Definitions
- the invention relates to a method for producing an optical lens which is individually adapted to a patient and to an optical lens produced by this method.
- the invention relates to IOL (intraocular lenses), RI (refractive implants, phakic and aphakic) implanted in the eye or cornea, CL (contact lenses) and also spectacle lenses (spectacles glass, SC).
- IOL intraocular lenses
- RI reffractive implants, phakic and aphakic
- CL contact lenses
- SC spectacle lenses
- Such lenses have hitherto been produced either by the reaction injection molding method (RIM) or by a UP turning process with a diamond tool.
- RIM reaction injection molding method
- UP turning process with a diamond tool.
- these methods do not make it possible to produce a customized lens individually tailored to a patient, since economic freedom can not achieve freedom of geometry.
- These methods are severely limited in terms of production, so that in practice only in rigid increments different parameters can be taken into account.
- surface polishing "Tumbler polishing" method by which even such rigid specifications are changed in unpredictable size.
- a method individually adapted to a patient is understood to be a method in which standard lenses of different dimensions are not produced for specific patient groups, but rather the data of a single patient are determined and a specific lens is produced for this data. This makes it possible to respond to different properties of the required lens and to correct various specific vision defects.
- EP 0 954 255 B1 proposes cutting an artificial lens from a blank by means of a laser. However, this process has not received any practical relevance since the application until today. [07] The invention is therefore based on the object of providing an economically feasible method and a lens produced therewith in order to make available to a large number of patients an individual lens optimally adapted to the respective visual defects and anatomical specifications.
- This object is achieved with a method for producing such an individualized on a patient optical lens, wherein the lens is made by a laser process constructive or disruptive.
- these lenses are individually tailored to the patient using various laser and printing techniques. This results in "Laser Customized IOL, CL and corneal Implants” or even individual lenses, as now also with eyeglass lenses individual production becomes possible.
- the method according to the invention enables the production (sculpturing and polishing by laser) of the tailored IOL and CL with all the parameters required. tern: diopters (to correct myopia and hyperopia), asphericity (to correct aberrations of the cornea), diameter and design of optics and haptics, inclination. Torizity (to correct astigmatism), Multifocal (to correct for presbyopia), Sharp edge (to avoid after-star). [12] Technically, this is possible if, for example, UV, C0 2 or UKP laser are used.
- a blank can be printed, which is subsequently reworked with the laser.
- SLM and SLS are preferable to the ablative procedure as generative methods, since these are more material-saving and easier to operate in logistics [17]. This can be done with an appropriate laser ablating, sculpting or generative with a 3D printer.
- Suitable materials include, for example, biocompatible polymers, as they are already used in medical technology, and also other optically and biologically suitable substances in question.
- the surfaces are then preferably laser-finished to achieve the required roughness for optimum optical imaging quality. It is advantageous if the laser used for lens production is also used for polishing. In particular, a C0 2 laser is suitable for this purpose.
- a preferred process for producing such lenses is described in WO 2012/1 19761 A1. In this method, the description of which is incorporated by reference in its entirety, a blank for the manufacture of an optical element by coarse material removal is processed by means of energetic radiation and then preferably polished without removal of material with energetic radiation and further treated after a survey until the desired target shape is reached.
- the surface can be produced so smoothly that, compared with natural lenses and known lenses, the risk of cell growth on the surface of the lens is greatly reduced.
- a particularly preferred embodiment provides that by introducing a special surface structure an increase of cells is further reduced.
- This surface structure is designed such that, in accordance with its precision and its location of application, it does not impair the optical properties of the lens in the visible light range. It has been shown that with such a Structure, the wetting of the structure is reduced with a liquid and thereby cell growth is reduced.
- such a structure on the surface can reduce the adhesion force between the surface and the particles lying on it and the liquid lying on them so much that self-cleaning occurs. The effect can be improved by applying wax to the structure.
- the structures are formed in such a way that the wavelengths influenced by the structures lie outside the visible light.
- structures are formed as 10 to 20 micrometer high and 10 to 15 micrometer apart elevations. Then hydrophobic waxes can be applied.
- the hydrophobicity of the surface of the lens can be increased in order to ensure a particularly smooth surface in the long term. This avoids that a particular optically optimal surface, which is present once for a new lens, is changed during use of the lens due to contamination or adhering material, so that the biocompatibility and the optical values change.
- the change of the structure of lens surfaces by micro- or nanostructuring, in particular for medical lenses as contact lenses or lenses for insertion into the human or animal eye, is also independent of the aforementioned features and in particular regardless of the mode of manufacture the lenses essential to the invention.
- the parameters for calculating the tailored lenses are provided by measuring human or animal eyes with state-of-the-art techniques such as IOL masters, wavefront-controlled topographies, Scheimpflug surveys, etc. on the laser and / or 3D printer.
- the data of a group of people can be determined.
- the data of a single individual eye is determined to provide a lens specifically for that eye.
- This lens can act as an exchange lens (IOL) or as a supporting lens, such as a contact lens.
- Suitable and easy-to-develop formulas translate these measurement results into instructions to the laser or 3D printer, which then make the customized optics erosive and / or generative.
- the following parameters can be considered: choice of material (hydrophobic, hydrophilic, etc.), diameter and design of the optic, diameter and design of the haptic, structure of the optic, structure of the haptic, inclination in IOL, dioptric value (+ / -) spherical, diopter (+ / -) cylindrical, mark the axis position and asphericity.
- the refractive index is determined by a suitable material.
- This also allows a multifocality with predeterminable focal points. For example, a musician may receive a different addition than a goldsmith.
- a selection of the material allows to determine the filtering effect of the material (eg UV protection).
- the IOL can be adapted to the size and position of the pupil. If necessary, it is possible for the examining doctor of the slit lamp to create a coding that becomes visible when the pupil is wide.
- the starting point for the production of the individualized lenses are the measurement methods Pupillometry 1, US Biomicroscopy (UBM) 2, various biometric methods 3, 4, 5, topography and wavefront detection 6 as well as individual specifications 7.
- UBM US Biomicroscopy
- These mean starting situation 8 is the basis for the following Materialaus election 9, determining the size of the optics 10 and determining the size and shape of the haptic 11, the diopter Sphere 12, the Diopter Tone 13, the inclination 14, the asphericity 15, the Multifocal 16 as well of marks and codes 17 and sharp edges.
