Depends: If you have a healed small peripheral corneal ulcer that is well healed yes. But if the scar is where the flap is made and is involved more than 75 microns of superficial cornea then most surgeon prefer to do prk so the flap does not become irregular or button holed. That is true even with femtosecond laser flap maker.

A 35-year-old member asked:

How do doctors perform open heart surgery?

Dr. Louis Grenzer
Cardiology 55 years experience
Bypass: Blood returning to the heart is diverted and run through a machine that performs the function of the lungs (add oxygen to the blood) and then the blood is directed back to the arterial side of the circulation. So the blood bypasses the heart. This is necessary for operations such as replacing a valve. As the blood is not passing through the heart, the heart can be stopped during the surgery.
