EYE LENS, IN PARTICULAR INTRAOCULAR LENS, HAVING A TORIC REFRACTIVE SURFACE PROFILE AND A HELIX WINDING AS A SURFACE STRUCTURE ON AN OPTICAL PART

摘要

The invention relates to an eye lens (1), comprising an optical part (2), which has a first optical side (4) and a second optical side (5) with respect to a direction of an optical principal axis (A) of the eye lens (1), a helix winding (6) being formed on at least one of the two sides (4, 5) as a surface structure, by means of which helix winding a refractive power of the eye lens (1) varies with respect to value in a circumferential direction about the principal axis (A). In addition to the helix winding (6), a toric refractive surface profile (7) is formed on at least one side (4, 5).
