Patent number: 9233021Abstract: In various embodiments, a phacoemulsification cutting tip with a straight shaft and an angled portion off of the straight shaft may include a hook on the angled portion to move an axis of rotation of the cutting tip closer to alignment with an extended centerline of the shaft. The cutting tip may be configured to torsionally rotate back and forth on an axis perpendicular to a centerline of the shaft (e.g., rotation around a y-axis). In some embodiments, lateral vibrations (e.g., side to side along an x-axis or z-axis perpendicular to the y-axis) that result from torsional rotation around the y-axis in a cutting tip without the hook may be reduced through use of the hook to balance the otherwise eccentrically weighted hook.Type: GrantFiled: October 24, 2013Date of Patent: January 12, 2016Assignee: Alcon Research, Ltd.Inventors: Alexander N.

Patent number: 8937769Abstract: A system comprises first and second beamsplitter modules aligned along an alignment line. In certain embodiments, each beamsplitter module can split a beam traveling along a first optical path into a first split beam and a second split beam within a spectral range. Each beamsplitter module can transmit the first split beam along the first optical path and direct the second split beam along a second optical path substantially orthogonal to the first optical path and to the alignment line. In certain embodiments, each beamsplitter module can receive a first beam traveling along a first optical path and a second beam traveling along a second optical path that is substantially orthogonal to the first optical path and to the alignment line. Each beamsplitter module can combine the second beam with the first beam to yield a combined beam and transmit the combined beam along the first optical path.Type: GrantFiled: June 7, 2012Date of Patent: January 20, 2015Assignee: Alcon Research, Ltd.Inventors: Alexander N.

Patent number: 8662670Abstract: An ophthalmic illuminator includes a one or more light combining stages arranged in series to augment a white light source with various color spectral bands. A first stage combines white light from a white light source with colored light from a first color source. Each subsequent stage in the series adds its own respective colored light. The color sources may be selectively turned on/off or driven with variable amounts of power. In this fashion, a combined light is produced by the final stage that represents a desired chromaticity and brightness as desired for a particular ophthalmic therapeutic procedure.Type: GrantFiled: March 31, 2011Date of Patent: March 4, 2014Assignee: Alcon Research, Ltd.Inventors: Michael Papac, Ronald T.
