20080312738 | Multifocal Iol - Intraocular lens consisting of a centrally located lens part with supporting parts (haptics) on either side. According to the invention one supporting part is non-deformable and another supporting part, located approximately opposite said supporting part, is deformable. In this way it is achieved that when the ciliary cell contracts the reduction in the space therein is used for moving the centre of the lens part. By arranging the transition between distance and near part in a multifocal lens on said centre, switching from the distance part to the near part can be obtained for the user in an almost natural way. | 12-18-2008 |
20090023879 | HIGH REFRACTIVE INDEX MONOMERS AND (CO)POLYMERS PREPARED THEREFROM - The present invention relates to high refractive index monomers according to formula (I) and (co)polymers comprising such high refractive index monomers.

20140067060 | OPHTHALMIC LENS HAVING ENHANCED OPTICAL BLENDING ZONE - An intraocular lens with a lens comprises a main lens part having a main lens surface and a main optical axis defining radial, tangential and axial directions; and a recessed part having a recess surface and extending between said main optical axis and a circumference of said lens, the recessed part comprising a secondary lens part with a secondary lens surface having a positive relative optical power with respect to an optical power of said main lens surface. The main lens surface extends in an outward radial direction towards a main lens outer circumference section remote from said the optical axis. The main lens outer circumference section and the main lens surface define an imaginary main lens outer circumference section that would have at least partially provided a main lens outer circumference together with the main lens outer circumference section in case the recessed part would have been absent; and an imaginary main lens surface section that would have been part of the main lens surface in case said recessed part would have been absent, the recess surface being recessed with respect to the imaginary main lens surface section. The recessed part extends in an outward radial direction to an outer recess boundary remote from said main optical axis, the outer recess boundary extending along or beyond said imaginary main lens outer circumference section as seen in an outward radial direction. | 03-06-2014 |
20140172091 | OPHTHALMIC LENS WITH OPTICAL SECTORS - An ophthalmic lens comprising a main lens part, a recessed part, an optical centre, and an optical axis through the optical centre, the main lens part having at least one boundary with the recessed part, the main lens part having an optical power of between about −20 to about +35 dioptre, the recessed part positioned at a distance of less than 2 mm from the optical centre and including a near part having a relative dioptre of about +1.0 to about +5.0 with respect to the optical power of the main lens part, the boundary or boundaries of the recessed lens part with the main lens part form a blending part or blending parts, are shaped to refract light away from the optical axis, and have a curvature resulting in a loss of light, within a circle with a diameter of 4 mm around the optical centre, of less than about 15%. | 06-19-2014 |
20140243972 | Intraocular lens - Intraocular lens for insertion into the human eye includes an optic having a posterior surface for facing towards the posterior chamber of the human eye; an anterior surface for facing away from the posterior chamber of the human eye, the anterior surface being at least substantially convex; a main lens formed by corresponding surface sections of the anterior and posterior surfaces, the main lens having an optical axis and a base optical power; and an additional surface section at a distance from the optical axis, the additional surface section including at least one additional section part providing for an optical power different from the base optical power. The posterior surface is substantially flat or at least substantially concave, and includes a substantially flat or at least substantially concave main posterior surface section, the main lens being formed by the anterior surface and the main posterior surface section. | 08-28-2014 |
