Narrator: This is Science Today. Ophthalmologists and patients alike are finding great success with laser surgery to correct vision. But Suzanne Fleiszig, an expert in corneal physiology at the University of California, Berkeley is concerned about the popular procedure.
Fleiszig: It's been shown that there's not that many short term complications of that surgery or worry about what these corneas are going to look like twenty or thirty years down the track. So this is a procedure now being done on young people who may live for a very long time after the surgery. And I'm not convinced that we're not going to see some complications in the future with those people.
Narrator: Since the procedure is irreversible, Fleiszig recommends patients use daily wear contact lenses instead.
Fleiszig: Now, there are some people who may disagree with me on this. But that's my opinion from what I've learned about the cornea and it's a surgical procedure that's not necessary, it's really like a cosmetic procedure because the purpose of it is so that you don't need to wear glasses or contact lenses.
