Calculate the central magnification of an eye - camera system

This integration demonstrates how PAROS can be used to calculate the central magnification of a fundus image. More information can be found at our GitHub repository.

To calculate the magnification of a fundus image, enter the parameters of the eye in the calculator below. If you do not have all required parameters, it is possible to estimate some parameters:

• The posterior corneal curvature can be estimated as 0.81 x anterior corneal curvature. To do this, click the Estimate posterior corneal curvature button.
• The posterior lens curvature can be fitted from the spherical equivalent of refraction. To do this, click the Fit posterior lens curvature button.
