摘要:
An intraocular lens having a lens containing the main part of the lens having the main surface of the lens, as well as the main optical axis defining radial, tangential and axial directions, as well as the recessed part having the surface of the recess and extending between the main optical axis and the periphery of the said lens, wherein the recessed portion comprises a secondary lens portion having a secondary lens surface having a positive relative optical power with respect to the optical power of said main lens surface. The main surface of the lens extends in the outer radial direction to the outer circumference of the main lens, remote from the main optical axis. The outer circumference section of the main lens and the main surface of the lens define an imaginary section of the outer circumference of the main lens, which would at least partially create the outer circumference of the main lens together with the said section of the outer circumferential main lens, if the recessed part were absent, as well as an imaginary section the surface of the main lens, which would be part of said main surface of the lens if said recessed part were absent, said surface of the recess recessed relative to an imaginary section of the surface of the main lens. The recessed portion extends in the outer radial direction to the outer boundary of the recess remote from said main optical axis, wherein the outer boundary of the recess extends along or outside said imaginary section of the outerИнтраокулярная линза, имеющая линзу, содержащую основную часть линзы, имеющую основную поверхность линзы, а также главную оптическую ось, определяющую радиальное, тангенциальное и аксиальное направления, а также углубленную часть, имеющую поверхность углубления и продолжающуюся между упомянутой главной оптической осью и периферией упомянутой линзы, при этом углубленная часть содержит вторичную часть линзы, имеющую вторичную поверхность линзы, обладающую положительной относительной оптической си
