Abstract
Provided is a production device for producing an intraocular lens blank, with a first mold half, which has an outer ring, and a second mold half, which have a spacing state, in which the second mold half is arranged outside the outer ring, and a proximity state, in which the second mold half is clamped in the outer ring as a result of inserting the second mold half in an inserting direction, wherein the first mold half has a central region of the first mold half and the second mold half has a central region of the second mold half, wherein the second mold half has a bellows, which extends fully circumferentially around the central region of the second mold half in a circumferential direction with respect to an optical axis of the optical body and has a first bellows portion and a second bellows portion, which is arranged directly outside the first bellows portion in a radial direction with respect to the optical axis and, in the spacing state, forms with the first bellows portion a first angle (α), which is smaller than 180°, and, in the proximity state, forms with the first bellows portion a second angle (β), which is smaller than the first angle.
