Ophthalmic endoilluminators with directed light

A system comprising:

• a cannula having a substantially cylindrical shape defining an interior region and an opening at a distal most end of the cannula, the cylindrical shape having a cylindrical axis;
• an intermediate material disposed within the interior region, the intermediate material defining a fixed fiber pathway having a portion that is curved with respect to the cylindrical axis, the fixed fiber pathway being wider towards the opening at the distal most end of the cannula;
• an optical fiber disposed within the fixed fiber pathway, the optical fiber having a fiber optical axis and a distal end configured to emit light with an illumination pattern having an illumination axis, at least a portion of the fiber optical axis proximate the distal end not parallel to the cylindrical axis, the illumination axis not parallel to the cylindrical axis;
• and
• an actuator disposed within the intermediate material, the actuator comprising a rod configured to move the distal end of the optical fiber from a first position within the fixed fiber pathway to a second position within the fixed fiber pathway to change an angle between the illumination axis and the cylindrical axis from a first value to a second value.
