title: Learning the "numbers game" of today's contact lens fitting: clinical and business pearls.
abstract: A "chair time model" for contact lens pricing is a valuable administrative tool. Relative sagittal depth is an easy comparison to use when evaluating the theoretical fit of one soft lens versus another. Biological oxygen apparent transmissibility (BOAT) and a calculated value of oxygen transmissibility (Dk/L) are two totally different assessments and the significance of BOAT will need to be clinically tested over time.
