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. 8.4 to 8.1 mm) flatter base curve - ANSWER-occurs when the posterior radius of curvature is increased (i.e.8.1 to 8.4 mm) bicurve lens - A...

What is the Secondary/intermediate curve? - Answer The curve on the posterior side of the contact lense between the base curve and peripheral curve. Usually 0.7mm to 1.6mm flatter than the base curve radius. The width is affected by the OZ diameter and peripheral width. What is the peripheral curve? - Answer The outermost curve on the posterior side of the contact lens. It clears the flatter periphery and prevents lens impingement in the limbal areas What measurements effect the size of th...

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. The sagittal depth of a rigid gas permeable contact len...
