Patent number: 10716706Abstract: A system and method are provided for fragmenting a crystalline lens, to facilitate its removal from the lens bag during an ophthalmic laser surgery. First, a predetermined pattern is used to make Laser Induced Optical Breakdown (LIOB) cuts that section the lens into asymmetrical, operational segments. At least one operational segment is then selected and softened with a plurality of compact LIOB cuts. Once softened, the selected segment is aspirated. The remaining operational segments are then subsequently removed. During a procedure, an imaging unit can monitor movements of the lens bag to ensure proper placement of the LIOB cuts on the lens.Type: GrantFiled: March 30, 2012Date of Patent: July 21, 2020Assignees: BAUSCH & LOMB INCORPORATED, TECHNOLAS PERFECT VISION GMBHInventors: Frieder Loesel, Jochen Kandulla, Friedrich Moritz, Gwillem Mosedale, Holger Schlueter, Roland Toennies, Gerhard Youssefi, David Haydn Mordaunt

Publication number: 20140276670Abstract: A system and method are provided for establishing precise locations for a focal point of a laser beam within a predetermined scanning range during ophthalmic laser surgery. An important aspect of the present invention is the use of a tolerance for deviation of the laser beam's focal point from the laser beam path. The purpose of the tolerance is to ensure that the surgical procedure is effective and that collateral damage to non-targeted tissue does not occur. The present invention accounts for deviations caused by various factors during a procedure. A computer is provided to ensure that the cumulative effect of all deviations maintains the focal point within the tolerance.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: Technolas Perfect Vision GmbHInventors: Holger Schlueter, Roland Toennies, Gwillem Mosedale

Patent number: 8556885Abstract: A system and method are provided in which an iris or eye image is taken during a refractive diagnostic analysis. The image is employed for aligning data from the analysis with data from other refractive analysis instruments, as well as aligning a refractive surgical tool, such as a laser, with the eye for treatment. Further, the stored iris image is compared with the patient's iris before treatment, verifying that the correct eye is to be treated with a developed treatment pattern. A variety of refractive instruments can be used, such as corneal topography systems and wavefront aberration systems.Type: GrantFiled: November 9, 2006Date of Patent: October 15, 2013Assignee: Bausch & Lomb IncorporatedInventors: Kristian Hohla, Thomas Neuhann, Gerhard Youssefi, Roland Toennies

Publication number: 20130053837Abstract: A system and method are provided for docking a patient interface device to the eye of a patient using suction. The patient interface device is formed by the structural cooperation of a base member and an attachment member, both of which have an open distal end. A contact lens is formed onto the open distal end of the base member, and a continuous abutment is formed onto the open distal end of the attachment member. When the interface device is placed onto the eye of a patient, only the continuous abutment contacts the sclera of the patient. An air pocket is formed between the contact lens and the continuous abutment. The air pocket is in fluid communication with a vacuum channel. A vacuum pump is then employed to suction the air from the air pocket and draw the surface of the eye into contact with the contact lens.Type: ApplicationFiled: August 31, 2011Publication date: February 28, 2013Inventors: Jochen Kandulla, Roland Toennies, Markus Hailmann, Michael Tewes

Publication number: 20120303007Abstract: A system and method are provided for using multiple detectors to create a frame of reference for performing ophthalmic laser surgery. Anatomical detectors generate data sets and a computer program receives these data sets to create the frame of reference. The frame of reference is then used with a selected procedure for conducting ophthalmic laser surgery. An additional detector can measure refractive data of the eye for use as a data set that will refine the frame of reference.Type: ApplicationFiled: May 27, 2011Publication date: November 29, 2012Inventors: Frieder Loesel, Roland Toennies

Patent number: 8303578Abstract: The invention relates to a system and a method for the treatment of a patient's eye. The system comprises a laser apparatus, a scanning apparatus and an eye tracking apparatus for determining the actual position of the patient's eye and for generating alignment data of the patient's eye relative to a reference position of the patient's eye to the laser, said eye tracking apparatus being provided with a desired treatment shot file. Said scanning apparatus is connected via a first bidirectional bus to the eye tracking apparatus, said laser apparatus is connected via a second bidirectional bus to the eye tracking apparatus. The eye tracking apparatus adjusts the position data for each shot based on said alignment data of the patient's eye and provides aiming control signals representative of the target position data to the scanning apparatus for said shot via said first bidirectional bus.Type: GrantFiled: September 27, 2006Date of Patent: November 6, 2012Assignee: Technolas Perfect Vision GmbHInventors: Stefan Lang, Roland Toennies

Publication number: 20080186480Abstract: The present invention is based on the concept to detect the noise which is generated when a laser pulse of the excimer laser hits on a reference material. In particular where the laser pulse of an excimer laser hits on a reference material the radiation ablates a corresponding volume of the reference material by photodecomposition. The ablated volume of material which is proportional to the pulse energy applied to the reference material can be determined based on measuring the acoustic shock wave resulting from the ablation. The reference material is preferably a plate made of a material erodable by an excimer laser, more preferably a plate made of plastics and most preferably PMMA.Type: ApplicationFiled: September 27, 2006Publication date: August 7, 2008Inventors: Stefan Lang, Roland Toennies

Patent number: 7022117Abstract: An aperture card is provided for insertion into a laser refractive ablation system for use in laser ablating the cornea. The aperture card is designed for single surgical use for surgical precautionary considerations and to achieve the highest quality ablations, in addition to reproducibility. The aperture card is loaded into the laser refractive ablation system in a path between the laser system and the eye. The aperture card is precisely located by positioning means and ablative lasing action is inhibited if the card is not positioned within tolerance. Alternatively, the laser system can determine the position of the aperture card and adjust a computed ablation profile or otherwise adjust the optical system to adapt for any misalignment of the apertures in the aperture card. The card contains a “soft spot” aperture capable of shaping a spatial intensity distribution with a unique profile.Type: GrantFiled: October 20, 2000Date of Patent: April 4, 2006Assignee: Bausch & Lomb IncorporatedInventors: Kristian Hohla, Gerhard Youssefi, Roland Toennies
