Optic Zone - Central portion of a contact lens which contains the refractive power 
(generally corresponds to the corneal cap) 
Posterior Apecal Radius - Spin-cast soft lenses. (Curvature of posterior surface 
changes with refractive power. Measured at apex of posterior surface) 
Steeper Base Curve - As the Posterior radius of curvature is decreased the base 
curve becomes: (i.e. 8.4-8.1) 
Flatter Base Curve - As the Posterior radius of curvature is increased the base 
curve becomes: (i.e. 8...

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. correct answers 1. The sagittal depth of a rigid gas permeable cont...
