Tex. Occupations Code § 353.157

(a) A physician, optometrist, or therapeutic optometrist may exclude categories of contact lenses from a contact lens prescription if the exclusion is clinically indicated.

(b) Notwithstanding Section 353.156, a physician, optometrist, or therapeutic optometrist may refuse to give a contact lens prescription to a patient if:

(A) the patient's ocular health would be damaged if the prescription were released to the patient; or

(B) further monitoring of the patient is needed;

(4) the patient has not paid for the examination and fitting or has not paid other financial obligations to the physician, optometrist, or therapeutic optometrist if the patient would have been required to make an immediate or similar payment if the examination revealed that ophthalmic goods were not required; or

(5) the request is made after the first anniversary of the date of the patient's last eye examination.

(c) If a physician, optometrist, or therapeutic optometrist refuses to give a patient the patient's contact lens prescription for a reason permitted under Subsection (b), the physician, optometrist, or therapeutic optometrist must:
