Methods and apparatuses to increase intraocular lenses positional stability

A multi-piece IOL assembly is provided that includes a platform and an optic. The platform has an inner periphery surrounding an inner zone of the platform. The optic has an optical zone, an outer periphery and a retention mechanism disposed on the outer periphery. The optic is configured to be disposed in the inner zone of the platform and to extend to a location between the inner periphery and the outer periphery of the platform to be secured to the platform at the location. The platform can be secured to an inner periphery of the eye or can be formed into a natural lens by cutting the lens using a laser or other energy source.

High definition and extended depth of field intraocular lens
11547554 · 2023-01-10 · ·

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.

Methods of molding intraocular lenses

Intraocular implants and methods of making intraocular implants are disclosed. The intraocular implant can include a mask adapted to increase depth of focus. The method of manufacturing the implant can include filling an annular mask-forming trough with an opaque mask material and adding an optically transmissive optic material over the opaque mask material.

Modular IOL design

A modular intraocular lens (IOL) with a ring configured to prevent glare artifacts. The ring includes a flange on the posterior rim, in which an anterior surface on the flange has a first profile and a posterior surface of the flange has a second profile non-parallel with the first profile. Non-parallel surfaces of the flange can be configured to defocus light transmitted at off-axis angles through an optic and the flange.

OPHTHALMIC PROSTHETIC TO TREAT NEGATIVE AND POSITIVE DYSPHOTOPSIA
20230054347 · 2023-02-23 ·

An ophthalmic prosthetic and method for correcting negative and positive dysphotopsia. The ophthalmic prosthetic comprises a peripheral light blocking implant member adapted to locate in a gap between an iris and an intraocular implant lens. The gap is between the anterior surface of the lens and the posterior portion of the iris. An opacity of the peripheral light blocking implant member is selectively positioned to block passage of light.

OPHTHALMIC PINHOLE PROSTHETIC WITH SURFACE MODIFICATIONS AND METHOD OF FABRICATION
20230058505 · 2023-02-23 ·

An ophthalmic pinhole prosthetic and a method of fabricating the same. The ophthalmic pinhole prosthetic comprises an annular portion, an inner perimeter, and an interior light transmitting portion. The annular portion may be optically opaque or at least partially optically opaque. The inner perimeter may include surface modifications configured to reduce or substantially eliminate diffraction of light compared to an ophthalmic pinhole prosthetic without the surface modifications. The interior light transmitting portion may be located within the annular portion and function to allow passage of light to interact with a retina.
