Patent number: 9101446Abstract: Systems and methods of photoaltering a region of a material using a pulsed laser beam. The method includes scanning the pulsed laser beam in a first portion of the region with a first pattern, scanning the pulsed laser beam in a second portion of the region with a second pattern, and separating a flap of the material at the region. The system includes a laser, a controller selecting at least first and second patterns, and a scanner operable in response to the controller. The first pattern has a first maximum acceleration associated with the second portion, and the second pattern has a second maximum acceleration associated with the second portion. The second maximum acceleration is less than the first maximum acceleration. The scanner scans the pulsed laser beam from the laser in the first portion with the first pattern and in the second portion with the second pattern.Type: GrantFiled: March 11, 2013Date of Patent: August 11, 2015Assignee: IntraLase Corp.Inventors: Zsolt Bor, Ruben Zadoyan, Marcel Bouvier, Guy V Holland

Patent number: 7330275Abstract: The present invention generally relates to a method and system for determining the position and alignment of a plane in relation to an intersecting axis and using that known position and alignment to allow for corrections to be made when using the plane as a reference plane. More particularly, the invention relates to a method and system for determining the angle of tilt of a planar surface in relation to a laser beam, and using the determined angle of tilt to calculate a correction factor to be applied to the laser beam. Briefly stated, the method and system ultimately calculates a correction factor, z-offset, that is applied when using the laser beam in a procedure.Type: GrantFiled: November 12, 2005Date of Patent: February 12, 2008Assignee: Intralase Corp.Inventor: Ferenc Raksi

Patent number: 7027233Abstract: A closed-loop focusing system and method positions a focusing assembly to a desired positioned. A feedback positioning device, such as a linear encoder, provides an actual or “read” value for the linear movement of the focusing assembly. The desired position is compared to the actual position of the focusing assembly. If the two values are outside of a predetermined tolerance or valid range, then an audible or visual warning will be given. When a laser source is utilized with the focusing system, laser operation will be prevented if the two values are outside of an acceptable range. However, if the difference between the desired position and the actual position are within an acceptable range, the focusing assembly is repositioned to allow real-time systematic correction of the position of the focusing assembly.Type: GrantFiled: April 20, 2004Date of Patent: April 11, 2006Assignee: Intralase Corp.Inventors: Peter Goldstein, Carlos G. Suarez, Scott A. DeLong, R. K. Webb, Tibor Juhasz

Patent number: 7018376Abstract: A method for applanating an anterior surface of a cornea and coupling the eye to a surgical laser is disclosed. A interface is provided which has a central orifice and top and bottom surfaces. A suction ring is removably coupled to the bottom surface of the interface. The interface is positioned over an operative area of an eye, such that the suction ring comes into proximate contact with the surface of the eye. A suction is applied to the suction ring to stabilize the position of the interface relative to the operative area of the eye. An applanation lens is positioned in proximate contact with the operative area of the eye. Finally, the applanation lens is coupled to the interface to stabilize the position of the lens relative to the operative area of the eye.Type: GrantFiled: June 10, 2004Date of Patent: March 28, 2006Assignee: Intralase Corp.Inventors: R.

Patent number: 6991629Abstract: A disposable lens for reconfiguring the cornea of an eye for ophthalmic laser surgery includes a lens which has a flat anterior surface that is formed opposite a contact surface. A skirt surrounds the contact surface and extends outwardly therefrom to define a chamber. The skirt is formed with a groove which creates a suction channel between the skirt and the contact surface in the chamber. In its operation, the lens is positioned over the cornea and a vacuum pump is selectively activated to create a partial vacuum in the suction channel. Due to this partial vacuum, the cornea is drawn into the chamber where it is urged against the contact surface of the lens. The result of this is that the cornea is flattened into a configuration where the introduction of spherical aberration and coma into a light beam passing into the cornea is reduced or eliminated.Type: GrantFiled: August 19, 2003Date of Patent: January 31, 2006Assignee: Intralase Corp.Inventors: Tibor Juhasz, Ronald M.

Patent number: 6863667Abstract: A disposable stabilization and applanation device for reconfiguring the cornea of an eye for ophthalmic laser surgery, includes an applanation lens that is disposed in a particular spatial position with respect to an incident laser beam. The applanation lens is inserted into the central opening of an attachment ring and applanates the eye in response to pressure from a lens cone. The attachment ring is coupled to the eye and includes a skirt which surrounds the applanation lens and extends outwardly therefrom to define a chamber. The skirt is formed with a groove which defines a suction channel between the attachment ring skirt and the corneal surface of an eye. A vacuum source is connected and fluid communication with the suction channel and is selectively activated to create a partial vacuum in the channel.Type: GrantFiled: January 29, 2001Date of Patent: March 8, 2005Assignee: IntraLase Corp.Inventors: Kyle R.

Patent number: 6693927Abstract: The invention is directed to an apparatus and method for oscillator start-up control, and more particularly to an apparatus and method for overdriving a laser to obtain mode-lock operation. The oscillator with start-up control has a lasing medium mounted on a base. A laser pumping source is mounted on the base for inducing a laser beam from the lasing medium. A mode-lock detection device is mounted about the base. An overdrive circuit is coupled with the mode-lock detection and signal processing device for determining mode-lock status of the oscillator. The overdrive circuit overdrives the pump source when the oscillator is not in mode-lock status.Type: GrantFiled: September 13, 2002Date of Patent: February 17, 2004Assignee: IntraLase Corp.Inventors: Christopher Horvath, Ruben Zadoyan

Patent number: 6676653Abstract: A device for removing gas and debris from the stroma of an eye during ophthalmic laser surgery includes a contact lens that is formed with a recessed chamber. The device also includes a suction pump that is connected in fluid communication with the recessed chamber. In operation, the stroma is stabilized in the recessed chamber of the contact lens and an opening into the stroma is created. This opening is created either by the laser beam, or by a probe that is mounted on the contact lens to penetrate the stroma while the stroma is stabilized in the recessed chamber of the contact lens. Then, simultaneously or subsequently, as a laser beam is directed through the contact lens to photodisrupt tissue in the stroma the suction pump is activated to aspirate the resultant gas and debris through the opening and out of the stroma.Type: GrantFiled: December 6, 2001Date of Patent: January 13, 2004Assignee: IntraLase Corp.Inventors: Tibor Juhasz, Ronald M.

Patent number: 6648877Abstract: A method for customizing corneal corrections includes superposing an imaginary reference field (grid) on the anterior surface of the cornea of an eye to divide the corneal surface into reference areas. Also, a diagnostically determined refractive power map for the cornea is created. An incising laser beam is then directed through an individual reference area to a focal spot. Next, movement of the focal spot along the laser beam path is selectively accomplished to photoalter a predetermined volume of stromal tissue. Subsequently, based on the refractive power map, the predetermined volume of stromal tissue that is to be photoaltered is identified for each specific reference area. Accordingly, the steps of directing the beam and moving the focal spot are then repeated using selected reference areas until the required corneal correction is achieved.Type: GrantFiled: June 30, 2000Date of Patent: November 18, 2003Assignee: Intralase Corp.Inventors: Tibor Juhasz, Ronald M.
