K.S.A. 65-4966

Each patient shall be entitled to receive a copy of such patient's contact lens prescription once the same prescription has been determined and the adaptation period has been completed. Any prescription for a specific brand of contact lenses available only from the licensed optometrist or person licensed to practice medicine and surgery, but which are generally marketed under an alternate brand, must disclose the name of the manufacturer and the trade name of the alternate brand. No contact lens prescription may be limited by an expiration date or otherwise to a period of less than 12 months from either the date the prescription is first determined or the last date of the contact lens evaluation by a licensed optometrist or a person licensed to practice medicine and surgery, whichever date is later, unless a health related reason for the limitation is noted in the patient's medical record.
