Abstract
Abstract A laser probe including a handpiece and a rigid cannula fixed to the handpiece to prevent relative translational movement-therebetween. An optical fiber for delivering laser energy is supported for translational movement relative to the handpiece. A slidable button is fixed to the optical fiber via a rigid sleeve such that the button and optical fiber move together in the same direction during operation. The fiber may be selectively positioned relative to the button to cause the button to act as a visual indicator of the direction in which the fiber will extend from the cannula. The button may be specially configured with an enlarged head portion to enhance grippability and smooth operation of the button.
