Paradoxical optical power increase of a deformable lens by equatorial stretching
Abbreviated Journal Title
Ann. Ophthalmol. Glaucoma
Yertical scanning interference microscope measurements of the mean radius of curvature (ROC) of bath surfaces of constant-volume deformable, water-filled lenses were obtained before and during small displacement stepped equatorial stretching in the plane perpendicular to the optical axis, Each lens demonstrated a marked decrease of the ROC at its optical center: However: the ROC increased in a region halfway between the center and the outer diameter of the lens, This is indicative of central steepening with peripheral flattening This is contrary to the assumption that stretching of the equator of a deformable lens will only reduce its optical power.
