Patent number: 10219695Abstract: A first light source producing a first light beam with a first intensity and a second light source producing a second light beam with a second intensity. A light filter device receives the first light beam and transmits a filtered portion of the first light beam. A first angling device reflects the filtered portion of the first light beam in a first angled direction and a second angling device reflects the second light beam in a second angled direction. A mirror receives and in turn reflects the filtered portion of the first light beam reflected by the first angling device and the second light beam reflected by the second angling device to form a converged light beam with a third intensity.Type: GrantFiled: August 18, 2017Date of Patent: March 5, 2019Assignee: DOHENY EYE INSTITUTEInventors: Prashant Bhadri, James Lescoulie, Sophia Fang, Matthew McCormick, Ralph Kerns, Mark Humayun, Aaron Barnes

Publication number: 20190000507Abstract: Various adjustable cannula systems are provided. The systems can include an adjustable cannula capable of expansion and/or contraction having an elongate body with a distal end and a proximal end. The adjustable cannula can be coupled to an upper housing and a lower housing such that rotation of the upper housing results in expansion or contraction of the adjustable cannula. The adjustable cannula can also have a proximal end having a lumen larger than a distal end lumen. A plurality of flanges can be formed in the elongate body by a plurality of slits that span a majority of a length of the cannula, including along or proximate to its proximal end and distal end.Type: ApplicationFiled: September 10, 2018Publication date: January 3, 2019Inventors: Ralph Kerns, Prashant Bhadri, Matthew McCormick, Anderson Gustavo Teixeira Pinto, Mark Humayun, Luis Arana

Publication number: 20140365235Abstract: A personal surgical center embodied as a general purpose computer (e.g. laptop) with wireless technology for monitoring the operation of an independent surgical center and/or handheld instruments. The computer tracks procedures in the operating room and instruments used during those procedures, and accounts for billing, supply management, and payment options. The monitoring of the instruments used during the surgery is conducted by the personal surgical center while actual control of the settings of those instruments is via the independent surgical center or via controls included in the instruments themselves. The monitored information is stored in a log file which is then transmitted to a hospital server for generating reports, inventory control, billing, and the like. Other information generated during the procedure (e.g. doctor notes) is also stored in the log file.Type: ApplicationFiled: April 11, 2014Publication date: December 11, 2014Applicant: DOHENY EYE INSTITUTEInventors: Charles DeBoer, Matthew McCormick, Ralph Kerns, Prashant Bhadri, Lawrence Chong, Mark Humayun
