How long until i can see clearly after a flap revision (post ilasik)?

Unknown: Really depends on why you had the revision---if the central flap is clear--vision should return in just a week or two.

Time can be variable: Some of it depends on why the flap was lifted and how long that problem takes to resolve. Some flap lifts see "perfect" the next day, others may take days or more than a week to clear. If vision stays blurred there may be additional problems under the flap. Ask your doctor to explain why the flap was lifted.
