摘要：
An intraocular lens (IOL) (1), comprising a lens (3) with - a main lens part (4) having a surface, said main lens part (4) having an optical power of between about - 20 and approximately + 35 diopters； - an optical center, and an optical axis (R) through said optical center； - a recessed part (7, 8) having a surface that is recessed with respect to said surface of said main lens part (4), said recessed part (4) having at least one limit with said main lens part, being said recessed portion (7, 8) located at a distance of less than 2 mm from said optical center and comprising a fence portion having a relative diopter of about + 1.0 to about + 5.0 with respect to the optical power of said main lens part (4), said boundary or limits of said lens part recessed with said main lens part a combination part or combination parts (10, 11) formed to refract the light away from said optical axis when said IOL (1) is illuminated by means of a collimation lens and placed in an ISO model eye having an aperture of 4 mm in diameter, said part being recessed on two sides delimited by semimeridians that run from dic or optical center, the recessed part being thus formed as a meridian zone, said combination parts being on said two sides within semimeridians enclosing an angle (γ) greater than 1 degree and less than 35 degrees, and having a form of said combination parts an S-shaped curve having a slope or first derivative in a more inclined part in a central range of the combination part 1.6 mm from said optical center of less than 0.41.Una lente intraocular (LIO) (1), que comprende una lente (3) con - una parte de lente principal (4) que tiene una superficie, teniendo dicha parte de lente principal (4) una potencia óptica de entre aproximadamente - 20 y aproximadamente + 35 dioptrías； - un centro óptico, y un eje óptico (R) a través de dicho centro óptico； - una parte rebajada (7, 8) que tiene una superficie que está rebajada con respecto a dicha superficie de dicha parte de lente pri
