Patent number: 10022270Abstract: Methods and systems for performing laser-assisted surgery on an eye form a layer of bubbles in the Berger's space of the eye to increase separation between the posterior portion of the lens capsule of the eye and the anterior hyaloid surface of the eye. A laser is used to form the layer of bubbles in the Berger's space. The increased separation between the posterior portion of the lens capsule and the anterior hyaloid surface can be used to facilitate subsequent incision of the posterior portion of the lens capsule with decreased risk of compromising the anterior hyaloid surface. For example, the layer of bubbles can be formed prior to performing a capsulotomy on the posterior portion of the lens capsule.Type: GrantFiled: February 26, 2014Date of Patent: July 17, 2018Assignee: OPTIMEDICA CORPORATIONInventors: Georg Schuele, Julian Stevens, Dan E. Andersen

Publication number: 20170266042Abstract: System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.Type: ApplicationFiled: June 1, 2017Publication date: September 21, 2017Inventors: DANIEL V. PALANKER, MARK S. BLUMENKRANZ, DAVID H. MORDAUNT, DAN E. ANDERSEN

Publication number: 20160074216Abstract: 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.Type: ApplicationFiled: November 24, 2015Publication date: March 17, 2016Applicant: Topcon Medical Laser Systems, Inc.Inventors: Daniel V.
