Publication number: 20160262933Abstract: Patterned laser treatment of the retina is provided. A visible alignment pattern having at least two separated spots is projected onto the retina. By triggering a laser subsystem, doses of laser energy are automatically provided to at least two treatment locations coincident with the alignment spots. All of the doses of laser energy may be delivered in less than about 1 second, which is a typical eye fixation time. A scanner can be used to sequentially move an alignment beam from spot to spot on the retina and to move a treatment laser beam from location to location on the retina.Type: ApplicationFiled: May 9, 2016Publication date: September 15, 2016Inventors: MARK BLUMENKRANZ, DANIEL V. PALANKER, DIMITRI YELLACHICH

Publication number: 20160213243Abstract: A visual function evaluation is performed using a sequence of interactions with a mobile device. A patient user may perform a variety of visual tests using the mobile device. The mobile device transmits the test results to a remote server implementing analysis of the visual function results using network service. The network service receives the test results, processes the results, and provides the processed results to a healthcare provider. The processed results may include trends of the user's visual function test performance. The healthcare provider, such as a physician, may optimize and administer treatment based on the data. Early detection of changes in visual function can enable the healthcare provider to individualize treatment, helping to prevent vision loss while minimizing visits to the office, discomfort, and expense.Type: ApplicationFiled: April 4, 2016Publication date: July 28, 2016Inventors: Daniel PALANKER, Mark BLUMENKRANZ

Patent number: 9364317Abstract: An intraocular lens assembly for positioning in a lens capsule of a patient's eye is disclosed. The intraocular lens is placed within an enclosed incision in target tissue in the patient's eye, wherein the incision is formed by a laser system including a scanner for deflecting a light beam to form an enclosed treatment pattern including a registration feature in the target tissue, and 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.Type: GrantFiled: February 10, 2010Date of Patent: June 14, 2016Assignee: OPTIMEDICA CORPORATIONInventors: William Culbertson, Mark Blumenkranz, David Angeley, George Marcellino, Michael Wiltberger, Dan Andersen

Publication number: 20150366551Abstract: Patient-supported ophthalmic platforms for use in ophthalmic procedures are described. The platform is supported at least in part upon a patient's face where the platform is configured to cover at least one or both eyes and further includes a conformable portion which rests upon a remainder of the patient's face. The platform may also integrate rests for the hands of the surgeon and may optionally integrate an instrument rest for allowing ready access of one or more surgical instruments to the surgeon. One or more corresponding eyelid speculums may also be integrated with the surgical platform eliminating the need for a separate speculum. An irrigation fluid trough may also be integrated with the surgical platform for collecting and diverting an irrigating fluid and the platform may optionally be used in combination with an oxygen delivery mask or nasal cannula.Type: ApplicationFiled: September 2, 2015Publication date: December 24, 2015Applicant: The Board of Trustees of The Leland Stanford Junior UniversityInventors: Mark BLUMENKRANZ, Kenneth N.

Patent number: 8101169Abstract: The present invention provides a method of treating an ocular disease in a subject. In a first step, a nucleic acid is introduced into cells or a tissue. The nucleic acid is introduced by electron avalanche transfection. With this technique, a high electric field induces a vapor bubble and plasma discharge between an electrode and the surrounding medium. The formation of a vapor bubble generates mechanical stress. Plasma discharge through the ionized vapor in the bubble enables connectivity between the electrode and the surrounding medium, so that mechanical stress and electric field are applied simultaneously, which results in permeabilization of the cells or tissue. This permeabilization in turn allows the nucleic acid to enter the cell or tissue. Cells or tissue containing the nucleic acid are then transplanted into an ocular region of the subject.Type: GrantFiled: August 15, 2006Date of Patent: January 24, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Thomas W. Chalberg, Jr., Mark Blumenkranz, Daniel V. Palanker, Alexander Vankov, Philip Huie, Jr., Michael F. Marmor, Michele P. Calos
