Abstract: A sealing device for use inside a capsular bag after the natural lens has been removed comprises a plug part adapted to seal a rhexis in a capsular bag, thus preventing displacement through the rhexis of a lens-forming liquid material injected through the rhexis and adapted to replace the natural lens and form an intraocular lens implant. The plug part has a slightly larger area than the capsulorhexis and is made of a deformable polymer. The sealing device further comprises a removable adjusting means connected to the plug part, the adjusting means protruding anteriorly from an outer surface of the plug part and being capable of positioning the plug part to a desired location.

Abstract: An intraocular lens for providing a subject with vision at various distances includes an optic having a first surface with a first shape, an opposing second surface with a second shape, a multifocal refractive profile, and one or more diffractive portions. The optic may include at least one multifocal diffractive profile. In some embodiments, multifocal diffractive and the multifocal refractive profiles are disposed on different, distinct, or non-overlapping portions or apertures of the optic. Alternatively, portions of the multifocal diffractive profiles and the multifocal refractive profiles may overlap within a common aperture or zone of the optic.

Abstract: The present invention provides improved ophthalmic lenses and methods for their design and use. Monofocal and multifocal diffractive ophthalmic lenses having reduced light scatter, improved light energy distribution properties, and/or other improvements in optical performance are provided. These properties are provided, at least in part, by the diffractive profiles of the invention, often having subtlety shaped echelettes with appropriately curving profiles. Smooth diffractive profiles may be used reduce light scatter. Diffractive profiles may be configured to limit the light energy in certain selected orders, thereby improving viewing quality and mitigating unwanted effects such as dysphotopsia. Diffractive profiles of may additionally or alternatively vary the light energy distributed between individual echelettes, providing additional advantages in various viewing situations.

Abstract: An intraocular lens for providing accommodative vision to a subject includes a frame disposed about an optical axis, a first optical element, a second optical element, and a connecting element operably coupling the frame to the optical elements. The frame comprises an anterior frame element and a posterior frame element. The connecting element is configured to convert a first displacement between the frame elements in a direction that is substantially parallel to the optical axis into a second displacement between the optical elements that is substantially perpendicular to the optical axis. The second displacement may be translational and/or rotation. In some embodiments, the optical elements are two varifocal lenses.

Abstract: The present invention is in the field of ophthalmic surgery and relates to a method for the prevention of capsular opacification, especially after extraction of the natural lens from the lens capsule of the eye. Particular methods disclosed include replacing the natural lens with a capsule filling implant comprising an injectable material and injecting an agent capable of inhibiting the proliferation of lens epithelial cells, migration of lens epithelial cells, and/or production of extra-cellular matrix by lens epithelial cells into a space between the inserted capsule filling implant and the lens capsule using an instrument having a hydrophobic outer surface such that the composition reaches a germinative zone of the capsular bag.

Abstract: The present invention provides improved ophthalmic lenses and methods for their design and use. Monofocal and multifocal diffractive ophthalmic lenses having reduced light scatter and/or improved light energy distribution properties are provided. These properties are provided by the diffractive profiles of the invention, often having subtlely shaped echelettes with appropriately curving profiles. Light scatter may be generated by the sharp corners associated with vertical steps between adjacent conventional diffractive echelettes. Smooth diffractive profiles of the invention reduce light scatter. Light energy directed towards non-viewing diffractive orders may have a unwanted effects on vision quality. Diffractive profiles of the invention may limit the light energy in certain, selected orders, thereby improving viewing quality and mitigating unwanted effects such as dysphotopsia.

Abstract: An intraocular correction lens has at least one aspheric surface which when its aberrations are expressed as a linear combination of polynomial terms, is capable of, in combination with a lens in the capsular bag of an eye, reducing similar such aberration terms obtained in a wavefront having passed the cornea, thereby obtaining an eye sufficiently free from aberrations.
