The human eyeball was modeled as two intersecting ellipsoidal caps. Both the cornea and sclera were modeled as an ellipsoidal cap, and the two caps were connected at the limbus to form a completely closed shell. The shell coordinates and three Euler's angles were used, which uniquely defined the geometry of the eyeball. Computer programs were written to construct a geometric model of the human eyeball for radial keratotomy.
