NCLE Advanced Certification Exam with COMPLETE SOLUTION | 459 Questions with 100% Correct Answers 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...

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. - 1.

base curve - Answer 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 - Answer the chord diameter over which the base curve extends on the posterior surface of the contact lens, described in millimeters secondary or intermediate curves - Answer lies between the base curve and the peripheral curve on the posterior lens surface, usually 0.70m...
