To approach an operation, especially one where they slice up your eyes, like it's a haircut seems.... naive, at best.

Not if you know nothing about the operation. People have to trust their doctors, just like they have to trust anyone who is an expert in things they don't understand. Whether it's prescribing a medication, or performing surgery, I accept that my doctor is the expert and I'm not.

If you trust your doctor, and your doctor convinces you that the procedure is as simple as a haircut, it's the doctor's fault, not yours.
