摘要： Biomechanical responses of the eye are used to improve photorefractive procedures. LASIK or PRK treatments, for example, can be improved by taking pre-operative measurement and predicting the corneas's biodynamic response to the ablative treatment. Predicitve use is mad of the biodynamic response of the cornea due to laser or mechanical keratectomy, that is, creating a corneal flap characterisitc of LASIK. Comparison of pre-flap and post-flap, (pre-ablation) data of the cornea such as corneal thickness, flap thickness, corneal topography and wavefront, for example, can provide predictive information applicable to modifying an ablation alorithm before the laser is engaged, either for a current operation or the development of a model. Modeling, by finite element analysis or other mathematical techniques, can also be used to predict post-operative outcomes based on a pre-operative (no flap cut or other surgical intervention) data for the cornea that is input for an accurate eye model that, in consideration of biodynamic response via the model, provides predictive information for optimizing the sucess of the refractive surgery and ultimately patient satisfaction.

摘要： A system, and process for correcting presbyopia with the system including a tissue removal system that preferably includes a laser system (200) with means (206) for forming a predetermined presbyopia correction contour corresponding to a predetermined ablation profile through controlled ablation on an exposed corneal stroma area of the eye, such that a central zone (A) of about 1 mm to 3 mm or more preferably 1.4 mm to 1.8 mm is left intact with a main maximum presbyopia ablation zone (B) bordering the untouched or hardly touched (e.g., a radius transition edge) central zone. The annular maximum ablation zone in the stroma is defined by a smoothly curving, steep profile section which extends out from a central non-ablation zone section of the profile. Further outward from the maximum ablation zone in the stroma is an annular treatment zone that is determined by a further section of the presbyopia correcting profile generally represented by a smoothing transition section that extends into another zone which is an un-ablated zone.

摘要： A system and method for determining and monitoring a laser ablation volume of a cornea (14) is disclosed. The method includes sampling a beam of laser shots from a pulsed treatment laser (11) as a reference portion (19). A fluence distribution of the beam reference portion is measured, and a laser beam characteristic is calculated (104) from the measured fluence distribution. A system for determining and monitoring a laser ablation volume of a cornea includes a beamsplitter (16) that is positioned to split a beam of laser shots from a pulsed treatment laser into a corneal portion (18) and a reference portion (19). Devices (21) are provided for measuring a fluence distribution of the beam reference portion and for calculating an ablation volume per laser shot from the measured fluence distribution.

摘要： A system and method (100) for aligning a first and a second image of an eye includes making a determination (101) of a limbus location on a first eye image and a second eye image. The limbus location of the first and the second eye images are then aligned (102) in two dimensions. A second eye feature location is determined (103) on the first and the second eye image. One of the first and the second eye image is relatively rotated (106), and a correlation is performed (107) on the first and the second eye image at a plurality of relative rotational positions using the second eye feature location. From the correlation an optimal first and second image alignment is identified (108).

摘要： A method and system (10) for improved material processing using a laser beam (12). The method and system includes directing a laser beam (12) above, at or below the surface of the material in one or more preferred patterns and with preferred laser pulse characteristics specific to the material to reduce or mitigate the accumulation or effects of gas, debris, fluid, or other by­products of photodisruption either at the location where additional laser pulses are being placed or in other sensitive locations in the material. One embodiment of a reservoir (62) is shown formed adjacent to a pattern cut (60), the primary pattern (60) is made as a raster pattern for the horizontal resection. Other pattern may be used for the primary pattern.

摘要： Methods and devices for performing corrective eye surgery generally direct a laser beam at a target region of a patient's eye (118) with the laser beam (114) having a non-uniform energy distribution profile. As ablation rates vary locally across the beam cross-section (34), the energy distribution profile is tailored to effect a uniform ablation depth (20) with each laser pulse of an excimer laser system.

摘要： The invention relates to an adapter which is used to couple a laser processing device (1) to an object (17). Said adapter comprises a central region (22) which can be placed in the beam path of the laser processing device (1); an illuminating beam path through which the illuminating beam (25) for illuminating an object field, which can be detected by the central area (22), can be conducted; an edge area (23) which is arranged outside the central area (22) to which the adapter (12) can be secured to the object (17) and/or to the laser processing device (1). The illuminating beam path extends in the edge area (23) and coupled illuminating beams (25) are directly guided to the edge area (23) and/or via the central region (22).

摘要： The present invention provides extended depth of field to human eyes by modifying contact lenses, intraocular implants, and/or the surface of the eye itself. This may be accomplished by applying selected phase variations to these optical elements (e.g., by varying surface thickness of the cornea of the eye). The phase variations EDF-code the wavefront and cause the optical transfer function to remain essentially constant within a range of distances from the in-focus position. This provides a coded image on the retina. The human brain decodes this coded image, resulting in an in-focus image over an increased depth of field.
