The fiber slit illuminator is indicated for use as an alternative illumination system to the surgical microscope in ophthalmic microsurgery for procedures on the anterior and posterior segments of the eye. The fiber slit illuminator is not equipped with a light source, but uses the light transferred from the microscope by a light guide.

Device Description

The VISULUX is intended to be used together with a microscope to perform ophthalmic observations. The device is primarily used by surgical ophthalmologists. As the device has no own light source the microscope must provide an additional separate light source or at least a separate S-light guide to be connected to the VISULUX. The light is brought by a light guide in the device and is channeled through an optical system to leave the device as a bright, sharp slit. The operator can adjust the beam with a slideable aperture to have different widths.
