Empirical Fitting Guide
Diameter Selection
- Use the 14.5 diameter for normal-sized corneas
- If a different diameter is desired, add 3.5mm to the HVID to calculate the lens diameter
Base Curve Selection
- Use the chart to select the base curve based on the diameter and average K reading
Power Determination
- Use standard vertex adjustment to convert the spectacle Rx, or call our consultants and let us do it for you
Adjustments (when necessary)
- When evaluating the fit of the lens, please provide our consultants with the following data:
- Fit/movement (base curve evaluation)
- Lens overlap (diameter evaluation)
- Orientation, in 1° increments if possible
- Over-refraction
- We’ll calculate the Rx for you
