    Expert Answer
    LASIK isn't usually right for people with a low prescription or a hyperopic (+) prescription. Your doctor might decide to postpone your LASIK surgery if your prescription has changed by .75 diopters in the last 2 years. Additionally, LASIK may not be right for you if you have an eye disease or eye problems, like dry eyes.

    There are a number of criteria a patient must meet to be a good candidate for LASIK, including having an appropriate prescription—typically a myopic/near-sighted Rx at a level of about a -3.00 to -7.00, with mild to moderate astigmatism. You must also have healthy eyes and a stable Rx, and ideally be between the ages 25 and 40.

    The benefits are improved distance vision and lower dependence on glasses or contact lenses. The risks are generally pretty low with modern surgical techniques, but they can include dryness, glare when driving at night, bleeding, infection, loss of vision, and corneal issues like keratokonus and corneal ecstasia.

    Expert Answer
    There's a long list of conditions that can affect LASIK, which is why you should be screened at a reputable center. For instance, you shouldn't get LASIK if your cornea is misshapen. This can occur if you have a condition like chronic allergies and you've rubbed your eyes a lot, because your cornea can thin and distort over time with vigorous rubbing.
