NCLE Advanced Certification Exam 2024 with Complete Solutions NCLE Advanced Certification Exam 2024 with Complete Solutions NCLE Advanced Certification Exam 2024 with Complete SolutionsThe 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 accomplishe...

NCLE basic Exam Kit Questions with correct Answers 2023 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 ...
