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 d...
