  • Patent number: 8771261
    Abstract: A system and method of treating target tissue that includes generating a treatment beam of light using a light source, directing the treatment beam onto target tissue using an optical element, generating an image of the target tissue from light emanating from the target tissue using a plurality of optical elements, and translating the light source, the optical element and/or the plurality of optical elements relative to the target tissue (using a translation device) to simultaneously move the treatment beam along the target tissue and the field of view of the target tissue as defined by the plurality of optical elements. Control electronics control the translation device to cause the treatment beam to move along the target tissue in a predetermined pattern.

  • Patent number: 8734433
    Abstract: A system and method for treating ophthalmic target tissue, including a light source for generating a beam of light, a beam delivery system that includes a scanner for generating patterns, and a controller for controlling the light source and delivery system to create a dosimetry pattern of the light beam on the ophthalmic target tissue. One or more dosage parameters of the light beam vary within the dosimetry pattern, to create varying exposures on the target tissue. A visualization device observes lesions formed on the ophthalmic target tissue by the dosimetry pattern. The controller selects dosage parameters for the treatment beam based upon the lesions resulting from the dosimetry pattern, either automatically or in response to user input, so that a desired clinical effect is achieved by selecting the character of the lesions as determined by the dosimetry pattern lesions.

  • Publication number: 20140142558
    Abstract: A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

  • Publication number: 20140090342
    Abstract: A filter including a filter housing with a horizontal partition wall dividing the filter housing into a dean-gas chamber and a dust chamber. The filter has an inlet part in open communication with the dust chamber. The inlet part is configured for supplying a dust-containing flow of gas to the dust chamber. The gas flow is conveyed through the filter elements and upwards into the dean-gas chamber where the filtered gas is discharged through a dean-gas outlet. In the filter housing, a cylindrical inner portion is arranged that encircles the filter elements. A round-going inlet part is opposed to the cylindrical inner part. The round-going inlet part has a larger diameter than at least a portion of the filter housing that adjoins the inlet part. Gas flow is divided into an upwardly and downwardly oriented gas flow controlled by arrangement of the cylindrical inner part.

  • Publication number: 20080049188
    Abstract: An apparatus and method for treating and/or diagnosing a patient's eye. A light source produces fixation light and procedure light. A scanning device deflects the fixation light to produce a fixation pattern of the fixation light on the eye, and deflects the procedure light to produce a procedure pattern of the procedure light on the eye. A controller controls the scanning device such that the fixation and procedure patterns move relative to each other, and/or the fixation pattern dynamically changes.

  • Publication number: 20070265602
    Abstract: A system and method for treating target tissue including a light source for generating a beam of light, a plurality of optical fibers, a deflection device configured to selectively deflect the light beam into the input ends of the optical fibers, one optical fiber input end at a time, and a probe having a tip with the output ends of the optical fibers and configured for insertion into target tissue. The probe tip is configured to sequentially project spaced apart spots of the light beam from the output ends as the deflection device deflects the light beam into the optical fibers. One or more moving or static deflecting optics at the probe tip can be used to statically or dynamically deflect the beam exiting the optical fibers.
