The FTC is publishing a final rule to implement amendments to the Contact Lens Rule. These amendments require that prescribing eye care practitioners obtain a confirmation of prescription release from patients after releasing a contact lens prescription and maintain each such acknowledgment for a period of not less than three years. The Commission is permitting prescribers to comply with automatic prescription release via electronic delivery in certain circumstances. Further, these amendments specify a time period for prescribers to respond to requests for prescriptions; clarify and institute additional requirements for automated telephone verification messages; more precisely delineate what constitutes unlawful alteration of a prescription; and require that sellers provide a method for, and notice of the method for, patient prescription presentation.
