ABSTRACT:
Contact lenses, such as prism ballasted toric lenses, having anterior and posterior surfaces related by way of non-axisymmetric thickness variation can exhibit a third-order aberration, particularly vertical coma. A wavefront modifier, such as an aspheric surface modification, is incorporated into the lenses to at least partially compensate for the wavefront aberration associated with the non-axisymmetric thickness variation. A magnitude of the modifications can be adjusted to set a target value for any remaining wavefront aberration of the lenses based on a population-wide goal.
