Secondary Intraocular Lens with Magnifying Coaxial Optical Portion
A secondary foldable intraocular lens, IOL, (2) is provided that is surgically implanted in addition to at least one primary IOL (1) in the patient's pseudo-phakic eye. The secondary IOL (2) is arranged optically coaxial to the primary IOL (1) focusing a combined image onto the retina (5) of the patient's eye (4) additionally magnifying at least a central part of the image of the primary IOL (1) projected onto the macula (6) of the retina (5). The secondary IOL (2) comprises one or more haptics (7) for fixing and stabilizing it within the sulcus ciliaris (8) of the patient's eye (4)and an optically active portion (9) designed to project the image through the primary IOL (1) onto the retina (5). The optically active portion (9) of the secondary IOL (2) comprises a central optical portion (10) and a peripheral optical portion (11) extending around the central optical portion (10), forming two different, but coaxially positioned lenses from one block. The central optical portion (10) is designed to form a positive lens providing additional refraction of minimum 5D, up to maximum 25D to the refraction provided by the peripheral optical portion (11) of the secondary IOL (2).
Micro-incision IOL and positioning of the IOL in the eye
An intraocular lens that is capable of being inserted through a micro-incision includes an optic having an anterior and a posterior surface and a plurality of projections extending from the anterior and posterior surfaces. The anterior and posterior surfaces include a recess. The optic is implanted such that a rim of the capsulorhexis is disposed in the recess such that the plurality of projections grip the capsular bag.
Intraocular lens having a specific, three-dimensionally curved haptic element
An intraocular lens is provided which includes a single optical part, a haptic element, which is coupled to the optical part, and an optical main axis, which penetrates a front face and a rear face of the optical part, the haptic element having a first haptic part, which is in the form of a first ring and extends around the optical part, and at least one second haptic part, which is in the form of a second ring and extends around the optical part and is elastically movable relative to the first haptic part, at least one of the two rings being uneven in the peripheral direction about the optical main axis, at least one of the two rings having exactly two ring valleys and exactly two ring hills.
Posterior chamber phakic intraocular lens
The present invention relates to a posterior chamber phakic intraocular lens (1) comprising a central optical part (2), a peripheral haptic part (3) having distal support elements (4) arranged for supporting the intraocular lens (1) on a ciliary zonule, elongated flexible footplates (5) mounted on the support elements (4), each having a distal lateral border (53) arranged for stabilizing the intraocular lens (1) into a ciliary body (98), and manipulation pockets (6) on a surface of the support elements (4), each being associated with one of the elongated flexible footplates (5).
