PRK: Are both eyes treated at the same time?

In general most refractive surgeons will do both eyes the same day. This is perfectly safe and makes the recovery of visual function quicker. 

In the early days of PRK, we treated one eye at a time.  Now almost always, we treat both together.  It is a very safe procedure and most people don't want to go through the recovery process two times.   With that said, it is always possible to do one eye at a time.  If a retreatment  is necessary in both eyes, we generally only retreat one eye at a time because in this subset of patients (less than 2%) their response to the initial treatment was not as predictable as the general population.
