Abstract
A compact UV light delivery device comprises a UV LED, integrated into the compact UV light delivery device, to generate a UV beam; a homogenizing beam coupler, to receive the UV beam from the UV LED, and to homogenize the UV beam such that a measure of non-uniformity of the output homogenized beam is smaller than the measure of non-uniformity of the received UV beam; an illumination optics, to receive the homogenized beam and to forward it as an illumination beam; a spatial light modulator, to modulate the illumination beam into a modulated beam according to a procedure profile; a projection optics, to receive and to project the modulated beam as a projection beam through its objective into an eye of a patient; and a binocular-free imaging system, to image the eye of the patient via the same objective, and to present the image on a user interface.
