Unique Parameters and Lens Features: The Jeraly lenses are fit based on prolate or oblate corneas. The Jeraly lens is available with toric and multi-focal features with reverse geometry corneal curves to optimize apical clearance. Standard fitting sets have a simplified adjustment feature such that every diopter of base curve change is equal to 100 microns of sagittal depth change. Precision fitting options include limbal curve adjustments in increments of 50 microns and scleral landing zone adjustments in increments of 50 microns. Lenses are designed with toric haptic curves of 100 microns which are adjustable by 50 microns in either direction for better centration and stability. The scleral landing curves are laser etched at 0° and 180° to help identify necessary cylindrical corrections. Specified quadrant curves are available in every zone of the design.
