Most people heal enough after PRK to see clearly within about a month, but complete healing takes around three months. Unlike LASIK, PRK removes the outer layer of the cornea (the epithelium), which needs to regrow from scratch. That regrowth process is why recovery feels slower and more uncomfortable, even though the long-term visual outcomes are comparable.
The First Week: Surface Healing
The most critical phase of PRK recovery is the first five to seven days, when the epithelium regenerates across the corneal surface. Your surgeon places a bandage contact lens over the eye immediately after the procedure to protect this raw surface while new cells migrate in. That lens typically stays in place until the epithelium has closed over, which takes about a week for most people. Some patients heal in as few as three days, but a full week is common.
During this window, your vision will be noticeably blurry. At the one-week mark, you can expect something in the range of 20/50 to 20/60, which is a dramatic improvement over uncorrected vision but still far from sharp. Most people can see well enough to drive by the end of the first week, though many prefer to wait a bit longer.
Pain Peaks Around Days Two and Three
The discomfort after PRK is the part most people underestimate. Pain begins shortly after the procedure, once the numbing drops wear off, and builds over the next day or two. In a clinical survey, about 51% of patients reported their worst pain between 24 and 48 hours post-surgery, and another 34% said it peaked between 48 and 72 hours. By day five, once the epithelium has largely regrown, the acute pain phase is usually over.
The sensation varies. Some people describe it as a gritty, burning feeling, like having sand stuck under a contact lens. Others report sharper, more intense pain, especially on day two. Your surgeon will prescribe eye drops to manage inflammation and may recommend oral pain relief for those first few days. Keeping your eyes closed, staying in a dimly lit room, and sleeping as much as possible during days two and three makes a real difference.
Weeks Two Through Four: Vision Sharpens Gradually
Once the bandage lens comes off and the surface has healed, your vision will continue improving, though not in a straight line. Many people notice fluctuations throughout the day, with vision clearer in the morning and hazier by evening. This is normal and reflects ongoing changes in the corneal surface as it smooths out and stabilizes.
Most patients see very well within a month of the procedure. You’ll likely still notice some softness or slight blur compared to what glasses or contacts gave you before, but daily tasks like reading, working on a computer, and driving become comfortable for most people during this period.
You’ll also be using prescription eye drops during this time. Steroid drops are typically tapered over about three months to control inflammation and reduce the risk of corneal haze, a faint clouding that can develop as the cornea heals. Surgeons often apply a medication during the procedure itself to further lower the risk of haze, and studies confirm this significantly reduces its occurrence.
Dry Eyes and Night Vision Changes
Nearly all patients experience some degree of dry eye immediately after PRK. About 60% still notice dryness a month out. This happens because the healing process temporarily disrupts the corneal nerves that signal your eyes to produce tears. Corneal sensitivity typically rebounds to near-normal levels by three months, and for most people, dry eye symptoms return to their pre-surgery baseline within a year. Preservative-free artificial tears will be a constant companion during recovery, especially in the first few months.
Halos and glare around lights at night are also common in the early weeks. These visual disturbances gradually fade as the corneal surface stabilizes. For most people, they resolve by the three-month mark, though in some cases they linger a bit longer.
Three Months: Full Healing
The three-month point is when most surgeons consider healing complete. By this stage, your refraction has typically stabilized, meaning your prescription is close to its final result. One Cleveland Clinic patient reported 20/16 vision at the three-month follow-up, slightly better than 20/20. While not everyone achieves that, it illustrates the kind of outcome PRK can deliver once the cornea has fully settled.
Some patients, particularly those who had higher prescriptions corrected, may continue to see minor refinements in clarity out to six months. But for the majority, the three-month visit is the one where your surgeon confirms everything looks stable.
Activity Restrictions During Recovery
Your daily routine will have some limits during the first month. Based on guidelines from Walter Reed National Military Medical Center:
- Eye makeup: Wait at least two weeks. Discard old products and start with fresh ones to avoid infection.
- Swimming, hot tubs, lakes, and oceans: Wait one month. Contaminated water poses an infection risk to the healing cornea.
- Contact sports and vigorous exercise: Wait one month. This includes basketball, martial arts, wrestling, and similar activities where you could take a hit to the face.
Light exercise like walking is generally fine within the first week, but anything that causes heavy sweating or risks getting sweat in your eyes should wait at least a few days after the bandage lens is removed. Screen time is possible within the first week, though your eyes will fatigue quickly. Take frequent breaks and keep artificial tears nearby.
How PRK Healing Compares to LASIK
The reason PRK recovery feels long is that LASIK has set expectations for laser eye surgery. LASIK creates a flap in the cornea rather than removing the surface, so most LASIK patients see clearly within 24 hours and have minimal pain. PRK trades that fast recovery for some structural advantages: no flap means no flap-related complications, and the cornea retains more of its structural strength. That’s why PRK is often preferred for people with thinner corneas, those in military or law enforcement roles, and anyone at higher risk of eye trauma.
The final visual outcomes are essentially the same. PRK just requires more patience getting there. If you’re comparing the two, the question is really whether you’d rather have a faster recovery or avoid the small risks associated with a corneal flap.
