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 ...

NCLE Practice base curve - refers to the radius of curvature of the central posterior surface of the lens. It may be expressed in diopters of surface power (D) or in millimeters (mm) of radius or curvature. optical zone - the chord diameter over which the base curve extends on the posterior surface of the contact lens, described in millimeters secondary or intermediate curves - lies between the base curve and the peripheral curve on the posterior lens surface, usually 0.70mm to 1.50mm f...

NCLE Advanced Certification Exam With Correct Answers 2023 update 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 desi...

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. - Answer 1.
