(a) If a patient presents a contact lens prescription to be filled or asks a person who dispenses contact lenses to verify a contact lens prescription under Section 353.1015, but requests that fewer than the total number of lenses authorized by the prescription be dispensed, the person dispensing the lenses shall note on the prescription or verification:
(1) the number of lenses dispensed;
(2) the number of lenses that remain eligible to be dispensed under the prescription; and
(3) the name, address, and telephone number of the person dispensing the lenses.
(b) A notation under Subsection (a) is a permanent modification of the prescription. Except as provided by this subsection, a contact lens prescription may not be modified.
(c) The person dispensing the lenses shall:
(1) maintain a photocopy of the prescription or verification, as modified, in the person's records as if the copy were the prescription to be filled; and
(2) return a prescription to the patient so that the patient may have the additional lenses dispensed elsewhere.
