PostOp Eyes

When can I be in sunlight 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

You can go outside right away, but wear UV blocking sunglasses, often for around 6 months, because UV exposure raises the risk of corneal haze.

This is the one activity where PRK has a clear, strongly stated published rule. The American Academy of Ophthalmology says that after PRK you will need to wear sunglasses outside for as long as your doctor tells you, because sun exposure can lead to corneal scarring after surgery.

The concern is corneal haze, a cloudiness in the healing tissue that can dim vision. StatPearls says haze typically peaks at 1 to 2 months after laser refractive surgery and clears over 6 to 12 months, and advises UV protective sunglasses for 6 months after surgery, especially at high altitudes, to help prevent the correction from regressing. The American Academy of Ophthalmology's surface ablation guidance lists UV protection alongside mitomycin C and steroid drops as haze prevention measures, and advises UV protecting eyewear during the year following treatment.

Practically, that means wraparound or large UV blocking sunglasses whenever you are outdoors in daylight, including on cloudy days, at the beach, on the water, and especially skiing or at altitude. Light sensitivity in the first days also makes sunglasses a comfort item, not just a protective one.
