Abstract
The present disclosure provides a non-invasive technique to determine a true set of refractive indices of a patient's eye in order to generate an accurate model of the patient's eye. Certain aspects provide a system for generating a three-dimensional reconstruction model of a patient's eye. The system includes an imaging device configured to generate first and second measurements of a patient's eye at first and second angles relative to a line of sight of the patient's eye. The system includes an image processor configured to generate a first and second plurality of models of the patient's eye based on applying a plurality of sets of refractive indices to the first and second measurements; identify a first model from the first plurality of models that is congruent with a second model from the second plurality of models; and determine a set of refractive indices associated with the first and second models.
