LASIK and PRK are two of the most trusted laser eye surgeries available today. Both can correct blurry vision, reduce or eliminate the need for glasses and contacts, and offer long-term results, but theyโre not interchangeable.
If you live in San Jose or the surrounding area and you’re thinking about vision correction, understanding the difference between LASIK and PRK is the first step in choosing the procedure that fits your eyes, your lifestyle, and your long-term goals.
At Furlong Vision, weโve helped thousands of patients, ranging from tech professionals in their 30s to adults over 50 ready to ditch readers and make the right decision with confidence. Hereโs what you need to know before choosing your path to clearer vision.
Understanding LASIK and PRK: The Basics
Laser vision correction isnโt new, but the technologies behind it have evolved. LASIK and PRK are two FDA-approved procedures that use laser technology to reshape the cornea and correct common refractive errors like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
Both offer excellent long-term vision results. The key differences come down to how the procedure is performed, who qualifies, and how the eye heals afterward.
What Is LASIK?
LASIK (Laser-Assisted In Situ Keratomileusis) involves creating a thin flap on the surface of the cornea. A laser is then used to reshape the corneal tissue underneath, correcting how light enters the eye.
- Fast recovery: Most patients see improved vision within 24โ48 hours
- Minimal discomfort: Numbing drops are used; the procedure takes minutes
- High satisfaction: According to the American Refractive Surgery Council, LASIK has a patient satisfaction rate of over 96%, one of the highest in all of medicine
What Is PRK?
PRK (Photorefractive Keratectomy) is the original laser vision correction procedure, and itโs still widely used today for patients who arenโt ideal LASIK candidates.
Instead of creating a corneal flap, PRK works by gently removing the outer layer of the cornea before reshaping the tissue with a laser. The surface then heals naturally over several days.
- Great for thin corneas: Ideal for patients who arenโt eligible for LASIK
- Longer healing period: Recovery takes a bit more time, but vision outcomes are comparable to LASIK
- No flap = less risk: Especially beneficial for patients with active or high-impact lifestyles
Shared Benefits of Both Surgeries
Whether you choose LASIK or PRK, you can expect:
- Precise, customized correction of nearsightedness, farsightedness, or astigmatism
- Freedom from glasses or contacts in most daily activities
- A safe, well-studied procedure backed by decades of clinical success
With the right surgeon and a thorough evaluation, both LASIK and PRK deliver life-changing results, often in less time than it takes to get a new pair of glasses.
LASIK vs. PRK: Key Differences
While LASIK and PRK both use advanced laser technology to correct vision, the way each procedure is performed (and how the eye heals afterward) can make one a better fit for your needs than the other.
Hereโs how they compare across the most important factors:
LASIK vs. PRK at a Glance
| Feature | LASIK | PRK |
| Procedure Type | Corneal flap + laser reshaping | Surface layer removal + laser reshaping |
| Ideal For | Patients with healthy corneal thickness | Patients with thin corneas or corneal irregularities |
| Recovery Time | 1โ2 days for most daily activities | 3โ5 days off work; 1โ2 weeks for full recovery |
| Initial Discomfort | Minimal | Moderate (can include tearing, light sensitivity) |
| Vision Results | Clear vision typically within 24โ48 hours | Clear vision develops more gradually |
| Risk of Dry Eye | Slightly higher due to flap creation | Lower, flapless approach preserves more corneal nerves |
| Corneal Strength After | Slightly reduced due to flap | Preserves more natural strength of the eye |
| Flap Complications | Rare, but possible (flap-related risks) | None (no flap involved) |
Both LASIK and PRK offer long-term vision correction, and outcomes are very similar over time. The biggest differences are in recovery experience, corneal anatomy requirements, and personal lifestyle factors.
Factors That Help Determine the Right Procedure
Thereโs no one โbestโ laser eye surgery. Only the one that fits your eyes, your lifestyle, and your vision goals. Here are the key factors that help determine whether LASIK or PRK is the right choice for you.
Corneal Thickness and Eye Anatomy
One of the first things your surgeon will assess is the thickness and shape of your cornea. LASIK requires enough tissue to safely create a corneal flap. If your corneas are thinner than average or if youโve had previous eye injuries or surgeries, PRK may be the safer, more effective option.
Good to know: A detailed corneal mapping exam at Furlong Vision will help determine this in your consultation.
Lifestyle, Work, and Hobbies
Certain lifestyles put more pressure on your eyes. If you play contact sports, work in a physically demanding environment, or are at higher risk for eye injuries, PRK may be preferred. Since thereโs no flap involved, thereโs no risk of it shifting due to impact.
On the other hand, if you want fast visual recovery and have a lower-risk lifestyle, LASIK may be the better match.
Age and Long-Term Vision Planning
As you enter your 40s and 50s, your eyes naturally begin to change; most people start experiencing presbyopia, or age-related near vision loss. Your surgeon may take this into account when recommending LASIK or PRK and may also discuss options like monovision correction.
While both LASIK and PRK are effective for older adults, the long-term planning strategy may differ slightly depending on your age, vision goals, and whether youโve already had other corrective procedures.
Digital Eye Strain in Younger Adults
If youโre in your 20s or 30s and spend most of your day in front of a screen, youโre not alone. A 2023 study from the Vision Council found that 68% of adults report symptoms of digital eye strain; a growing reason why many younger professionals are turning to LASIK or PRK for long-term relief from glasses or contacts

Both LASIK and PRK can offer long-term freedom, but the right procedure depends on your eye health, daily habits, and future plans.

Frequently Asked Questions About LASIK and PRK
Have more questions? We have more answers.
Is LASIK better than PRK?
Not necessarily. Both procedures offer excellent results. LASIK tends to have faster recovery and less discomfort, while PRK is ideal for patients with thin corneas or those in high-impact professions.ย
The best procedure depends on your eye anatomy, health history, and lifestyle.
How do I know if Iโm a candidate for LASIK or PRK?
The only way to know for sure is through a professional eye exam and consultation. At Furlong Vision in San Jose, we use detailed corneal mapping and diagnostic imaging to determine which procedure, LASIK or PRK, is the safest and most effective for your eyes.
What is the recovery time difference between LASIK and PRK?
LASIK patients typically return to work or daily activities within 24 to 48 hours. PRK requires a longer recovery, about 3 to 5 days off work, with full visual clarity improving over 1โ2 weeks.
Is PRK more painful than LASIK?
PRK can involve more initial discomfort during the healing phase, including light sensitivity and tearing. However, this is temporary and manageable with medication. LASIK usually involves minimal discomfort due to the flap-based technique.
How long do the results of LASIK and PRK last?
Both procedures are designed to offer permanent vision correction, although natural age-related changes, like presbyopia, can still occur over time. Many patients enjoy decades of clearer vision without glasses or contacts.
Can I have LASIK or PRK if I have dry eyes?
Possibly. Patients with chronic dry eye may be better suited for PRK, which tends to reduce the risk of worsening dryness. During your consultation, our team will evaluate your tear film and eye surface health to make the safest recommendation.
