When evaluating LASIK vs PRK, most patients find that both procedures can effectively reduce dependence on glasses or contact lenses, yet each works differently and suits a different range of candidates. At Eastside Eye Physicians, our board-certified ophthalmologists have served the Detroit metropolitan community since 1955, and we understand that choosing a refractive procedure is a significant decision. This page offers a straightforward, medically accurate comparison so you can arrive at your consultation informed and confident.

What Is LASIK?
LASIK (Laser-Assisted In Situ Keratomileusis) is a widely performed refractive procedure in which a surgeon creates a thin flap in the outer layer of the cornea, lifts it, and uses an excimer laser to precisely reshape the underlying corneal tissue. The flap is then repositioned, where it adheres naturally without stitches.
What LASIK May Address
LASIK may help reduce or eliminate refractive errors including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism in appropriate candidates. The procedure is FDA-approved for the correction of refractive errors within specific ranges as determined by preoperative evaluation.
Typical Experience and Results
Most patients notice improved vision within 24 to 48 hours of the procedure. Minimal downtime is typical for most patients, and many return to routine activities quickly. Individual results vary, and outcomes depend on factors such as the degree of refractive error, corneal thickness, and overall eye health. A thorough preoperative evaluation determines whether LASIK is an appropriate option. Learn more about LASIK and PRK surgery at Eastside Eye Physicians.
What Is PRK?
PRK (Photorefractive Keratectomy) is the predecessor to LASIK and remains a well-established refractive procedure. Rather than creating a corneal flap, the surgeon gently removes the thin outer layer of the cornea, called the epithelium, and then applies the excimer laser directly to the corneal surface to reshape it. The epithelium regenerates naturally over the following days.
What PRK May Address
Like LASIK, PRK may help reduce dependence on corrective lenses for patients with myopia, hyperopia, and astigmatism, within qualifying ranges. Because no flap is created, PRK preserves more of the corneal structure, which may make it preferable for certain patients.
Typical Experience and Results
Visual recovery with PRK is more gradual than with LASIK, typically taking one to three weeks as the epithelium heals. Some patients experience temporary discomfort during the initial healing period. However, long-term visual outcomes with PRK are comparable to LASIK for appropriate candidates. Individual results may vary based on each patient’s anatomy and healing response.
Key Differences Between LASIK and PRK
| Category | LASIK | PRK |
|---|---|---|
| How It Works | Corneal flap created; laser reshapes tissue beneath | Epithelium removed; laser applied directly to corneal surface |
| Treatment Areas | Myopia, hyperopia, astigmatism (within qualifying ranges) | Myopia, hyperopia, astigmatism (within qualifying ranges) |
| Results Timeline | Improved vision often noted within 24 to 48 hours | Gradual improvement over one to three weeks |
| Duration of Results | Long-lasting; individual results vary | Long-lasting; individual results vary |
| Recovery | Minimal downtime for most patients | Longer healing period; temporary discomfort possible |
| Ideal Candidate | Adequate corneal thickness; no significant dry eye | Thinner corneas; active lifestyle with contact-sport concerns; prior corneal issues |
The table above captures the most direct comparisons, but the decision between LASIK vs PRK often comes down to factors that numbers and categories cannot fully convey. Corneal thickness is one of the most important considerations: patients with thinner corneas may not have sufficient tissue to safely accommodate a flap, making PRK the more appropriate option. Patients with certain occupations or active lifestyles may also benefit from PRK’s flap-free approach, since there is no flap to be disrupted by contact or impact. Conversely, patients who prefer a faster initial recovery and have no contraindications to flap creation may find LASIK better aligned with their needs. Only a comprehensive preoperative evaluation can determine which procedure is appropriate.

Which Is Right for You?
Determining whether LASIK or PRK is the better fit requires an individualized evaluation, not a generalized checklist. That said, understanding common candidate profiles can help frame the conversation you will have with your surgeon.
Patients who tend to be strong LASIK candidates often have adequate corneal thickness, stable refractive prescriptions for at least one to two years, no significant history of dry eye disease, and no corneal irregularities. If you have been wearing glasses or contact lenses for years and have generally healthy eyes, LASIK may be a viable option worth exploring at consultation.
PRK may be recommended for patients with corneas that are too thin for safe flap creation, those with certain corneal surface irregularities, or patients whose profession or recreational activities involve a higher risk of eye contact or impact. PRK eliminates any concern related to flap stability and may be associated with a lower risk of certain flap-related complications over time.
Both procedures require that patients be at least 18 years of age, have stable vision, and be free of certain eye diseases. Patients managing conditions such as glaucoma or diabetic eye changes should discuss those factors specifically with their ophthalmologist. The team at Eastside Eye Physicians provides personalized recommendations based on your complete ocular history, corneal measurements, and lifestyle considerations.

Frequently Asked Questions: LASIK vs PRK
Is LASIK or PRK more affordable?
The cost of LASIK vs PRK varies depending on the technology used, the degree of correction required, and the specific fees of the surgical practice. In many cases, the procedures are priced comparably. Financing options may be available. Refractive surgery is generally not covered by standard vision insurance plans, though some medical plans may offer partial benefits in select circumstances. Reviewing your payment options at Eastside Eye Physicians is a helpful first step.
Can LASIK and PRK be combined with other eye procedures?
In some cases, refractive procedures may be performed in conjunction with other treatments, depending on a patient’s overall eye health and specific conditions. However, combining procedures is not appropriate for every patient and must be evaluated individually. Patients with cataracts, for example, may be better served by lens-based correction. A comprehensive evaluation will help determine which approach, or combination of approaches, is clinically appropriate for your situation.
How does recovery compare between LASIK and PRK?
Recovery timelines differ meaningfully between the two procedures. With LASIK, most patients notice improved vision within one to two days and experience minimal downtime. With PRK, the outer corneal layer must regenerate, which typically takes one to three weeks. During that healing window, some patients experience light sensitivity and temporary blurring. Both procedures generally require a period of activity modification and follow-up visits to monitor healing progress.
What should I look for when choosing a refractive surgeon?
Board certification in ophthalmology is a foundational credential to verify. Beyond credentials, consider the surgeon’s specific experience with refractive procedures, the technology used, and whether the practice provides thorough preoperative evaluations. A practice with a long-standing community presence and a strong referral-based reputation, as Eastside Eye Physicians has maintained since 1955, may offer additional reassurance that care quality is consistent over time.
Are the long-term results of LASIK and PRK similar?
Research suggests that long-term visual outcomes of LASIK and PRK are comparable for appropriate candidates, though individual results may vary. Both procedures aim to reduce dependence on corrective lenses, and both can provide lasting improvement when the patient is properly selected. Factors such as age-related changes to the lens of the eye, which are separate from corneal refractive error, may affect vision over time regardless of which procedure is performed.
