When it comes to laser vision correction, the LASIK vs PRK comparison is the question most patients ask first, and for good reason, since both are established options that work exceptionally well. LASIK uses a thin corneal flap to access and reshape the underlying tissue, while PRK removes the corneal epithelium entirely, allowing the eye to heal from the outside in. The result of either procedure is the same: sharper, clearer vision with far less dependence on glasses or contact lenses.
The decision between them isn’t about which is “better.” It’s about which one is better for you based on your corneal anatomy, occupation, activity level, and how quickly you need your vision back. This guide walks through each factor clearly so that you can enter a consultation already informed.
Key Takeaways
- LASIK restores functional vision within 24–48 hours; PRK requires a minimum of 5–7 days off work.
- PRK eliminates all flap-related risks, making it the choice for athletes and high-impact occupations.
- Both procedures use the same excimer laser and achieve comparable long-term visual acuity results.
- Corneal thickness and lifestyle are the primary factors that determine which procedure you qualify for.
- Both LASIK and PRK can save thousands of dollars over a lifetime compared to contacts and glasses.
The Recovery Showdown: Are you okay with taking a week off, or do you need your vision back tomorrow?
The recovery timeline is where LASIK and PRK differ most noticeably. Your work schedule, family obligations, and daily routine should all factor into this decision, not just the surgery itself.
LASIK: Back to your life in 24–48 hours
Most LASIK patients wake up the morning after surgery with noticeably improved vision. Mild light sensitivity and a foreign-body sensation are common on day one, but functional vision (enough to drive, work, and use screens) returns quickly for most people.
By the end of the first week, the majority of patients are back to normal work and daily activities. Computer use becomes comfortable, though artificial tears are typically recommended to manage temporary dry eye symptoms during the healing process. As Cleveland Clinic notes, LASIK’s faster recovery makes it a practical choice for patients who cannot afford extended downtime from work or daily responsibilities.
Key post-operative care reminders for LASIK:
- Avoid rubbing your eyes for at least one month. This protects the healing corneal flap
- No swimming or hot tubs for one week minimum
- Use prescription eye drops as directed for 1–2 weeks
- Contact sports can resume once your surgeon provides clearance
PRK: Slower to heal, but worth the wait for some people
The first few days after PRK involve more noticeable discomfort. A bandage contact lens is placed over the eye to protect the surface while new epithelial cells regenerate, a process that typically takes three to five days. Light sensitivity during this window can be significant.
Vision gradually sharpens over weeks two through six, though it may fluctuate day to day. This is a normal part of the healing process, not a sign of complications. By months two to three, final visual quality often rivals or exceeds LASIK outcomes.
What to expect during PRK recovery:
- Plan for 5–7 days away from work at a minimum
- Wear dark sunglasses outdoors; light sensitivity is real and persistent early on
- Use artificial tears frequently throughout the day
- No permanent flap restrictions after the surface heals completely
Final PRK results at months two to three often rival or exceed those of LASIK, although that slower road leads to the same destination.
Those of could LASIK actually be wrong for you? Here’s Who Should Choose PRK Instead
Most people assume LASIK is the default option. But your anatomy and lifestyle may point you in a different direction entirely, and choosing the wrong procedure can affect both your results and your long-term eye health.
You’re probably a great LASIK candidate if…
LASIK works best when certain baseline criteria are met. Your surgeon will confirm eligibility with corneal topography and a thorough exam, but these are the general markers:
- Your corneas are thick enough to accommodate flap creation safely
- Your prescription has been stable for at least 12 months
- You work primarily indoors with limited risk of eye trauma
- You don’t have significant dry eye disease or pre-existing corneal conditions
- You need your vision back quickly for professional or personal reasons.
PRK might be the better call if…
PRK is not the backup plan. For many patients, it’s the clinically smarter choice. Because no flap is created, it preserves more corneal tissue and eliminates an entire category of risk. According to NIH’s clinical review of photorefractive keratectomy, PRK is the specifically recommended for patients with occupational or lifestyle factors that pose a risk to corneal flap integrity — including military personnel, contact sport athletes, and law enforcement officers.
- Your corneas are thinner and may not meet LASIK thickness requirements
- You play contact sports or participate in activities with a risk of eye impact
- You work in the military, law enforcement, or other high-risk occupations
- You have a history of prior corneal issues or surface irregularities
- Your refractive errors are on the higher end of the correctable range
PRK isn’t the “worst” option. For many people, it’s the safer one.
Is LASIK or PRK actually worth the money? The Numbers Might Surprise You
Both procedures typically cost between $4,500–$5,500 for both eyes, a number that sounds significant until you calculate what you’re already spending on vision correction every year.
What contacts actually cost you over a lifetime
Daily and monthly contact lenses, lens solution, storage cases, annual exams, and emergency replacements add up steadily. University of Utah Health reports that contact lens wearers may spend upwards of $60,000 over their lifetime when all related costs are included.
Beyond the dollar figure, there’s a health cost too. The CDC estimates nearly one million healthcare visits annually are linked to contact lens-related eye infections, generating significant out-of-pocket treatment costs that most people never factor into their comparison.
Most LASIK and PRK patients break even within 7–10 years. Every year after that is pure savings.
Which procedure is safer? Here’s the Honest Comparison Nobody Talks About
Both LASIK and PRK have strong, well-documented safety records. The meaningful difference isn’t the overall risk level; it’s the type of risk each procedure carries.
LASIK: Highly proven, with one thing to know
LASIK has decades of clinical data supporting its safety and effectiveness. Flap-related complications occur in fewer than 1% of cases with modern femtosecond laser technology, and infection rates are extremely low. However, a comprehensive review of LASIK complications published in NIH/PubMed identifies flap dislocation, diffuse lamellar keratitis, and post-operative dry eye as the most documented adverse outcomes, all of which are manageable but worth understanding before surgery.
The most common side effects are temporary: dry eyes, halos around lights, and mild changes in night vision. These typically resolve within three to six months as the healing process completes. Artificial tears and scheduled post-op check-ins help manage symptoms during this window.
PRK: No flap, no flap problems
Because no corneal flap is created, PRK carries zero risk of flap dislocation, even from a direct blow to the eye. This matters enormously for anyone in a high-impact sport or profession. PRK also tends to cause less disruption to the corneal nerves near the surface, which may reduce the risk of postoperative dry eye disease compared with LASIK.
PRK also preserves more corneal tissue overall, which supports long-term corneal stability and reduces the risk of conditions such as corneal ectasia in susceptible eyes.
For people in high-impact jobs, contact sports, or with pre-existing dry eye concerns, PRK’s profile is often the smarter long-term call.
The Hardest Part of Laser Eye Surgery Is Deciding to Do It. You’re Already There
A comprehensive eye examination with corneal topography mapping provides essential data for selecting procedures. Advanced diagnostic testing reveals corneal thickness, surface irregularities, and tear film quality.
Discussion of lifestyle factors and realistic expectations ensures appropriate procedure matching. Both LASIK and PRK offer excellent long-term visual outcomes when properly selected.

FAQs
How long do LASIK and PRK results last?
Both procedures provide permanent correction of the treated refractive errors. Your vision won’t “revert” to what it was before surgery. That said, age-related changes, like the gradual decline in close-up reading vision known as presbyopia, typically begin in the mid-40s and are unrelated to the surgery itself. As outlined in NIH’s clinical overview of LASIK, most patients enjoy stable distance vision for decades following either procedure.
Can both eyes be done on the same day?
Yes, bilateral same-day surgery is standard practice for both LASIK and PRK. Having both eyes treated at once minimizes your total recovery period and reduces the number of surgical appointments needed. Your surgeon will assess your individual case to confirm this is appropriate for you.
What if my vision changes after surgery?
Significant vision changes after healing can often be addressed with an enhancement procedure. Most surgeons offer enhancement guarantees within the first year of surgery. Minor fluctuations in the weeks following PRK are a normal part of the recovery timeline and not a sign that something went wrong. Your post-op check-in appointments are specifically designed to monitor for this.
Is there an age limit for LASIK or PRK?
Patients must be at least 18 years old and have a stable prescription for at least 12 months. There’s no strict upper age limit, though presbyopia considerations become relevant after 40. Many patients in their 50s and 60s successfully undergo laser vision correction. The right candidate is determined more by eye health than by age.
How much do LASIK and PRK typically cost, and is it worth it?
Both procedures generally range from $4,500 to $5,500 for both eyes, depending on the technology used and your surgeon’s experience. That number looks different when you factor in that the average contact lens wearer may spend well over $60,000 on lenses, solutions, and exams across a lifetime, a comparison that University of Utah Health has outlined in detail. On top of that, the CDC reports that contact lens-related infections result in nearly 1 million medical visits per year — an ongoing, hidden cost most wearers overlook.
