An adjustable ophthalmic surgery chandelier illuminator has a glass optic fiber with a conical exterior surface at its distal end that disburses illumination in the interior of the eye. The glass fiber is contained in a retractable needle that has a long, sharp beveled surface that facilitates insertion of the needle and the optic fiber into the eye, and then is retracted relative to the fiber distal end to adjust the field of illumination inside the eye.
