Robert A. Davis, OD, of The Eye Center in Pembroke Pines, Fla., provides value-added services to patients to keep them from filling their contact lens prescriptions elsewhere. If a contact lens patient's prescription changes, the practice will take back the outdated contact lenses and replace them with the new lenses with no penalty. When patients come in for six-month check-ups, they are given the newest contact lenses to test drive with the old contact lenses taken back simply if the patient likes the newer lenses better. In addition, the practice offers 24/7 emergency services for contact lens patients. Dr. Davis says that if you educate patients about the newest in contact lenses and create a patient-friendly, enthusiastic environment, contact lens patients will stick with your practice.
