After PRK laser vision correction, vision improves gradually over the first days and weeks, and one of the most practical questions patients ask is when they can get back behind the wheel. The calculator below, the first of its kind, estimates the expected number of days until your vision reaches a level that allows driving, based on research I conducted on tens of thousands of PRK procedures drawn from a database of more than 180,000 laser procedures. Enter your details to receive a personal estimate.
PRK recovery forecast
Estimated time to legal driving vision (binocular uncorrected acuity ≥ 0.5) and to 90% of best-corrected potential (efficacy index ≥ 0.90).
What Does Israeli Law Require in Terms of Vision?
The Ministry of Transport medical examination form for a driving licence sets two vision requirements for a private, group 1 licence: visual acuity of at least 6/12 in one eye, with correction if needed, and a horizontal visual field of at least 120 degrees with both eyes together. A professional licence is stricter: 6/12 in each eye separately and a visual field of 140 degrees. The regulations also cap the difference between the two eyes, which may not exceed 4.5 dioptres.
It is worth understanding what that figure actually means. Visual acuity of 6/12 means that what a person with normal vision sees from twelve metres, you see from six. That is roughly half the vision laser surgery aims for. In other words, the legal fitness threshold for private driving is considerably lower than most patients imagine, and it is tested in one eye only.
These requirements apply to every driver, before surgery and after it. No medical procedure changes them, and they do not depend on which type of surgery you had. In every case it is worth confirming the current wording with the licensing authority, since regulations are updated from time to time.
Why Legal to Drive and Safe to Drive Are Not the Same Date
This is the most important point on this page. Because the legal threshold is relatively low and is measured in one eye, many patients cross it while their vision is still far from stable. The legal test measures visual acuity alone, on a static chart, in good light and at maximum contrast. It does not test the three things that are specifically impaired in the first weeks after PRK: contrast sensitivity, glare tolerance and vision in low light.
The result is that you can meet the legal requirement and still function poorly against oncoming headlights, in rain, at dusk, or entering a dark car park. The medically relevant date is therefore not the date you crossed the threshold, but the date your vision is stable throughout the day, without meaningful fluctuation, and confirmed by an actual examination with your surgeon. The calculator at the top of this page is for planning ahead. It is not permission to drive, and it is not a substitute for an examination.
In practice, most patients return to everyday driving between the end of the first week and the third week, to intercity driving somewhat later, and to extended night driving last of all. Anyone who drives for a living needs to account for the stricter professional licence requirement and plan their return to work accordingly.
The Glasses Restriction on Your Licence, and How to Remove It
If your driving licence carries a restriction requiring you to wear glasses or contact lenses while driving, that restriction does not lapse by itself as a result of surgery. It is recorded on the licence and remains legally binding until it is formally removed, even if your vision is already excellent without them. Driving without correction in that situation is driving contrary to your licence conditions, and in the event of an accident it can create exposure with your insurer as well.
Removing the restriction is a straightforward process: once your vision has stabilized, you undergo a vision test with an optometrist or ophthalmologist, receive a written certificate of your visual acuity, and submit it to the licensing authority together with the appropriate application. It is worth not rushing: have the test only after your prescription has settled, so that you do not have to repeat the process. The exact procedure and forms are published by the licensing authority, and it is advisable to check the current version there before you start.
Which Factors Affect How Quickly You Can Return to Driving?
The research behind this calculator identified several recurring factors. Older age, a higher prescription corrected, higher astigmatism and a larger treatment zone are all associated with slower recovery. The method by which the epithelium was removed, and contact lens wear shortly before surgery, also affect the pace of healing. Younger patients with lower prescriptions, by contrast, tend to return to driving relatively quickly.
A further factor, and sometimes the decisive one, is the condition of the ocular surface before surgery. Dry eye that was not diagnosed and treated in advance prolongs the period of fluctuating vision and worsens the sensation of glare. For that reason my pre-operative assessment includes an evaluation of the tear film, and where necessary surgery is postponed until the dryness has been treated. There is more on this on the dry eye after laser surgery page.
How Can You Speed Up Recovery After PRK?
The most significant factor within your control is adherence to your care instructions. Use the drops exactly according to the schedule you were given rather than according to how you feel, particularly the steroid drops, which are given on a tapering schedule and whose purpose is to prevent corneal haze. Avoid rubbing your eyes entirely, protect your eyes from the sun with UV-filtering sunglasses even on overcast days, and attend every follow-up visit, including when you feel perfectly well.
Adequate sleep, plenty of fluids and reduced screen time in the first days all help the ocular surface heal. Swimming, hot tubs, eye make-up and contact sport are deferred to a date agreed at follow-up. If you experience severe pain that does not subside, a sudden decline in vision after improvement has already occurred, significant redness or discharge from the eye, contact your surgeon immediately rather than waiting for your next appointment.
Additional Tools and Comprehensive Information
If you want to know when 90 percent of your final visual acuity is expected to return, use the vision recovery calculator after PRK as well. A full stage-by-stage recovery timeline appears on the laser vision correction calculators page, and for comprehensive information on the different techniques and the candidacy process, visit the laser vision correction page.
Frequently asked questions
When can you drive after PRK surgery?
There is no single date. Most patients reach vision that allows driving between the end of the first week and the third week, but the decision must be based on an actual vision test and your surgeon's clearance, not on counting days or on a calculator result.
What is the minimum visual acuity for a private driving licence in Israel?
The Ministry of Transport medical examination form requires visual acuity of at least 6/12 in one eye, with correction if needed, and a horizontal visual field of at least 120 degrees with both eyes together. A professional licence is stricter: 6/12 in each eye separately and a visual field of 140 degrees.
If I have passed the legal threshold, does that mean I am ready to drive?
Not necessarily. The legal threshold is relatively low and tests visual acuity alone, in good light, on a static chart. It does not measure contrast sensitivity, glare tolerance or night vision — and those are exactly what are affected in the first weeks after PRK. You can pass the threshold and still see poorly in the dark or against oncoming headlights.
My licence carries a glasses restriction. Does it lapse automatically after surgery?
No. The restriction is recorded on the licence and remains legally binding until it is formally removed. To remove it you need a vision test by an optometrist or ophthalmologist, a written certificate, and submission of that certificate to the licensing authority. Until the process is complete, driving without correction is driving in breach of your licence conditions, with all that this implies for your insurer.
Is it safe to drive at night after PRK?
Night driving is usually the last thing to return. Halos around headlights, glare and reduced vision in low light are common in the first weeks and improve gradually. Even patients who already drive comfortably by day are better off waiting several more weeks before extended driving on unlit roads.
When is the bandage contact lens removed after surgery?
Usually between day three and day five, once the epithelial layer has closed. Removing the lens is a turning point in comfort, but vision continues to clear gradually over the following weeks.
