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 d...

How does refractive power of a lens change if its radius of curvature decreases? - The power increases How does refractive power of a lens change if its radius of curvature increases? - The power decreases What is radius of curvature in case of a lens? - Flattener lens= larger radius of curvature. More rounded lens=lesser radius of curvature. How does refractive power of a lens change if its index of refraction increases? - Refractive power will increase Calculate the refractive power o...

What is the Secondary/intermediate curve? : 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? : 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 the peripher...

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 lens can be altered ...
