Abstract
The present technology relates to accommodating intraocular lenses (AIOLs) and methods of manufacturing the same. In many of the embodiments disclosed herein, the AIOLs include an adjustable lens structure and a fixed lens configured to be removably coupled to the accommodating lens structure. The adjustable lens structure can include a base defining an adjustable lens and a lens-receiving area configured to receive the fixed lens. The adjustable lens can have a dynamically adjustable range of optical powers and/ or depths of field. The fixed lens can have a fixed optical power and/or depth of field. The base of the AIOL can be a unitary body formed using, e.g., rotational molding.
Claims31
An accommodating intraocular lens assembly, comprising:
- a base including an adjustable power lens having an optical power and an optical axis, wherein the base is a single-piece component composed of a polymer,
- wherein the optical power of the adjustable power lens changes dynamically along an optical axis of the adjustable power lens in reaction to a radial force on the base in a direction non-parallel to the optical axis;
- and
- a fixed power lens configured to be removably coupled to the base.
A method for manufacturing an adjustable intraocular lens, the method comprising:
- at least partially filling a mold configured to form a base of the adjustable intraocular lens with a polymer;
- rotating the mold about one or more axes for a predetermined amount of time;
- and
- after the predetermined amount of time has passed, removing the base from mold.
An accommodating intraocular lens assembly, comprising:
- a base including a bellows region and a lens region, wherein—
- the bellows region defines an outer fluid reservoir and is a single-piece component composed of a polymer,
- the lens region includes a first optical portion coupled to the bellows region at a first seam and a second optical portion coupled to the bellows region at a second seam to define an inner fluid volume, and
- the first and second optical portions and the inner fluid volume together define an adjustable power lens having an optical power, wherein the base is configured to dynamically change the optical power in reaction to a force on the base;
- and
- a fixed power lens configured to be removably coupled to the base.
A method for manufacturing an adjustable intraocular lens, the method comprising:
- at least partially filling a mold configured to form at least a bellows region of a base of the adjustable intraocular lens with a polymer;
- rotating the mold about one or more axes for a predetermined amount of time;
- after the predetermined amount of time has passed, removing the bellows region from mold;
- and
- coupling a lens portion of the base to the bellows region.
