Visual Optics

With our MRI protocols, we can accurately determine the 3D shape of the eye. This allows us to make patient-specific eye models which we can use to determine various optical characteristics of the eye through ray tracing simulations. When we used these techniques to study the eyes of patients with Negative Dysphotopsia, we discovered that their burdensome loss of peripheral vision was caused by light rays missing the edge of the implanted lens.

We are currently extending these techniques to accurately correlate the location on fundus photographs to the 3D location of the retina, enabling a more accurate use of these images for radiotherapy planning. To perform these simulations in an accurate and reproducible way, we have developed ZOSPy, an open source Python-based interface to OpticStudio.
