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.

How do doctors perform open heart surgery?

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.

What are the causes of Crohn's disease and ulcerative colitis?

Genes+environment : A combination of genetic predisposion (for example Crohn's is more common in ashkenazi jews), life events (eg appendectomy increases one and decreases the other), and environmental influences (eg smoking increases Crohn's and decreases severity of uc...). Bet you didn't expect the latter! as knowledge increases more precise factors are identified.

2 complex tosay here: Depends on extent of disease, severity of disease, response to meds. Diet may affect symptoms, more so than inflammation. Lots of medical rx available, including oral, rectal meds. Can include steroids, antiinflammatories, immune modulators, biologics, antibiotics, probiotics, and surgery. See your md/gi md for specifics.
