How much time does PRK / ASA surgery take?
The PRK / ASA surgery and recovery period takes longer than LASIK does. The actual procedure takes just a few minutes, and both eyes can be treated during the same visit. But following surgery, you must wear a protective contact lens for several days. Eyedrops must be used frequently for the first four to five days and periodically for up to several weeks. Visual recovery also takes longer than with LASIK.
