioned.
Because the flap acts as a natural bandage, healing is usually quick and relatively comfortable. Most LASIK patients notice significant improvements in vision within 24–48 hours.
How PRK Works
PRK (Photorefractive Keratectomy), on the other hand, does not involve creating a flap. Instead, the outer layer of the cornea (the epithelium) is gently removed before the laser reshapes the cornea underneath. The epithelium grows back naturally during the healing process, which can take several days.
PRK was actually the first laser vision correction technique developed, and while LASIK became more popular because of its faster recovery, PRK remains an excellent option, especially for patients who may not be good LASIK candidates.
Benefits of LASIK
Patients often choose LASIK for its convenience and quick results.
-
Fast recovery: Most people see improved vision within a day or two.
-
Minimal discomfort: The flap reduces surface healing, leading to less pain post-surgery.
-
Predictable outcomes: High success rates and reliable vision correction.
-
Return to daily life quickly: Many patients go back to work within 48 hours.
LASIK is often appealing to busy professionals, students, or anyone who wants to minimize downtime.
Benefits of PRK
PRK may not be as fast, but it offers advantages of its own:
-
No flap required: Ideal for patients with thin corneas, which makes LASIK riskier.
-
Stronger corneal structure long-term: Because no flap is created, PRK may be better for patients at risk of trauma (such as athletes or military personnel).
-
Excellent results: Once healing is complete, PRK provides the same level of vision correction as LASIK.
For patients willing to go through a slightly longer recovery, PRK is a safe, effective alternative with results that last just as long.
Recovery Differences
The biggest difference between LASIK and PRK lies in the recovery experience.
-
LASIK recovery: Quick, with most patients noticing sharp vision in 1–2 days. Temporary side effects may include dryness, glare, or halos at night.
-
PRK recovery: Slower, with vision gradually improving over 1–2 weeks as the corneal surface heals. Patients may experience more discomfort in the first few days, and complete stabilization can take a month or longer.
While LASIK provides faster gratification, PRK offers comparable results — just on a different timeline.
Risks and Considerations
Both LASIK and PRK are considered very safe, but like any surgery, they carry potential risks:
-
Dry eye: More common after LASIK, though usually temporary.
-
Glare or halos: Both procedures can cause nighttime visual disturbances, especially in the first few months.
-
Regression: Rarely, vision may change slightly over time, requiring enhancement surgery.
-
Infection or complications: Extremely rare but possible.
“Choosing between LASIK and PRK isn’t about which surgery is better overall — it’s about which one is better for you.”
Who Makes the Best Candidate for Each?
-
Ideal LASIK candidates: Patients with thick corneas, stable prescriptions, and no history of eye disease. They want quick recovery and minimal downtime.
-
Ideal PRK candidates: Patients with thin corneas, irregular corneal shapes, or those in professions where eye trauma risk is higher. Also suitable for patients who cannot undergo LASIK due to flap-related concerns.
At Anaheim Eye, we perform comprehensive evaluations to determine corneal thickness, eye health, and lifestyle needs before recommending one procedure over the other.
FAQs About LASIK vs. PRK
Is LASIK always the better option because it’s faster?
Not necessarily. While LASIK offers faster recovery, PRK may be safer for certain patients, such as those with thin corneas or active lifestyles.
Will I need glasses again after LASIK or PRK?
Most patients enjoy clear vision for years, though some may need reading glasses later in life due to natural aging changes (presbyopia).
Is PRK more painful than LASIK?
PRK can cause more discomfort during the first few days as the surface heals. However, pain is manageable with medications, and long-term results are just as beneficial.
Are the results permanent?
Yes, the changes to the cornea are permanent. However, normal age-related changes in the eyes may still occur.
The Anaheim Eye Approach
What sets Anaheim Eye apart is the emphasis on personalized treatment planning. Our team doesn’t just recommend LASIK or PRK based on popularity. We take into account your eye anatomy, lifestyle, career demands, and personal preferences. By tailoring recommendations to each patient, we ensure safe procedures and excellent results that truly fit your life.
“Our goal isn’t just to give you clear vision — it’s to give you the freedom to live life on your terms.”
Conclusion
Both LASIK and PRK offer life-changing results for people tired of glasses or contacts. While LASIK is known for its quick recovery, PRK remains a strong choice for patients who value long-term corneal health or are not LASIK candidates. The key is not which surgery is “better,” but which one is right for you.
At Anaheim Eye, our team provides expert evaluations and honest guidance to help you choose the safest, most effective vision correction procedure. Call today to schedule your consultation and discover whether LASIK or PRK is the perfect fit for your lifestyle.
