OPHTHALMIC LENSES CONTAINING ELEMENTARY LENSES FOR PREVENTION AND/OR SLOWING DOWN OF MYOPIA PROGRESSION Russian patent published in 2023 - IPC A61F9/00 A61F2/14 G02C7/02 G02C7/04 G02C7/08 

FIELD: medicine.

SUBSTANCE: ophthalmic lens for at least one of slowing down, containment, or prevention of myopia progression contains: a front convex surface; a rear concave surface; and an optical area including main far vision correction areas of the base sphere and elementary lenses with an additional optical force, which are myopic defocusing areas distributed between main far vision correction areas of the base sphere and adjacently to them. Main correction areas of the base sphere are made with the possibility of creation of a wave front, which is focused at one point along the main optical axis of the ophthalmic lens and on the eye retina. Elementary lenses with an additional optical force are made with the possibility of creation of non-coaxial wave fronts, which are focused in front of the retina along their own optical axis, which differs from the main optical axis. A combination of elementary lenses and main far vision correction areas is located with the possibility of provision of clear vision and myopic defocusing for all retinal areas. The ophthalmic lens is selected from a group consisting of glasses lenses, intraocular lenses, and corneal implanted/applied lenses.

EFFECT: use of the invention allows for an increase in the efficiency of treatment with enhancing impact of myopic defocusing, without affecting the image quality in the fovea.
