An ophthalmological device for cutting into a nucleus of a cataract comprises a phaco tip including a body having at a distal end thereof a solid blade with a face edge adapted to be placed in contact with the nucleus. There is no aspiration port in this face edge. An aspiration port in the body is displaced rearward from the face edge by a distance which is greater than the length of the blade. A sleeve fits over the body and has a forward section that terminates in an opening in advance of the aspiration port. The device is used alternately with a standard phaco tip to remove cataracts. A surgical instrument comprises a handpiece including phaco tip having a face edge having aspiration port therein that is adapted to be placed in communication with a source of aspiration. A control unit regulates the application of aspiration to the aspiration port, enabling aspiration at the aspiration port to be discontinued on command.

The horizontal base of an L-shaped blade is inserted within an existing incision performed as part of a traditional radial keratotomy procedure to permit an intrastromal cut to be made to urge corneal collapse and provide myopia correction without incurring glare and central vision distortion for the patient. The base of the blade extends approximately 1 mm to a very sharp vertical edge from the vertical arm attached to a blade holder to permit up to an equivalent length intrastromal cut until the end of the arm reaches the end of the preexisting incision through Bowman's membrane and the epithelium. The height of the base and length of the cutting edge is approximately 450 microns to prevent cutting or perforation of either of Bowman's or Descemet's membranes.
