The present disclosure generally relates to a system and method of authenticating a provider prior to performing a procedure. The system includes an optometric or ophthalmic device, an iris imager, and one or more processors. The one or more processors acquire, using the iris imager, an image of an iris of a provider, and attempt to authenticate the provider using a comparison of the image of the iris with a reference iris scan of the provider. Responsive to authenticating the provider, the one or more processors access a set of one or more procedures approved for the provider. Responsive to determining that a procedure is included in the set of one or more procedures, the one or more processors configure operation of the optometric or ophthalmic device to perform the procedure.
