anterior curvature

The lens capsule may be involved with the higher anterior curvature than posterior of the lens.

Background The excimer laser ablation is currently widely used primarily to correct refractive errors by altering the anterior curvature of the cornea.

Lateral and anterior curvature (that is, laterally and anteriorly convex) and flat deltoid plane represent the ancestral hominoid condition, as present in Proconsul,and these characters are present also in Sivapithecus.
