INTRAOCULAR LENS AND EYE TREATMENT METHOD Russian patent published in 2024 - IPC A61F2/16 

FIELD: medicine.

SUBSTANCE: intraocular lens for providing depth of field comprises: an optical zone; first peripheral area; and a second peripheral region; wherein the first light rays incident on the front optical surface pass through the optical zone to form an image on the retina when the intraocular lens is implanted in the eye; and wherein the second light rays incident on the front surface of the active diaphragm are scattered along the intraocular lens towards and along the retina such that the image has a depth of field, and wherein said active diaphragm further reduces monochromatic and chromatic aberrations in the image. Method for correcting eye aberrations, comprising a step of implanting an eye implant into the eye.

EFFECT: use of this group of inventions provides correction of defocusing and astigmatism, reduces monochromatic and chromatic aberrations of higher order and provides increased depth of field in order to improve quality of vision.
