Patent ID: 7288106

Claim:
A system for illuminating a target area of an eye treated with a photosensitizer, the system comprising: a contact portion configured to interface with the eye to provide an optical path between the eye and the system; a plurality of light emitters configured to emit light having an emissions spectrum with at least an activation wavelength of the photosensitizer; a selective reflector configured to reflect at least a majority of light having the activation wavelength of the photosensitizer and to pass at least some light having wavelengths other than the activation wavelength, the selective reflector positioned to receive emitter light and to direct a portion of the emitter light reflected from the selective reflector toward the contact portion, the selective reflector positioned to receive and pass a portion of light reflected from the eye and passed by the contact portion; and a visualization portion positioned to receive and pass that portion of light reflected from the eye and passed by the selective reflector, wherein each of the light emitters has a light source and includes a lens having a focal length and being spaced from the light source of the light emitter by substantially the focal length of the lens.
