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： A device and method are provided for grafting a donor component onto a recipient member. In the method, a void in the recipient member is defined by a boundary with predetermined dimensions. Similarly, the donor component is specified as having a boundary with predetermined dimensions that are substantially compatible with the void. Thereafter, suture paths are created in the donor component and the recipient member. When the donor component has been positioned in the void of the recipient member, the suture paths are aligned. Then, a suture is passed through the suture path and across the respective boundaries to secure the donor component to the recipient member.

摘要： A method for photodisrupting a preselected subsurface volume of corneal tissue to alter a cornea's refractive properties is disclosed. Specifically, at least one stromal volume having a substantially conical shaped surface is photodisrupted. For this purpose, a laser device having a laser source, laser scanner and one or more optical elements is typically used. In one embodiment, a plurality of stromal volumes, with each stromal volume having a substantially conical shaped surface, is sequentially photodisrupted to form a contiguous stromal cavity. In a particular implementation, each conical shaped surface defines a cone axis that is aligned to be co-linear with a reference axis that passes through the anterior surface of the eye and may be aligned orthogonally to the anterior surface of the eye.

摘要： A system for producing polychromatic light having selectively shaped wavefronts includes a source for generating light beams of at least two wavelengths (λ1, λ2). The beams are made up of a plurality of contiguous sub-beams that establish λ1 and λ2 wavefronts. From the source, the light is directed toward an optical phase shifting device which can include one or more arrays, with each array having a plurality of elements. Functionally, within a particular array, each element is independently adjustable to selectively alter the optical pathlength of a corresponding sub-beam. For light having two wavelengths (λ1, λ2), a first array configuration is used to reshape the λ1 wavelength light and a second array configuration is used to reshape the λ2 wavelength light. After wavefront reshaping, the λ1 and λ2 wavelength light is directed onto a common beam path where it can be viewed, imaged or further processed.

摘要： A system for performing a corneal transplantation includes a laser source for generating a laser beam and a chair for positioning a patient relative to the laser source. A stabilizing element, engageable with the laser source, is fixated on the anterior surface of the patient's cornea to hold the cornea in alignment with the laser source. The laser source is then used to remove diseased tissue from the cornea of the patient, thereby creating a corneal cavity of known dimensions. In a subsequent step, a donor graft that was previously photoaltered to have substantially the same dimensions as the corneal cavity, is transplanted into the corneal cavity.

摘要： A method and device for photoablation is disclosed wherein photoablation occurs along the interface between a material having a lower energy ablation threshold and a material having a higher energy ablation threshold. The method and device utilize a laser beam having a beam energy density which is less than the higher energy ablation threshold and greater than or equal to the lower energy ablation threshold. By directing such a laser beam to the interface, the material having the lower energy threshold is photoablated while the material having the higher energy threshold is largely unaffected.

摘要： A device for establishing a desired alignment between a patient's eye and a laser system to facilitate an engagement therebetween includes a light source to illuminate the eye. A moveable platform is provided to move the patient relative to the laser system. To establish alignment between the eye and the laser system, a reference marker is based on the laser system. An image of the marker, along with reflections from the illuminated eye, is then transmitted to the system controller. There, the image and reflections are processed to determine a measured alignment that is then compared to the desired alignment. An error signal that is indicative of an alignment difference is then generated and used to incrementally move the platform, or the patient, in an appropriate direction.

摘要： A system and method for dissecting a transparent material utilizes pre-dissection diagnostic information about the transparent material. Specifically, in the system and method, a prototypic dissection path is planned to achieve a desired result. Then, the topology of the transparent material is defined and analyzed to calculate a predicted result of a dissection along the prototypic dissection path. After comparing the desired result and the predicted result, a refined dissection path is established in which any difference between the predicted result of a dissection along the refined dissection path and the desired result is minimized. As a result, dissection of the transparent material along the refined dissection path achieves the desired result.
