    摘要: A method for ocular surgery requires use of a delivery system for generating and guiding a surgical laser beam to a focal point in a treatment area of an eye. Additionally, a contact device is employed for using the eye to establish a reference datum. Further, an optical detector is coupled to the beam path of the surgical laser to create a sequence of cross-sectional images. Each image visualizes both the reference datum and the focal point. Operationally, a computer then uses these images to position and move the focal point in the treatment area relative to the reference datum for surgery.

    摘要: A system and method are provided for simulating a Laser Induced Optical Breakdown (LIOB) protocol to establish a surgical LIOB treatment for a patient. In the system, a library of finite element models characterizing various visual defects in corneas are programmed into a computer. Further, a library of nomograms indicating specific LIOB protocols for correcting respective visual defects are programmed into the computer. As a result, a model and a corresponding nomogram may be selected in view of a patient's diagnostic information. Further, the selected model may be individualized with the diagnostic information to more precisely characterize the patient's visual defects. Thereafter, the computer simulates the indicated LIOB protocol on the individualized model in order to achieve a desired corneal configuration. When the desired corneal configuration is achieved, the final treatment plan may be determined.

    摘要: A system and method for performing laser induced optical breakdown (LIOB) in corneal tissue of an eye requires calculating a pattern of focal spots. LIOB is then induced at a first focal spot, and is continued at a plurality of interim focal spots within a time period τ. Each focal spot has a diameter “d1” and generates a temporal cavitation bubble of diameter “d2”. It then collapses within time “τ” to a substantially stationary diameter “d3”, with (d1≦d3≦d2). Importantly, each focal spot is located more than “d2” from every other interim focal spot within the time period of “τ”. At the time “τ”, a second focal spot in the pattern can be generated at a distance “d3” from the first focal spot. This process is then continued with another plurality of interim focal spots being generated within another time period “τ”.

    摘要: The present disclosure relates to an eye treatment system for performing laser surgery on an eye which includes a laser optical system. The laser optical system includes a scanning system for scanning a focus of a laser beam of the laser light within a cornea of the eye in three dimensions. The laser optical system further includes a focusing optical system. The scanning system is in the beam path of the laser beam between the laser source and the focusing optical system. The eye treatment system further includes a contact element which is in the beam path of the laser beam between the focusing optical system and the eye. The contact element has a contact surface for contacting a cornea of the eye. At least a portion of the contact surface has a shape, which is convex toward the cornea.

    摘要: A system and method are provided for removing a natural lens and inserting an Intraocular Lens (IOL) into the lens capsule of an eye. Specifically, this is accomplished by inserting the IOL through an opening on the posterior capsule that is created using a focused laser beam. The system includes a laser unit, a detector for creating images of the interior of the eye, and a computer that controls the cooperative functions of the detector and the laser unit. Based on images of the posterior capsule provided by the detector, the computer is used to control movements of the focal point through tissue of the posterior capsule to perform Laser Induced Optical Breakdown (LIOB) on posterior capsule tissue. The result is a laser capsulotomy that creates an opening through the posterior capsule allowing the natural lens to be removed and the IOL to be implanted.

    摘要: In accordance with the present invention, a system and method are provided for controlling postoperative shrinkage of the capsular bag, after the lens has been removed from the capsular bag. The purpose is to establish a proper optical alignment for a prosthetic Intraocular Lens (IOL). Included in the system are a laser unit for generating a laser beam, a detector for creating an image of the prosthetic IOL in the capsular bag, and a computer for evaluating the image to determine an alignment difference between the IOL axis and a defined axis of the eye. The computer is also used for guiding the laser beam to alter selected tissue in the eye, to thereby influence postoperative shrinkage of the capsular bag and minimize any potential alignment difference between the IOL axis and the defined axis of the eye during capsular bag shrinkage.

    摘要: The invention relates to an apparatus and a method for determining the applicability of a treatment pattern for manipulation of a cornea of an eye using a laser. The concept of the present invention is based on the determination of an actual volumetric profile based on a set of input data and a theoretical volumetric profile which is created independently based on only the basic optical parameters. On the basis of a comparison of the determined volumetric profiles it is determined whether the actual volumetric profile is within predetermined tolerances.

    摘要: A method and system for customizing a flap created from a transparent material compensates for aberrations, particularly higher order aberrations, which are pre-existing or otherwise induced during creation of the flap. Before flap creation, the distorted wavefront of the transparent material is determined and the topology of the transparent material is defined in order to predict contributions likely to be encountered or induced by the stress distribution during creation of the flap. In view of the topology of the transparent material, a prototypic dissection path based on the distorted wavefront is refined to establish a refined dissection path. As a result, the flap is created along the refined dissection path to correct and minimize or eliminate the formation of higher order aberrations.
