The Mayo Clinic is supposed to be really good.
I think if your doctor does not tell you the following, you should continue on.
Before surgery, your eye doctor takes a detailed medical history and uses specialized equipment to carefully measure your cornea, noting the shape and any irregularities.
If you wear contact lenses, you'll need to switch to glasses full time a few weeks before this exam. Contact lenses can distort the shape of your cornea, which could lead to inaccurate measurements and a poor surgical outcome.
And things that may prevent you from getting approval for this procedure. I know that my left tear duct is damaged, so I think this would be out of the question for me.
* An immune system disease. Diseases that affect your immune system may impair your ability to heal after surgery. The risks of incomplete healing, infection and other complications are increased whether you have an autoimmune disease, such as rheumatoid arthritis, or an immunodeficiency disease, such as HIV. Taking an immunosuppressive drug also disqualifies you from having this surgery.
* Persistent dry eyes. Any condition that causes dry eyes, including the autoimmune disease Sjogren's syndrome, is likely to impair healing.
* Eye characteristics. An extremely uneven corneal surface or an otherwise abnormally shaped cornea may make surgery more difficult to perform.
* The stability of your vision. If the quality of your vision is fluctuating or progressively worsening, you may not be eligible for LASIK eye surgery.
* Other factors. Your eye doctor will take into account additional factors. For example, deep-set eyes may make the surgery more difficult and risky.
