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.

System and apparatus for delivering a laser beam to the lens of an eye

A method and system are provided for sensing eye movement, such as saccadic eye movement, in a non-intrusive fashion. An optical delivery arrangement converts a laser beam pulse into a plurality of light spots. The light spots are focused such that they are incident on a corresponding plurality of positions located on a boundary whose movement is coincident with that of eye movement. The boundary can be defined by two visually adjoining surfaces having different coefficients of reflection. Energy is reflected from each of the positions located on the boundary receiving the light spots. An optical receiving arrangement detects the reflected energy from each of the positions. Changes in reflected energy at one or more of the positions is indicative of eye movement.

Eye movement sensing method and system

A biofeedback method and system provide eye position feedback to a patient. A first light source produces a ring of visible light centered about an optical axis at a perceived first position. A second light source produces a dot of visible light centered on the same optical axis as that of the ring at a perceived second position. As perceived by the eye, the ring's first position is closer to the eye than the dot's second position. The eye will further perceive the dot as being centered in the ring when the eye moves its visual axis into spatial and angular alignment with the optical axis shared by the dot and ring. An eye movement sensor detects a quantifiable amount of eye movement to generate an error signal. The error signal is supplied to the second light source to adjust the dot's appearance whenever the patient needs to realign the eye's visual axis with the optical axis of the dot and the ring. The invention may also include a third light source to produce a directing light at a visually resolvable angle from the dot in a direction that is approximately opposite to the direction of eye movement.

Patient responsive eye fixation target method and system

A weapon sight assembly comprising a combined telescope 2 and laser unit 1 through which the user can view both a target and a laser light spot generated by the laser unit 1 on a target at the same time. A rhomb assembly housing 6 to direct the laser light into the side of the telescope 2 behind the objective lens 3 of the telescope 2. The emitted laser light beam is reflected by means of the rhomb assembly 6, which combines the laser light with the optical axis 22 of the sighting telescope 2, thereby eliminating the problem of parallax between the optical axis of the telescope and the emitted laser light beam. The entire weapon sight assembly is then mounted in a ring base attached to the weapon, said ring base being fully adjustable for windage and elevation.
