When can I use screens after PRK?

General information about typical recovery, not medical advice. Every eye and every surgery is different, and your surgeon's instructions override anything on this page. Read our full disclaimer.

Short answer

As soon as it is comfortable, which for most people is a few days. Screens do not slow healing, but blur and dryness make them hard early on.

No published source says screens harm a healing cornea after PRK. The limit is comfort, not damage.

Two things get in the way in the first days. StatPearls describes blurred vision, light sensitivity, and transient ghosting or glare through days 1 to 3, and EyeWiki puts peak discomfort at days 2 to 3 with tearing and light sensitivity. Most people simply cannot look at a bright screen through that. The American Academy of Ophthalmology says vision gradually improves over about 3 to 5 days, which is roughly when screen use becomes tolerable for many.

After that, dryness is the issue. StatPearls lists dry eye as one of the most common complications after laser refractive surgery, and people blink less while staring at screens, which makes vision fluctuate. Use your lubricating drops before you start, turn brightness down, increase text size, and take breaks. If your vision blurs while you are working and clears when you blink hard, that is usually dryness rather than a problem with the surgery.

When	Typical guidance
Days 1-3	Most people cannot tolerate screens. Rest instead.
Days 4-7	Short sessions become possible for many, with larger text and low brightness.
Week 2 onward	Normal use for most desk workers, with frequent lubricating drops and breaks.

Call your surgeon now if you notice any of these

Severe or worsening eye pain after day 3 or 4, when pain should be easing rather than increasing
Pain that is not helped by your prescribed medicine or by over the counter medicine
Thick yellow, green, or crusting discharge from the eye
Vision that suddenly gets worse after it had been improving
A new white or cloudy spot visible on the cornea
The bandage contact lens falls out, folds, or moves off center before your surgeon removes it
A sudden sharp pain on waking or on opening the eye, which can signal a recurrent corneal erosion
Increasing redness, swelling of the lids, or increasing light sensitivity after the first few days
Any new flashes of light, a shower of floaters, or a curtain or shadow across your vision

These warning signs after PRK can point to problems that need same-day care. Do not wait for your next scheduled visit. If you cannot reach your surgeon's office, use their on-call line, or go to an emergency room.
