There are a number of reasons why LASIK is not typically covered by insurance. First, LASIK is considered an elective procedure, which means that it is not medically necessary. Insurance companies typically only cover procedures that are medically necessary in order to keep costs down. Second, LASIK can be quite expensive, and insurance companies often have strict limits on how much they will cover for any given procedure. Finally, because LASIK is a relatively new technology, many insurance companies have not yet decided whether or not to cover it. In the meantime, patients who want LASIK will need to pay for it out-of-pocket.
