How long does it take to see clearly after PRK?
Vision usually improves over the first week as the surface layer regrows, and then continues to settle over weeks to months. It is normal for the two eyes to recover at different speeds, and for vision to fluctuate while they do.

In more detail
The reason clinics are specific about the first days after surface treatment is that the eye is uncomfortable while the surface heals, and this is when people are most likely to wonder whether something is wrong. It is also the period when the eye is most vulnerable to infection, which is why the instructions are strict.
What this answer depends on
- The size of the prescription treated
- How the surface heals in your case
- Whether you use the prescribed drops as directed
