A device and method for the pre-display of a spot pattern to be applied for a laser treatment of the eye. The spot patterns to be applied are displayed to the operator in advance with the aid of a target beam. The device for the pre-display of a spot pattern to be applied for a laser treatment of the eye includes a laser system and a scanning system for generating a target beam. Here, the laser system and the scanning system for generating the target beam are formed to generate one or more lines which overlie all the spots of the spot pattern of a planned laser treatment. The device and method are suitable for laser treatment of the retina, the trabecular meshwork as well as other regions. Here, it is irrelevant whether what the laser treatment to be applied is.

A device for superimposing parameters and/or image data in the stereoscopic observation path of ophthalmological devices relates to an apparatus for reflecting relevant parameters and/or image data into the stereoscopic observation beam path of ophthalmic devices, for example for therapeutic laser treatments of an eye. The device includes an additional micro-display, which is connected to the control unit, and a beam deflection element for reflecting the parameters and/or image data shown on the micro-display into the stereoscopic observation beam path, which are for example arranged in the parallel beam path. Even though the apparatus is intended for ophthalmic devices for therapeutic laser treatment in the eye, it can also be used, in principle, for ophthalmic devices for examination, diagnosis and surgical interventions.

A method for a minimally invasive, cell-selective laser therapy on the eye. The method, based on a short-pulse laser system, allows for different selective types of therapy on the eye. The method is based on a frequency-doubled, continuously working solid-state laser including a pump source and a control unit. The control unit regulates the pump source such that the solid-state laser emits individual pulses with pulse lengths ranging from 50 ns to continuous, wherein pulse lengths ranging from 50 ns to 50 &#x3bc;s are provided for selective therapies and pulse lengths ranging from 50 &#x3bc;s to continuous are provided for coagulative or stimulating therapies, in particular in the range from 1 ms to 500 ms. The proposed method enables a selective treatment of melanin-containing cells in the different areas of the eye via the targeted control of the pump source.

A laser therapy device includes: a solid-state laser for a CW operation and including a pump source; and a controller for generating at least one first pulse of the laser in a first-pulse operation, the controller switching on the pump source to a pump power level S1 at least once during the first-pulse operation. A rise time E, after which the pump power level S1 of the pump source is attainable and starting from the time the pump source is switched on, is in a range of 50 ns to 350 ns.

A method for marking coagulation sites on a retina by application of a light source including projecting a serial spot sequence from a sequential, one-dimensional series of spots on the retina, wherein the individual spots indicate the coagulation sites; waiting for confirmation of the sequence of individual spots; after confirming, recalculating an automated sequence of steps having a further serial spot sequence and projecting them on the retina according to the first step; and subsequent repeating of the second and third steps. Also, a system for coagulating the retina, having an imaging diagnostic unit, a therapy beam for coagulating coagulation sites, a pilot beam for marking the coagulation sites by a spot sequence, a beam deflecting unit for generating the spot sequence and for positioning the therapy beam, an electronic control unit for controlling the above devices, a software interface, and an interactive interface.

An attachment for a contact lens that comprises a first part provided to be held in position against an eye and a second part connected to the first part. The second part is for fixing the attachment to a contact lens. The first part corresponds to a distal side of a contact lens and forms at least one of a sterile or a disinfected bearing surface for the eye. The second part is configured to connect the attachment to the contact lens and to bring the first part to rest against a distal side of the contact lens.

A device for examining the eye fundus and photoreceptors includes an illumination beam path having optical beam forming and/or guiding components, at least one illumination unit for providing a continuous illumination and a flash illumination, and an observation and imaging beam path having optical beam forming and/or guiding components and a device for varying the magnification, including a beam splitter for splitting the observation and imaging beam path. A rotatable diffraction grating is disposed in a plane in the observation and imaging beam path that is conjugate to the object plane and the movement of the grating is synchronized with the illumination unit that serves as the flash illumination so that an image recording sensor records a rapid sequence of images of the eye fundus at different positions of the grating and said sequence is forwarded to an existing evaluation unit.
