An ophthalmological device for processing a curved treatment face in eye tissue comprises a scanner system with a plurality of scan axes configured to move the focal spot to target locations in the eye tissue. A circuit is configured control the scanner system to move the focal spot to target locations along a processing path, defined by treatment control data, to process the curved treatment face in the eye tissue. The circuit is further configured to perform a feasibility check, using the treatment control data and scan capabilities of the scanner system, defined by scan performance characteristics of each particular scan axis. In case the feasibility check indicates that moving the focal spot along the processing path exceeds the scan capabilities of the scanner system, the circuit adjusts the treatment control data.

An ophthalmic device for treating eye tissue using laser pulses comprises a projection optical unit for focused projection of the laser pulses and a scanning device, with a movable mirror, arranged downstream from the projection optical unit, for deflecting the laser pulses projected by the projection optical unit in at least one deflection direction. The ophthalmic device moreover comprises an optical correction element arranged downstream of the scanning device, which correction element is configured to image, in a focused manner, the laser pulses deflected by the scanning device on an intended treatment area in the eye tissue. The optical correction element renders it possible to therefore correct image field curvatures caused by the scanning device arranged downstream from the projection optical unit and, for example, image the deflected laser pulses in focus onto a plane.

For processing eye tissue using a pulsed laser beam (L), an ophthalmological device includes a projection optical unit for the focused projection of the laser beam (L) into the eye tissue, and a scanner system upstream of the projection optical unit for the beam-deflecting scanning of the eye tissue with the laser beam (L) in a scanning movement (s′) performed over a scanning angle along a scanning line(s). The projection optical unit is tilted about an axis of rotation (q) running perpendicularly to a plane defined by the scanning line(s) and the optical axis (o) of the projection optical unit, the tilting of the projection optical unit tilting the scanning line (s) in said plane. Tilting of the scanning line(s) enables a displacement—dependent on the scanning angle—of the focus of the laser pulses projected into the eye tissue without vertical displacement of the projection optical unit.

An OCT imaging system may include an OCT light source operable to emit an OCT light beam, and a beam splitter operable to split the OCT light beam into a sample beam, transferred to a sample arm waveguide, and a reference beam, transferred to a reference arm waveguide. The sample arm waveguide and the reference arm waveguide may be coupled together within a cladding, wherein the cladding improves a calibration of a generated OCT image by fixing axial movement of the sample arm and reference arm waveguides relative to one another. By routing long reference and sample arm waveguide fibers together in the OCT system using a sheath/cladding, OCT image offset due to asymmetrical fiber stretching can be minimized or eliminated.

A method of macular disease treatment (500) may include introducing nanocapsules into a body of a patient (502). The nanocapsules may be introduced such that the nanocapsules circulate through at least a portion of a body of the patient. A therapeutic substance and a colorant may be encapsulated into the nanocapsules. After a portion of the nanocapsules enters choroidal neovessels of an eye of the patient, the method may include emitting a pulsed laser radiation through a pupil of the eye (504). Additionally, after a portion of the nanocapsules enters choroidal neovessels of an eye of the patient, the method may include heating the portion of the nanocapsules present in the eye (506) such that at least a portion of the nanocapsules transfer phase and release the therapeutic substance.

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.
