Most people qualify for LASIK, but not everyone is an ideal candidate. To be a good candidate for LASIK, your surgeon will need to ensure that your eyes, body, and overall health are such that you’re eligible for the procedure. First, you must be at least 18 years old and at a point where your hormones and vision have stabilized—for this reason, pregnant and nursing patients should consider waiting until menstruation has returned to normal. Additionally, you should be in good overall health, as a compromised immune system or conditions like uncontrolled diabetes could increase the risks involved with surgery. Finally, your eyes should be healthy and free of disease and injury, and your corneas should be at least 0.5mm thick.
