A newly filed patent (Publication Number: US20240008973A1) describes a lens designed for implantation into the human eye, featuring an optic made of transparent material with aspheric surfaces on both the anterior and posterior sides. The lens includes at least one haptic to secure it in place once implanted. The posterior surface of the optic has a unique biconic shape offset by aspheric perturbations, with specific parameters such as radius of curvature, conic constants, and ratios between them falling within defined ranges. Additionally, the lens is characterized by a radial power profile for wavefront at the exit pupil, with specific coefficients and thickness along the optical axis.

Furthermore, the patent details various claims related to the ratios of curvature, conic constants, and thickness of the lens, providing specific ranges for each parameter to ensure optimal performance. The lens is designed to have a meniscus shape with a convex anterior surface and a concave posterior surface, with precise measurements for the radius of curvature on both surfaces. The conic constants for the surfaces are also specified, with the anterior surface having a conic constant of 0 or -1.0. Overall, the patent outlines a meticulously designed lens for eye implantation, incorporating innovative features to enhance visual outcomes and patient comfort.
