Definitions
- the invention relates to a method and a device for correcting visual defects in the human eye.
- AI describes a method for improving a Shack-Hartmann sensor with which wave fronts in the field of astronomy can be measured to measure stars.
- the object of the present invention was therefore to provide a method and a device which allow a complete correction of all refractive visual defects, including the aberrations of the beam path in the defective eye.
- the object is achieved by a device for correcting visual defects in an eye, comprising a coherent light source, a beam modification device for shaping and deflecting a beam from the coherent light source, a wavefront analysis device being provided for analyzing a wavefront of the beam path in the eye.
- This device makes it possible to incorporate the data obtained from the analysis of the intraocular aberration into the correction of an existing optical system of an eye to be corrected. This makes the correction of the optical system of the eye even more precise.
- a human eye is particularly suitable as an eye, but correction of the eyes of other living beings is also conceivable.
- Visual defects are, in particular, refractive visual defects such as myopia or farsightedness, irregularities in the corneal surface or aberrations in the beam path
- a laser particularly preferably a refractive laser, particularly preferably a spot scanning excimer laser system, is preferably provided as the coherent light source.
- a spot scanner with laser light in other areas of the spectrum can also be thought of, such as a frequency-quintupled YAG laser, an IR laser at 3 ⁇ m, such as an erbium: YAG laser that emits at 2.94 ⁇ m, or a Femto second laser (FS laser).
- a spot scanner with laser light in other areas of the spectrum can also be thought of, such as a frequency-quintupled YAG laser, an IR laser at 3 ⁇ m, such as an erbium: YAG laser that emits at 2.94 ⁇ m, or a Femto second laser (FS laser).
- the beam modification device preferably consists of a device for shaping a beam and a device for deflecting and aligning the beam.
- Lens systems, diffractive structures and refractive elements are preferably used as the device for shaping the beam.
- Scanner arrangements, prisms and mirrors are preferably used as the device for deflecting and aligning the beam.
- a Shack-Hartmann sensor can preferably be used as the wavefront analysis device. This is a sensor that is based on a method to analyze wave fronts. It is used particularly in astronomy (see above). Through this wavefront analysis device, the entire one emerging from the eye Wavefront are measured and information about the visual defects including the intraocular aberration of the beam path can also be obtained in the eye.
- a device in which a topography analysis unit is additionally provided for analyzing the surface of the eye.
- This analysis provides information about the curvature and contour of the surface of the eye - in particular the comea.
- This provides the system with complete data on the refractive visual defects of the eye.
- Both the possibly non-ideal surface contour of the eye - or the comea - and the intraocular aberration can now be analyzed and are available to the system when correcting the optical system of the eye. This makes it possible to completely correct the visual defects of the eye and even achieve vision that is above that of the normal human eye. It is also possible to only partially correct aberrations and thus only to produce a comprehensive correction in combination with other visual aids. It is also preferably possible to generate aberrations in a targeted manner in order to enable visual properties which are not or only rarely created by nature. These aberrations can then be used specifically for certain skills (e.g. spatial vision, accommodation, etc.).
- a device in which a control unit for processing signals from the wavefront analysis unit and / or for processing signals from the topography analysis unit, and / or for controlling the coherent light source and / or is provided to control the beam modification device.
- the data determined by the analysis units can be evaluated by these control units. It is possible to process and evaluate the signals of the wavefront analysis unit and the signals of the topography analysis unit separately in the control unit or to process both amounts of data in one step.
- the control unit preferably consists of several individual control units.
- the parameters required for beam modification are determined from this data. These parameters can preferably be used in a further step to control the coherent light source, for example to predetermine the amplitude, pulse duration and energy of the beam. These parameters are also preferably used to control the beam modification device, in order to determine the target location and the geometry of the beam in the target via the deflection of the beam.
- the shot positions for the production of the individual elements can be calculated.
- a device in which the beam modification device is designed such that an intraocular lens and / or an eye lens and / or the comea of the eye and / or a contact lens and / or an implantable contact is formed with the beam lens (ICL) and / or an eyeglass lens can be processed.
- An element or workpiece of the lens system can now be processed by the beam, which is preferably controlled by the control unit, that the vision defect or aberration is completely corrected.
- Such an element is preferably an intraocular lens (IOL) which is prefabricated before an appropriate operation. It is particularly preferably an ICL (implantable contact lens) that is placed on the lens.
- This IOL or ICL can then be shaped on the basis of the entire information available about the visual defects, including the aberration of the eye, in such a way that it corrects all existing visual defects. It is also conceivable to carry out the correction by means of the beam on the eye lens itself, which is preferably controlled by the control device.
- the object is further achieved by a method according to the invention for correcting visual defects in an eye, the beam path of the eye being determined by means of a wavefront analysis and an ideal lens system being calculated which would lead to a correction of the visual defects in the eye.
- This method is particularly preferably used using a device according to the invention. With this method, the intraocular aberration of the beam path is available for the calculation of the correction of the optical system for conversion into an ideal optical system.
- the topography of the eye is particularly preferably additionally analyzed.
- This method provides additional information on the ametropia of the eye, in particular about aberrations, asymmetrical cylinders and corneal irregularities.
- the ideal optical system is provided on the basis of the data determined from the wavefront analysis and / or from the topography analysis. Only one element from this optical system is particularly preferably provided for this.
- the correcting element or elements are produced in this way on the basis of the complete data of the ametropia. This procedure leads to the complete correction of the ametropia.
- shot positions for producing the ideal optical system are obtained from the wavefront analysis and / or from the Topography analysis calculated data calculated.
- the laser spot excimer method can advantageously be used to produce the individual elements of the optical system.
- the shot positions are optimized depending on the materials to be used and taking the production time into account.
- the old optical system of the eye is transformed into the calculated ideal optical system.
- elements of the old optical system are either processed directly, correspondingly corrected elements are produced and used, or old elements are replaced by new elements.
- This process enables the old (defective) optical system of the eye to be converted into a (new) ideal optical system.
- a new lens or an ICL according to the spot scanning principle is particularly preferably produced with an excimer laser.
- the optical system preferably comprises as elements the eye lens and / or an intraocular lens and / or the comea of the eye and / or a contact lens and / or an ICL and / or at least one spectacle lens.
- the cornea of the eye can be reshaped in order to correct the existing ametropia (e.g. the surface of the comea via photorefractive keratectomy, PRK, or by ablation of the inner tissue layers of the comea by laser assisted in situ keratomileusis, LASIK ).
- These elements not only have rotational geometry corrections, but individual structures to correct the patient's ametropia.
- intraocular lenses or contact lenses which - once inserted into the lens system - not only As before, roughly correct the ametropia of the eye, but also correct all irregularities, asymmetries and beam distortions. So that a visual acuity that is above that of the normal human eye can hardly be achieved. With this method it is also possible to manufacture spectacle lenses that also correct all irregularities, asymmetries and beam distortions of the defective eye or the old optical system.
- individual optical elements, in particular lenses, of the ideal optical system are produced in a first step for checking the ideal optical system, and in a second step these individual elements are removed and other elements, in particular the comea, are correspondingly removed reshaped.
- this lens can then be removed from the ideal optical system and the cornea can then be ideally shaped in order to provide the corresponding corrected visual acuity.
- the provisional optical element is preferably a lens which the viewer can then insert into the optical system on a provisional spectacle frame.
- the material that the shot pattern is initially applied to is particularly preferably a moist contact lens. It is particularly advantageous to select this contact lens in such a way that the sphero-cylindrical aberrations of the patient to be treated are already corrected with this lens. Only the previously measured higher aberrations on this contact lens can then be corrected with the treatment laser.
- the soft contact lens particularly advantageously has a refractive power and ablation property which largely corresponds to that of the comea.
- the shot positions of the provisional optical element will later correspond to the own optical element, in particular the Co ea.
- the provisional optical element in particular the contact lens, is advantageously aligned centrally and the reference axes of the wavefront measurement and the axis of the eye match.
- the use of materials such as PMMA as the ablation material of the provisional optical element is preferred.
- the different refractive index of both media is also taken into account, in addition to the differing depth of cut. Since these are constant factors, they can be mathematically very well recorded and transformed.
- a lens is preferably provided on a frame, so that no contact of this lens with the eye is required.
- the (provisional) lens is particularly preferably produced during the measurement of the wavefront in the optical system.
- the provisional lens is preferably processed iteratively and then the wavefront is measured again until no aberration of the overall system can be determined.
- One is particularly preferred such a procedure fixes the patient's eye, for example with a crosshair.
- glasses are produced for this purpose, which have outer and inner spherical surfaces, with at least one of these surfaces additionally having patterns applied, the transfer function of which is phase-conjugated with the uneven distortions of the wavefront which have been caused by the optical system or the eye. This makes it possible to make these specially determined corrections with such glasses.
- the average values of the emmetropia and the wavefront of the eye are determined, the radii of the outer and inner surfaces are calculated, which represent a correction of these average values of the emmetropia, and at least one of the surfaces with radii of curvature is produced have been changed in the order of the maximum deviation of the wavefront from the emmetropia corrected by the previous step and then this deviation of the surface will correspond to Patterns of the irregular distortions of the wavefront of the optical system or the eye are used.
- these surface irregularities are applied to the surface either by material removal or material application.
- This removal can be done by laser radiation, thermal or athermal processes, e.g. done by ablation.
- the application to the surface can be done in layers.
- the surfaces in the different sectors are particularly preferably adapted precisely to the eye, so that, for example, two areas can arise in which the compensation can be selected as a function of the accommodation state of the eye if the eye uses the corresponding area.
- the surfaces are particularly preferably changed such that the geometric shift of the plane of the glasses is also compensated for by the basic plane of the optical system of the eye.
- the object is achieved by an ideal optical system which was produced by a method according to the invention and / or by means of a device according to the invention, the optical system comprising elements made of materials suitable for implantation and / or adhesion and / or suitable for ablation, in particular plastic or glass.
- the optical system comprising elements made of materials suitable for implantation and / or adhesion and / or suitable for ablation, in particular plastic or glass.
- an ideal optical system which comprises elements which comprise refractive and / or diffractive structures.
- Refractive and / or diffractive structures have so far only been used in beam shaping.
- a mini lens system directs and shapes the incoming beam in order to achieve a special beam distribution in the target plane.
- refractive and or diffractive stem structures on individual elements of an optical system allows the targeted correction of poor eyesight in an unusually ideal manner.
- the use of these structures makes it possible to correct individual non-continuous aberrations or to give the optical systems properties that a normal human eye does not have.
- the object of the invention is further achieved by an element of an (ideal) lens system which has refractive and / or diffractive structures.
- Such elements can be intraocular lenses, modified corneas, contact lenses, ICL's or spectacle lenses.

- spherical aberration can be corrected with the first optical element and one with the second optical element
- Astigmatism can be compensated and a coma can be compensated with the third optical element.
- the individual optical elements can be processed one after the other with the shot positions determined by the correction parameters and individually reshaped.
- a vision test is preferably carried out after each (partial) correction so that the change can also be subjectively checked.
- FIG. 2 b shows how a superposition of all errors on an optical element would work and how the compensation indicated above in the lower case would have to be transferred to an optical element or would be transferred at the end.
- a device and a method for correcting visual defects in the human eye which elegantly allow a complete correction of all refractive visual defects, including the aberrations of the beam path in the defective eye, the individual errors also being preferred by iterative correction can be carried out in advance on one or more provisional optical elements and can be assessed by the viewer without any intervention on the eye.
