Abstract

The invention relates to a device for lighting the intraocular cavity of a human or animal eye in a controlled manner, comprising a) a socket (2) with a proximal end and a distal end, b) a shaft (3) with a proximal end and a distal end, c) a probe (4) with a proximal end and a distal end, d) a light source (5) with at least one LED, and e) an energy source (6) connected to the light source (5). The distal end of the shaft can be connected to the proximal end of the socket, the proximal end of the probe can be connected to the distal end of the socket, and the light source (5) is positioned atthe distal end of the probe (4).

Description

technical field [0001] The invention relates to a device for illuminating eyes according to the preamble of claim 1 . Background technique [0002] Intraocular illuminators for illuminating the eye are known but have disadvantages. Thus, for example, US 2004 / 0004846 A1 discloses a device comprising an LED as a light source in a housing which feeds light into an optical fiber which then illuminates the eye. A disadvantage of such an arrangement is that such an arrangement only transmits light from the light source to the location to be illuminated very inefficiently, so that only about 1% of the original light output reaches the intended location. [0003] Even when good eye or fundus illumination is required, care must be taken not to cause phototoxic damage. Good lighting depends on color temperature, emission characteristics and how bright the emitter is in the eye. These factors create power that reaches specific areas of the fundus. Bright, high-energy light has high...
