Patient-specific three-dimensional eye models
obtained using very high resolution scans on a human 7T MRI system have been
shown to form a much more accurate input for ray tracing algorithms than the
current state-of-the-art generalized eye models used for clinical ophthalmology.
Using a cued-blink protocol, custom-built phased array coil and segmentation
software, accuracy of less than one-half dioptre can be achieved using the MRI
data. These patient-specific models should provide much improved input for
therapeutic procedures such as intra-ocular lens replacement for post-cataract
surgery.
