Patent number: 8968375Abstract: A method of treating a lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern of the light beam, delivering the treatment pattern to the lens of a patient's eye to create a plurality of cuts in the lens in the form of the treatment pattern to break the lens up into a plurality of pieces, and removing the lens pieces from the patient's eye. The lens pieces can then be mechanically removed. The light beam can be used to create larger segmenting cuts into the lens, as well as smaller softening cuts that soften the lens for easier removal.Type: GrantFiled: February 8, 2010Date of Patent: March 3, 2015Assignee: Optimedica CorporationInventors: William Culbertson, Barry Seibel, Neil Friedman, Georg Schuele, Phillip Gooding

Patent number: 8950405Abstract: In accordance with certain illustrative embodiments, methods and apparatuses of treating obstructive disorders of the structure of an eye or eyelid are disclosed. The treating may involve applying heat to the structure containing the obstructive disorder to melt an obstruction in the structure and place the obstruction in a melted state. The heat may be maintained for a time period to melt the obstruction and place the obstruction in the melted state. The structure may be treated by expressing the melted obstruction from the structure. The treating may be carried out either during the time period or after the time period when heat is applied but while the obstruction is in the melted state. In certain embodiments, the method further involves subsequently treating the structure by use of a pharmacological agent. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.Type: GrantFiled: October 30, 2007Date of Patent: February 10, 2015Assignee: TearScience, Inc.Inventors: Stephen M.
