20110264081 | OPHTHALMOLOGICAL LASER SYSTEM AND OPERATING METHOD - A polarization beam splitter selectively decouples detection light onto a detector such that it has a polarization direction that differs from the emitted illumination light. This enables the detection of the light scattered back in the eye lens at a high level of accuracy, since stray light from reflections at optical components of the light path is suppressed. In the generating of photo disruptions or other incisions, the ray exposure of the retina may be reduced in that the incisions being furthest away from the laser are induced first such that laminar gas inclusions with an existence duration time of at least 5 seconds result. In this manner the laser radiation propagated in the direction of the retina in further incisions are scattered and partially reflected such that the influence impinging upon the retina is reduced. | 10-27-2011 |
20120016352 | OPHTHALMOLOGIC LASER SYSTEM - An ophthalmological laser system for photodisruptive irradiation of ocular tissue, including a crystalline lens or a cornea. The system includes an ultra-short pulse laser, the radiation of which is focusable as illumination light via an illumination beam path including a scanner unit and focusing optics. A control unit is programmed to execute determining irradiation control data for photodisruptions at irradiation points in an interior of the ocular tissue distributed three-dimensionally and non-equidistantly to create at least one predetermined target incision. The laser system then irradiates the ocular tissue according to the determined irradiation control data. | 01-19-2012 |
20120310337 | METHOD AND ARRANGEMENT FOR SELECTING AN IOL AND/OR THE SURGICAL PARAMETERS WITHIN THE FRAMEWORK OF THE IOL IMPLANTATION ON THE EYE - Selection of an appropriate intraocular lens (IOL) and/or the applicable surgical parameters for optimizing the results of refractive procedures on the eye. Features of the IOL are crucial for the selection and/or adjustment of the optimal IOL, but so is the IOL selection method (and parameters) from a surgical perspective. For the method, corresponding output parameters are determined from predetermined, estimated, or measured input parameters and/or their mean values, wherein at least two input parameters are varied with one another and which have at least one input parameter as a distribution function. The resulting function is optimized by means of corresponding target values and the determined distribution function of one or more output parameters is used as a decision aid. The present solution is used for selecting an appropriate IOL and/or the applicable surgical parameters and is applicable in the field of eye surgery for implanting IOLs. | 12-06-2012 |
