  • INTRAOCULAR LENS PLATFORM HAVING IMPROVED HAPTIC FORCE DISTRIBUTION
    Publication number: 20220168093
    Abstract: An ophthalmic lens includes an optic comprising an anterior surface, a posterior surface, and an optic edge extending between the anterior surface and the posterior surface, the optic having an optical axis. The ophthalmic lens further includes a plurality of haptics extending from a periphery of the optic, each of the plurality of haptics including a gusset region, a distal region, and an elbow region connecting the gusset region to the distal region. The gusset region of each of the plurality of haptics extends from the periphery of the optic and spans a portion of the periphery of the optic. In addition, the gusset region of each of the plurality of haptics monotonically increases in thickness with increased distance from the periphery of the optic, while the distal region of each of the plurality of haptics monotonically decreases in thickness with increased distance from the elbow region.
