How patient axial length, corneal power and effective lens position affect the add power of a multifocal lens

This calculator gives you an idea how the patient axial length, corneal power and effective lens position affect the add power in the corneal plane and how the effect add power of the multifocal IOL on the corneal plane impact the reading distance for the patient.
