Which fitting method uses information from the pre-fit examination so that the lenses are placed at the dispensing visit?

• A. Diagnostically
• B. Empirically
• C. Pre-fit method
• D. Post-fit method

Answer: (B)

Empirical fitting is the approach that uses information gathered before fitting to predict the best initial lenses so they can be dispensed at the dispensing visit. It relies on measurements from the pre-fit exam—such as corneal curvature, diameter considerations, refractive error, and wearing history—and applies established fitting guides or nomograms to select the base curve, diameter, and power. Because these data-driven predictions are used, the lenses can be ordered and ready to fit right away when the patient comes in, reducing or eliminating the need to trial multiple lenses during the dispensing visit. Diagnostically fitting would involve trying lenses during the visit to judge fit and vision and adjust accordingly. Post-fit methods focus on making adjustments after the patient has worn the lenses. The pre-fit method isn’t the standard approach for ensuring immediate dispensing, so empirical fitting best matches how the information from the pre-fit examination is used.
