The first successful contact lenses which were originally molded to conform to the shape of the cornea were known as - Scleral/Haptic lenses Corneal contact lenses: - are the most common design for rigid and gas permeable lenses. The majority of soft lenses fit today are: - semi-scleral A liquid coming in contact with a hydrophilic lens material with a relatively small wetting angle would be likely to: - spread evenly over its surface A contact lens with diameter larger than that of th...

optic zone -Answerthe central portion of a contact lens which contains the refractive power and generally corresponds to the central corneal cap posterior apecal radius -Answerthis 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 -Answeroccurs when the posterior radius of curvature is decreased (i.e...

NCLE Advanced Certification Exam Questions With Correct Answers Latest 2024 (GRADED) 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...
