    Abstract: A phacoemulsification system, comprising: a handpiece comprising a piezoelectric element and a needle, the needle configured to be inserted into an eye and to be vibrated by the piezoelectric element to emulsify a lens of the eye; an irrigation module configured to supply a flow of irrigation fluid into the eye; an aspiration module configured for removing material from the eye; circuitry configured to determine whether at least a distal tip of the needle is inside the eye or is outside the eye; and a processor, which is configured to receive a determination from the circuitry as to whether the distal tip of the needle is inside or outside the eye, and to control operation of at least the irrigation module according to the determination.

    Abstract: A system for therapy of the eye by treating tissue with therapeutic radiation using nonlinear interaction. A laser device is provided, which delivers the therapeutic radiation. The therapeutic radiation is focussed by a focussing device in an image field, and xy scanners and z scanners shift the focus laterally and longitudinally within a treatment volume. The therapeutic radiation is either a second short pulse radiation or a first short pulse radiation, each of which have a spectral centroid within a wavelength range defined by the short pulse properties. The system is particularly corrected with regard to longitudinal chromatic aberrations and lateral chromatic aberrations such that the spectral characteristic curves of the two aberrations each have a local extreme within the wavelength ranges, and a certain tolerance within the wavelength ranges is not exceeded, therefore the characteristic curves are very shallow.

    Abstract: A device insertion tool can include a body and a light redirecting structure. The body can extend along a central longitudinal axis between forward and aft ends. The body can include a device mount portion at the forward end to hold an optic and a handle portion at the aft end configured to be held. The body can be inserted into an anterior chamber of the eye with the optic mounted on the device mount portion at the forward end. The light redirecting structure can be engaged with the body between the forward and aft ends. The light redirecting structure can be one of at least one mirror and at least one prism. The light redirecting structure can be directed at the forward end and can be configured to redirect light traveling from the forward end toward the aft end transverse to the central longitudinal axis.
