Why do I have to remove my contacts before my exam and before surgery?

Contact lenses can alter the shape of your cornea and can also prohibit oxygen flow to the cornea. For that reason, we ask that you refrain from wearing them both before your Brinton Vision Ocular Analysis (BVOA) and before surgery. Soft lenses should be removed three days before your exam, and seven days prior if you wear toric lenses. If you wear rigid gas-permeable or hybrid lenses, leave them out at least 30 days prior to your exam. This is so that your cornea can be restored to a more natural shape before measurements are taken.
