NCLE Optometry Exam Comprehensive optic zone - the central portion of a contact lens which contains the refractive power and generally corresponds to the central corneal cap posterior apecal radius - this term is generally used in reference to spin-cast soft lenses. the curvature of the posterior surface of the lens changes with the refractive power. the radius of curvature is measured at the apex of the posterior surface. steeper base curve - occurs when the posterior radius of curvat...
