A method is disclosed for controlling a laser device for a laser-induced refractive index change (URIC) of a polymer structure. The laser device is controlled by a control device such that it emits pulsed laser pulses in a shot sequence in a preset pattern into the polymer structure. The laser pulses are emitted with preset irradiation parameters for refractive index change of the polymer structure, wherein for adjusting an order of magnitude of the refractive index change, a spatial pulse distance of the laser pulses in the polymer structure is adapted and the further irradiation parameters are kept within respective preset irradiation parameter ranges.

The invention relates to a method for producing an intraocular lens, including the steps of providing a container which is transparent to electromagnetic radiation and in which a liquid that is curable by the electromagnetic radiation is arranged; irradiating the liquid with a set of images formed by the electromagnetic radiation, which each depict an intraocular lens, with each of the images of the set being radiated into the liquid at a different angle of incidence with respect to a reference plane that extends through the liquid, as a result of which the liquid is cured and the cured liquid forms the intraocular lens, an actuator, a solar module and/or a sensor being arranged in the liquid and the intraocular lens being formed around the actuator, the solar module and/or the sensor.

A method for producing an accommodative intraocular lens includes providing first and second components and a support body with an interior space and open to the top, fastening the first component to the support body, generating pressure which is higher in the exterior space than in the interior space such that the first component deforms downward, producing an adhesive surface on the upper side of the first component and/or on the second component, applying a liquid to the first component from above into the latter's downwardly deformed region, the liquid at no time contacting the adhesive surface, fastening the second component to the first component with the adhesive surface, as a result of which the accommodative intraocular lens is formed and the liquid is encapsulated with the first component and the second component in a cavity arranged in the interior of the intraocular lens.

A blazed diffractive optical element includes: a blazed diffraction grating pair that includes a first blazed member and a second blazed member and functions as a diffraction grating with the first blazed member and the second blazed member; and an interlayer that is positioned between the first blazed member and the second blazed member, in which in a case where a refractive index of the first blazed member is represented by Na, a refractive index of the interlayer is represented by N, and a refractive index of the second blazed member is represented by Nb, a magnitude relationship of Na>N>Nb is satisfied.

In certain embodiments, a system for making an implant for an eye comprises a laser, a camera, and a computer. The laser emits a laser beam to shape a material. The camera generates one or more images to monitor shaping of the material. The computer stores a pattern for the implant, which is designed to provide refractive treatment for the eye; sends instructions to the laser to control the laser beam to shape the material according to the pattern; assesses the images from the camera according to the pattern; and adjusts the instructions in response to the images.

Non-invasive Ocular Drug Delivery Insert Technology. The invention concerns an ocular insert which is a new biocompatible polymer-based controlled drug delivery system (CDDS) applicable to a variety of drugs and other compounds for the treatment of different ocular pathologies. This ocular insert allows releasing of at least one drug under suitable concentration levels during suitable periods of time. The device may be inserted in the lower or upper fornix conjunctiva, in a non-invasive way, meaning that the patient will be able to place the device himself, without intervention of medical specialized staff. The insert of the invention will release the drug in such a controlled rate that will allow the drug release up to 300 days by either a “Fickian” or a linear profile according to the intend purpose or pathology. The insert can be prepared with different shapes (spherical or spherical dome) and/or architectures (monolithic/layered either with or without a drug core) allowing the incorporation of at least one drug which can be released at different rates. The size, shape and design of the insert is adjusted in order to tune the drug(s) delivery profile(s) and to inhibit the risk of displacement or expulsion.

An intraocular lens (IOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.
