Patent number: 9107731Abstract: A method for performing a corneal ablation procedure on an eye of a patient including determining a refractive correction for the eye and determining a first parameter corresponding to the refractive correction or a condition of the patient. An ablation profile is selected that includes a refractive correction component and a pre-compensating component that is selected based on the first parameter. The ablation profile is configured to promote a controlled induction of a higher order aberration, where the pre-compensating component limits the induction of the higher order aberration to be within a predefined range. The cornea is ablated using the selected ablation profile.Type: GrantFiled: September 6, 2011Date of Patent: August 18, 2015Assignee: CARL ZEISS MEDITEC AGInventors: Dan Z.

Patent number: 9107612Abstract: A wavefront sensor is integrated with a surgical microscope for allowing a doctor to make repeated wavefront measurements of a patient's eye while the patient remains on an operating table in the surgical position. The device includes a wavefront sensor optically aligned with a surgical microscope such that their fields of view at least partially overlap. The inclusion of lightweight, compact diffractive optical components in the wavefront sensor allows the integrated device to be supported on a balancing mechanism above a patient's head during a surgical procedure. As a result, the need to reposition the device and/or the patient between measuring optical properties of the eye and performing surgical procedures on the eye is eliminated. Many surgical procedures may be improved or enhanced using the integrated device, including but not limited to cataract surgery, Conductive Keratoplasty, Lasik surgery, and corneal corrective surgery.Type: GrantFiled: March 12, 2013Date of Patent: August 18, 2015Assignee: WaveTec Vision Systems, Inc.Inventors: Anthony Y.

Patent number: 9034024Abstract: A minimally invasive method for treating varices in especially sensitive areas, including pelvic varices in females, varicoceles, and also oesophageal varices is presented. The method comprises the steps of making a micro incision into the blood vessels of a patient, endoscopically inserting a catheter device into the blood vessel of a patient and advancing the distal end of the catheter to reach the varix or varices. For treatment of male varicocele, insertion is preferably made directly at the testicle. Alternatively, insertion can be made in the femoral vein and advanced using a catheter. Preferably, x-ray, angiography, or other imaging techniques are used to visualize and position the catheter.
