Each vision therapy program is customized to that particular patient’s needs. A comprehensive therapy program may last between 15 and 40 weeks – however it’s really up to the patient and family to choose the number and frequency of sessions. A patient typically has weekly, one-on-one in-office sessions for 60 minutes. The patient will also be assigned homework activities to be completed four times between in-office sessions. Homework participation is critical to each program and shows more rapid results and sometimes shorter programs of therapy.
