Method for patterned plasma-mediated modification of the crystalline lens

A method of treating a lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern of the light beam, delivering the treatment pattern to the lens of a patient's eye to create a plurality of cuts in the lens in the form of the treatment pattern to break the lens up into a plurality of pieces, and removing the lens pieces from the patient's eye. The lens pieces can then be mechanically removed. The light beam can be used to create larger segmenting cuts into the lens, as well as smaller softening cuts that soften the lens for easier removal.

An intraocular lens, wherein an outer periphery of an optic portion has a peripheral surface, and a radially inner portion of a peripheral portion of the IOL has an inner surface, wherein the peripheral surface is directly adjacent to the inner surface, and wherein the peripheral surface does not directly extend (coupled to or integrally formed therewith) from the inner surface, and wherein the peripheral surface and the inner surface are configured so that the peripheral portion is stabilized in at least one of, and optionally both of, the proximal and distal directions relative to the optic portion.

PROGRESSIVE POWER INTRAOCULAR LENS, AND METHODS OF USE AND MANUFACTURE

Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.

High definition and extended depth of field intraocular lens
10765510 · 2020-09-08 · ·

A virtual aperture integrated into an intraocular lens is disclosed. Optical rays which intersect the virtual aperture are widely scattered across the retina causing the light to be virtually prevented from reaching detectable levels on the retina. The use of the virtual aperture helps remove monochromatic and chromatic aberrations yielding high-definition retinal images. For a given definition of acceptable vision, the depth of field is increased over a larger diameter optical zone. In addition, thinner intraocular lenses can be produced since the optical zone can have a smaller diameter. This in turn allows smaller corneal incisions and easier implantation surgery.

A method improves depth of focus in a first eye only by adding a higher order aberration (HOA) to the first eye by adding a monofocal optical device to the first eye. The method may also correct a spherical aberration in a second eye by inserting a monofocal aspheric IOL. The HOA added to the first eye may be selected from the group consisting of spherical, trefoil and coma. Additionally, the monofocal optical device inserted into the first eye may comprise a monofocal aspheric IOL that adds spherical aberration to the first eye. The optical device inserted into the first eye may comprise a 20 D monofocal aspheric IOL that adds 0.4 m of spherical aberration to the first eye at 6 mm entrance pupil and adds 0.1 m of spherical aberration to the first eye at 4 mm entrance pupil.
