A mechanical model for radial keratotomy: toward a predictive capability.
A detailed three-dimensional finite element model for radial keratotomy has been developed. The model includes the full load-bearing tunic of the eye and employs realistic geometry. Incisions are modeled explicitly, and material parameters are obtained from in vivo data. Calculated results obtained with the model are compared with data from two independent medical studies on radial keratotomy.
