What changed

USPTO published patent application US20260083316A1 for a white-light source designed for fiber-based intraocular illumination with controllable spectral composition. The device combines at least two light sources in blue, green, and red spectral ranges, with at least one source being a laser-activated remote phosphor (LARP) light source. The system allows individual control of light beam proportions to achieve desired white-light characteristics for surgical illumination.

This patent application does not impose compliance obligations on regulated entities. Medical device manufacturers or healthcare providers interested in intraocular illumination technology may review the published claims to assess potential patent landscape considerations or licensing needs. No regulatory action or compliance deadline is associated with this patent filing.

Abstract

A white-light source for fiber-based intraocular illumination is light of controllable, spectrally broad composition and to an intraocular illumination device with corresponding controllability. Specifically, the white-light source for fiber-based intraocular illumination with light of controllable spectral composition includes at least two light sources for the provision of light beams of different colors, preferably with components substantially in the blue, the green and the red spectral range; wherein the individual light beams are combined to form a common light beam (W); wherein the white-light source is configured for individual control of the proportions of the individual light beams in the common light beam (W); wherein at least one of the light sources is a laser-activated remote phosphor light source, LARP light source, having a phosphor as conversion element and a laser diode for exciting the conversion element by means of an excitation radiation (S) emitted by the laser diode.
