Peripheral myopic defocus contacts

WebThe advanced design increases mid-peripheral steepening on the cornea. The zone is calculated to create high mid-peripheral plus and myopic defocus. It allows the hydraulic forces to flatten the central cornea and form a mid-peripheral ring that may be observed in a topography. This may be changed in 0.12 D steps. WebPurpose: To evaluate changes in the peripheral refraction (PR), visual quality, and accommodative lag with a novel soft radial refractive gradient (SRRG) experimental contact lens that produces peripheral myopic defocus.
