Abstract
A laser surgical device for removal of intraocular tissue including a handpiece and a tip. The handpiece has a sleeve that creates a passage way for irrigation fluid. An optic fiber or similar light conveying means is contained within the handpiece. A passageway for aspiration is included in the handpiece and continues into the tip. The tip is configured with a photon trap that captures stray laser light and prevents it from continuing into the eye.
