Apparatus and method for the removal of lens tissue includes a first handpiece having a laser emitting probe sized for insertion into a lens capsule and radiating a lens therein. A brake pedal engages a sensor that encodes the pedal position as an electronic signal. The resulting components exhibit superior thermal performance and enhanced resistance to ion erosion and pitting. % of the total of the thermoplastic resin, the colloidal inorganic substance and the thermoplastic resin fine particles. A heating element is formed within the sidewall of the heat shield. The properties of the document are then mapped to those tables in the database which include a property group that has been determined to apply to the document.
