A system and apparatus for increasing the amplitude of accommodation and/or changing the refractive power and/or enabling the removal of the clear or cataractous lens material of a natural crystalline lens is provided. Generally, the system comprises a laser, optics for delivering the laser beam and a control system for delivering the laser beam to the lens in a particular pattern. There is further provided a range determining system for determining the shape and position of the lens with respect to the laser. There is yet further provided a method and system for delivering a laser beam in the lens of the eye in a predetermined shot pattern.

According to an aspect, there is provided a treatment device (2; 30; 60; 130) for performing light-based treatment operations on or to a subject. The treatment device (2; 30; 60; 130) comprises a light source (12) for generating light for performing the treatment operation; a dichroic filter (34; 64; 104; 134) arranged at a first angle with respect to the incident light such that the incident light is separated into a transmitted light component and a reflected light component according to a cut-off wavelength of the dichroic filter (34; 64; 104; 134), wherein the transmitted light component is transmitted through the dichroic filter (34; 64; 104; 134) and the reflected light component is reflected by the dichroic filter (34; 64; 104; 134); a light exit window (10) through which a light component is emitted from the treatment device (2; 30; 60; 130); a beam dump (44; 74; 140) configured to absorb a light component; and a heat sink (46; 76; 142) coupled to the beam dump (44; 74; 140) to dissipate heat from the beam dump (44; 74; 140). The light exit window (10) and beam dump (44; 74; 140) are arranged with respect to the dichroic filter (34; 64; 104; 134) such that one of the transmitted light component and the reflected light component is emitted from the treatment device (2; 30; 60; 130) via the light exit window (10) and the other one of the transmitted light component and reflected light component is incident on the beam dump (44; 74; 140). The dichroic filter (34; 64; 104; 134) is provided on a first surface of a solid dichroic prism (38; 68) or an internal surface in a solid dichroic cuboid.

A catheter system for treating a treatment site within or adjacent to a vessel wall includes a light source, a balloon, a light guide, and an optical analyzer assembly. The light source generates light energy. The balloon is positionable substantially adjacent to the vascular lesion. The balloon has a balloon wall that defines a balloon interior that receives a balloon fluid. The light guide receives light energy from the light source at a guide proximal end and guides the light energy toward a guide distal end and into the balloon interior. The optical analyzer assembly is configured to optically analyze light energy emitted from the guide proximal end of the light guide.
