How long will it take for me to see clearly after prk?

It depends: Prk has a longer visual recovery than lasik. Like the epidermis of the skin, the cornea has an outer (epithelial) layer that takes around 5 days to regenerate after prk. Many patients wear a contact lens continually for 5 days to speed up this recovery. After the lens is removed, vision can still further improve and get darker and crisper for weeks or months, depending on the level of correction.

Variable: Depends on many factors, including if any prescription remains, amount and type of prescription treated, your body healing characteristics, any present dryness. In general, most people are clear enough in a few days to work, etc but healing and improved vision may continue for several weeks and even over a few months.

About a week: While everyone heals at their own speed, generally between days 5-7 the front surface of the cornea has healed and you will have functional vision. There is still a lot of healing that needs to happen though and it may take several months for the full effect of PRK to be realized.
