NCLE Advanced Certification 2024 Exam Correctly Answered The answer is D. The posterior optical zone will directly affect the lens to cornea relationship of a rigid gas permeable lens. If the posterior optical zone is steepened, it will increase the sagittal depth. If it is flattened, it will decrease the sagittal depth. Changing the power, which is accomplished by changing the anterior optical zone, will not affect the sagittal depth of the lens, nor will changing its edge design. - Answe...

optic zone -Answer the central portion of a contact lens which contains the refractive power and generally corresponds to the central corneal cap posterior apecal radius -Answer 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 -Answer occurs when the posterior radius of curvature is decreased (i.e...
