  • Patent number: 8801634
    Abstract: For use with a surgical tool for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis, a system and method is disclosed for determining a position on the sclera for locating the scleral pocket. The system and method determines an optimum location for the scleral pocket. The system and method determines a location on the sclera that represents the intersection of the lens equatorial plane with the external surface of the sclera. The front of the scleral pocket is placed at a location that is four hundred fifty microns posterior to the intersection of the lens equatorial plane with the external surface of the sclera.

  • Patent number: 8623037
    Abstract: A system and method is disclosed for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The system and method comprises a surgical tool comprising a surgical blade for making incisions in the sclera of an eye. When a surgeon places the surgical blade on the sclera of the eye a pressure sensor in the surgical tool determines whether there is sufficient pressure between the surgical tool and the sclera of the eye for the surgical tool to operate properly. The surgeon activates the surgical tool to cause the surgical blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the surgical blade is rotated back out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.

  • Patent number: 8500767
    Abstract: A surgical blade is disclosed for use with a surgical tool for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The surgical blade comprises a rotatable support arm capable of being rotated by the surgical tool and a detachable curved cutting blade for making incisions in the sclera of an eye. The surgical tool causes the curved cutting blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the curved cutting blade is detached from the rotatable support arm. The curved cutting blade is then removed from the incision by pulling the curved cutting blade forward out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.

  • Patent number: 5993500
    Abstract: Volatile organic components are controlled in electronic component assembly processes to prevent deposits on finished circuit boards and the like. The method of controlling the components in a machine having a plurality of enclosed heating zones followed by at least one cooling zone containing gas, and a conveyor for passing circuit boards therethrough on a conveyor path, comprises the steps of removing a portion of gas from at least one of the heating zones, cooling and filtering the portion of gas remote from the heating zones and the cooling zone to condense at least some of the volatile components in the portion of gas, and returning the cooled and filtered portion of gas to at least one other zone of the heating zones and the cooling zone.
