摘要:
A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

Prosthetic capsular devices (e.g., bag, bowl, housing, structure, cage, frame) include technology devices such as a computer, virtual reality device, display device, WiFi/internet access device, image receiving device, biometric sensor device, game device, image viewers or senders, GPSs, e-mail devices, combinations thereof, and/or the like. The technology devices can be used in combination with an intraocular lens. The output from the technology device(s) can be fed to the retina of the user to provide a visual image, can be otherwise connected to the user, and/or can be used to control the properties of the intraocular lens or of the prosthetic capsular device. Wearable technology that provides biometric data, such as blood glucose levels, body temperature, electrolyte balance, heart rate, EKG, EEG, intraocular pressure, sensing ciliary muscle contraction for accommodation stimulus, dynamic pupil change and retinal prostheses, combinations thereof, and the like can assist in technology-assisted health care functions.
摘要:
A prosthetic capsular device configured to be inserted in an eye includes a housing structure and a ring structure. The housing structure includes a first side, a second side opposite the first side, a third side, a fourth side opposite the third side, a posterior side including a refractive surface, an anterior side opposite the posterior side, and a longitudinal axis. The first side, the second side, the third side, the fourth side, the posterior side, and the anterior side at least partially define a cavity configured to contain an intraocular device (e.g., an IOL). The anterior side includes an opening. The ring structure includes a ring structure portion extending radially outward from proximate one of an end of the first side and an end of the second side.
摘要:
The present disclosure provides intraocular artificial lenses having a variable optical strength and methods of treating an eye disorder, such as presbyopia, using same. In some embodiments, the intraocular artificial lens comprises two optical elements that are moveable along the optical axis in relation to each other, for example in response to the accommodative process of the eye.
摘要:
A multicomponent intraocular lens (201) implantable in an optical system of a human eye, comprising: a base component (220) and a front component (210), the front component comprising an attachment tab (212) which extends from a circumferential side of the optical portion (211) of the front component and engages the flange for attaching the front component to the base component, wherein the attachment tab of the front component comprises a resilient projection that protrudes away from the optical portion beyond the flange (228), wherein a portion of the resilient projection (212) is located at a non-overlapping position with respect to the haptic (222) of the base component in a circumferential direction around the optical portions, wherein the portion of the resilient projection has a back surface (213) which is located backwards from a front surface (230) of the haptic of the base component in the thickness direction of the base component.
摘要:
A capsular ring for insertion into a capsular bag of a patient's eye includes an anterior ring defining a first opening and having a first cross-sectional width and a posterior ring defining a second opening and having a second cross-sectional width. A diameter of the first opening is greater than a diameter of the second opening, and the second cross-sectional width is greater that the first cross-sectional width. The capsular ring further includes a sidewall connecting the first ring and the second ring, the sidewall comprising a plurality of orifices spaced circumferentially around the sidewall.
摘要:
Generally, an intraocular implant and methods for treating an ocular condition. As to certain embodiments, an intraocular biocompatible biodegradable implant (11) which can provide a biocompatible biodegradable material in the form of a flexible membrane (12) containing an active agent (24) which implanted between an intraocular lens (8) and the surface of the posterior capsule (5) of the eye (1)(4) inhibits migration of residual lens epithelial cells after cataract surgery by providing structural or pharmaceutical barriers to reduce posterior capsule (5) opacification of the eye (1)(4).
摘要:
Disclosed herein is an implantable capsule expander device for insertion within a lens capsule of an eye of a patient. The device comprises an arcuate center portion including first and second rims and having a first height, an outermost peripheral portion including a second height that is less than the first height, and a receiving portion formed between the first and second rims. The center portion and the outermost peripheral portion are configured to stabilize the capsule expander device within the lens capsule and to expand the lens capsule. The receiving portion is sized to receive an artificial intraocular lens.
