The document summarizes the PHSI program which provides hearing evaluations and treatment in ophthalmology practices. Key points include that 50% of older adults have hearing loss, which is linked to depression, cognitive decline, and other issues. The program trains practices to market, screen, refer, and fit patients with hearing aids. Practices can expect to generate over $500k in net income annually with an initial investment of around $32k and minimal space needs. PHSI handles equipment, training, and ongoing support so practices have full ownership and control.
