The good news is that six months after Laser Eye Surgery, you can, in most cases, wear coloured or cosmetic contact lenses. You will, however, need to see your optometrist before purchasing any coloured lenses as the shape of your eyes will have changed due to the surgery.
Do not use more medicine or use it more often than your doctor tells you to. If you are wearing contact lenses, remove them before putting the drops in your eyes. Wait at least 5 or 10 minutes after using this medicine before putting them back in. Do not wear contact lenses if your eyes are red.
