This bill amends provisions of the law governing optometrists. The bill provides a more detailed explanation of what constitutes the practice of optometry. The definition of "practice of optometry" in current law does not include surgical procedures. Under the bill, certain types of ophthalmic surgeries are included in the practice of optometry and certain procedures are specifically excluded. An optometrist may only perform ophthalmic surgery if the optometrist meets credentialing requirements established by the State Board of Optometry. The bill also broadens the authority of an optometrist to dispense drugs by expanding the types of drugs an optometrist may dispense to include schedule II narcotics limited to pharmaceuticals containing specified doses of hydrocodone combined with doses of another drug and by removing language that prohibits an optometrist from administering drugs by injection or intravenously. The bill directs the board to adopt rules to further define the scope of practice of optometry and establish credentialing requirements for surgical procedures. The bill clarifies that the board, and no other board or commission in the State, has the authority to define the scope of practice of optometry and to exercise the powers of the board. The bill authorizes the board to issue advisory opinions and declaratory rulings. The bill also makes minor changes to the provisions relating to telehealth services and filling contact lense and spectacle prescriptions.
