Most people can start driving again about one week after PRK, though some need closer to two weeks. The key factor is whether your vision has recovered enough to meet the legal driving standard of 20/40 in your better eye, which is the minimum in nearly every U.S. state. Your surgeon will check your vision at your first follow-up appointment and let you know when you’re cleared.
The First Week: Why You Can’t Drive Yet
PRK removes the outer layer of your cornea so the laser can reshape the tissue underneath. That outer layer then has to grow back on its own, which takes about four to five days. During this time, you’ll wear a bandage contact lens to protect the healing surface, and your vision will be too blurry to safely operate a car. Light sensitivity, tearing, and discomfort are common in the first 24 to 48 hours, making driving impractical even if you could see well enough.
By days four or five, the corneal surface has typically closed over, and you may start feeling more comfortable. But the healing tissue is still smoothing out, and your vision won’t be stable yet. Cleveland Clinic advises avoiding driving for at least the first few days and not resuming until your provider gives the go-ahead.
When Most People Start Driving Again
At the one-week follow-up, your surgeon will test your visual acuity. About 95% of PRK patients reach 20/40 vision or better by this point, which is the threshold required to legally drive in almost every state (Georgia, New Jersey, and Wyoming allow slightly lower acuity). If you hit that mark, you’re technically legal to drive during the day.
“Technically legal” and “comfortable behind the wheel” aren’t the same thing, though. Your vision will still fluctuate throughout the day during the first month, and many people find that their eyesight is sharper in the morning and fuzzier by afternoon. One Cleveland Clinic patient who was cleared at one week waited until week two to actually drive, starting with familiar routes. That’s a common approach. You’ll know you’re ready when road signs look crisp and you feel confident judging distances.
Night Driving Takes Longer
Even after you’re comfortable driving during the day, nighttime is a different story. Halos around headlights and streetlights, starbursts, and glare are extremely common in the weeks following PRK. At six months post-surgery, one study found that 45% of patients still reported some degree of nighttime visual disturbance, with about 11% describing it as significant.
There are two distinct types of disturbance. Starbursts, the spiky rays you see radiating from light sources, are caused by corneal haze and tend to fade as the cornea heals. Halos, the soft rings of blur around lights, result from the transition zone between treated and untreated cornea and can linger longer. Most surgeons recommend avoiding night driving for at least the first few weeks, and many patients choose to wait a month or more before they feel confident on dark roads.
How PRK Compares to LASIK Recovery
If you’ve heard that LASIK patients drive the next day and wondered why PRK takes so much longer, it comes down to the healing process. LASIK creates a flap in the cornea rather than removing the surface layer, so the eye doesn’t need to regenerate tissue. Most LASIK patients see clearly within a day or two. PRK patients typically need about a month for vision to fully stabilize, though functional driving vision usually arrives much sooner, within one to two weeks.
The tradeoff is that PRK avoids flap-related complications entirely, which is why it’s often recommended for people with thinner corneas or those in contact sports and military roles. The slower recovery is the main downside, but the long-term visual outcomes are comparable.
Tips for Your First Drives
When you do get behind the wheel again, a few things will make the transition easier. Sunglasses are essential. Your eyes will be more sensitive to light than usual for weeks after surgery, and bright sunlight or oncoming headlights can cause squinting and watering that makes it hard to focus. The sunglasses your surgeon provides in your post-op kit are a good starting point, but any pair with UV protection works.
Dry eyes can also affect your comfort and clarity while driving. Most patients experience dryness for up to three or four months after PRK. Keep artificial tears in your car and use them before you start driving if your eyes feel gritty or your vision seems hazy. Blinking more frequently helps too, since people tend to blink less when concentrating on the road.
Start with short, familiar routes during daylight hours. Avoid highways and heavy traffic until you’re confident in your reaction time and depth perception. Your vision may be slightly different from hour to hour during the first month, so pay attention to how your eyes feel before each trip rather than assuming yesterday’s clarity will carry over.
What Affects Your Personal Timeline
Not everyone heals at the same rate. The speed of corneal regrowth varies from person to person, and research shows that faster healing correlates with better early visual outcomes. Your original prescription matters too. People correcting higher levels of nearsightedness tend to have slightly longer recovery periods because more corneal tissue was reshaped.
Age, overall eye health, and how closely you follow post-op instructions (using prescribed drops, avoiding rubbing your eyes, protecting against UV light) all play a role. Some people drive comfortably at five days. Others prefer to wait two or three weeks. The best gauge is your own visual comfort and your surgeon’s assessment at follow-up visits, not a fixed calendar date.
