3-Arc Refractive Surgery: Computational Simulation

A triple arc-incision refractive surgery is proposed and studied by means of computational simulations. Parametric studies of four geometrical conditions of the surgery are performed in order to determine their effect on the curvature of the cornea. Corneal positive and negative curvature changes are observed indicating the surgery may simultaneously correct both hyperopia and presbyopia. Comparison to clinical cases confirms not only the accuracy of the simulations, but also de potential of the surgery for the simultaneous correction of different ametropies.
