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.
