Patent number: 8414123Abstract: Proper selection and centering of an intraocular lens (IOL) is provided. An image of an eye, which may be captured during pre-operative tests and provided to a program operable to calculate the power and axis orientation of the IOL, is used to determine the location and orientation of the IOL. This produces an output or placement guide used to properly center and orient an IOL within the eye.Type: GrantFiled: August 11, 2008Date of Patent: April 9, 2013Assignee: Novartis AGInventors: Mikhail Boukhny, Steven Bott

Publication number: 20050137586Abstract: A system and method for tracking ocular changes during a surgical procedure include directing an eye-safe optical beam toward an undilated, unparalyzed eye. A reflected optical beam is detected, and measurements are performed based upon data contained in the reflected optical beam of at least one geometric parameter of the eye at a predetermined frequency, and from them is calculated a change in the at least one geometric parameter. The calculated change is used to dynamically adjust the directing of laser beam shots during the surgery.Type: ApplicationFiled: December 22, 2004Publication date: June 23, 2005Inventors: Gary Gray, John Campin, Steven Bott, David Gibbs, George Pettit

Patent number: 5871946Abstract: An assay compound or a salt thereof for assaying the activity of an enzyme inside a metabolically active whole cell is disclosed. The assay compound includes a leaving group and an indicator group. The leaving group is selected from the group comprising amino acids, peptides, saccharides, sulfates, phosphates, esters, phosphate esters, nucleotides, polynucleotides, nucleic acids, pyrimidines, purines, nucleosides, lipids and mixtures thereof. The indicator group is selected from compounds which have a first state when joined to the leaving group, and a second state when the leaving group is cleaved from the indicator group by the enzyme. Preferably, the indicator compounds are rhodamine 110, rhodol, and fluorescein and analogs of these compounds. A method of synthesizing the compound as well as methods of using these compounds to measure enzyme activity are also disclosed.Type: GrantFiled: May 18, 1995Date of Patent: February 16, 1999Assignee: Coulter CorporationInventors: Frank J.
