Abstract
Description
[0001] Method and arrangement for producing an ophthalmological device
[0002] The invention relates to a method and an arrangement for producing an ophthalmological device.
[0003] Ophthalmic devices, such as intraocular lenses, are traditionally manufactured primarily by turning. For this purpose, the starting material is first produced by polymerization. Blanks are then cut from the starting material. For hydrophilic intraocular lenses, the blanks are attached to a lathe using wax; for hydrophobic intraocular lenses, the blanks are frozen, particularly at around -20°C. A computer-controlled robot arm equipped with a diamond tip machines the intraocular lens, for example, from the blank rotating in the lathe. However, this is a complex and cost-intensive process. Another disadvantage is that a diamond tip used in turning leaves grooves on the surface of the ophthalmic device, which impair the optical quality of the ophthalmic device.
[0004] DE 102020 108 375 B3 discloses a method for producing an intraocular lens by tomographic printing. The method comprises the steps of: providing a container transparent to electromagnetic radiation, in which a liquid is arranged that can be cured with the electromagnetic radiation; irradiating the liquid with a set of images formed by the electromagnetic radiation, each of which shows an intraocular lens, wherein each of the images of the set is irradiated into the liquid at a different angle of incidence with respect to a reference plane passing through the liquid, whereby the liquid is cured and the cured liquid forms the intraocular lens, wherein an actuator, a solar module and / or a sensor is arranged in the liquid and the intraocular lens is formed around the actuator, the solar module and / or the sensor.
[0005] From WO 2019 / 043529 A1 a method for producing a three-dimensional object is known, comprising calculating a sequence of backprojections describing the three-dimensional object to be formed from different orientation angles of the object, defining a sequence of light patterns using the backprojections and irradiating a photoresponsive material capable of changing its material phase upon irradiation with light with each of the light patterns at the respective corresponding orientation angle and according to the defined sequence, thereby generating a three-dimensional distribution of changes within the photoresponsive medium that physically reproduces the three-dimensional object, thereby generating the three-dimensional object.
[0006] The invention is based on the object of improving a method and an arrangement for producing an ophthalmological device.
[0007] The object is achieved according to the invention by a method having the features of patent claim 1 and an arrangement having the features of patent claim 10. Advantageous embodiments of the invention emerge from the subclaims.
[0008] One of the basic ideas of the invention is to produce an ophthalmological device with at least one first partial piece and at least one second partial piece. The at least one first partial piece is provided, while the at least one second partial piece is printed tomographically. This allows the ophthalmological device to be produced in such a way that at least one second partial piece is arranged on the at least one first partial piece and / or at least partially encloses it. This allows the at least one first partial piece to be at least partially integrated into the at least one second partial piece. For this purpose, it is provided that the at least one first partial piece is provided, wherein the at least one first partial piece can in principle be produced using any desired manufacturing method.The at least one first section is arranged by means of at least one holding device in a container transparent to electromagnetic radiation and is held in position and / or orientation there by the at least one holding device. The at least one second section of the ophthalmic device is then tomographically printed. For this purpose, a data set comprising images of the second section of the ophthalmic device is generated and / or provided for each second section (if several are to be produced), wherein the images contain projections of this at least one second section from different directions. A liquid curable by means of electromagnetic radiation, which is provided in the container, is then tomographically printed based on the generated and / or provided data set to form the at least one second section.The generation and / or provision of the data set and the tomographic printing are carried out in such a way that at least one second partial piece is arranged on the at least one first partial piece and / or at least partially encloses it.
[0009] In particular, a method for producing an ophthalmic device is provided, comprising: providing a container transparent to electromagnetic radiation, providing at least a first portion of the ophthalmic device, securing the at least one first portion in the container by means of at least one holding device, and for at least a second portion of the ophthalmic device:
[0010] - Providing a liquid that can be cured by means of electromagnetic radiation in the container,
[0011] - generating and / or providing a data set of images of the second portion of the ophthalmic device, wherein the images include projections of this second portion from different directions,
[0012] - tomographic printing of the curable liquid by means of electromagnetic radiation starting from the generated and / or provided data set to form this second partial piece, wherein the generation and / or provision of the data set and the tomographic printing are carried out in such a way that at least one second partial piece is arranged on the at least one first partial piece and / or at least partially encloses it.
[0013] Furthermore, in particular, an arrangement for producing an ophthalmic device is provided, comprising a container transparent to electromagnetic radiation, at least one holding device, a data processing device and a tomographic printing device, wherein the at least one holding device is designed so that at least one provided first part of the ophthalmic device can be fastened in the container, wherein the data processing device is designed to generate and / or provide a data set from images of at least one second part of the ophthalmic device, wherein the images contain projections of this at least one second part from different directions, wherein the tomographic printing device is designed toto tomographically print a liquid curable by means of electromagnetic radiation contained in the container by means of electromagnetic radiation starting from the generated and / or provided data set to form the at least one second partial section, wherein the generation and / or provision of the data set and the tomographic printing are carried out in such a way that at least one second partial section is arranged on the at least one first partial section and / or at least partially encloses it.
[0014] The advantage of the method and arrangement is that, in principle, any materials can be combined. For example, the first part can be a haptic element of an intraocular lens, and the second part can form an optic of the intraocular lens. The material of the first part can, in principle, be selected from almost any material and / or manufactured in any way.
[0015] The electromagnetic radiation lies in particular in the optical wavelength range, in particular in the visible and / or UV wavelength range. The curable liquid can in particular have the properties described in DE 102020 108 375 B3. In particular, tomographic printing is generally carried out in the manner described in DE 10 2020 108 375 B3. The images of the data set can be calculated for generation and / or provision, for example, from a three-dimensional data set (e.g. CAD data) which contains the shape of the ophthalmic device, in particular of the at least one second portion. This is in particular a reverse process to that used in tomographic imaging. Tomographic imaging is used, for example, in computed tomography. Tomographic imaging can, for example, make use of a Radon transformation.Tomographic printing makes particular use of this reverse process to locally cure the curable liquid using the calculated images depending on the light patterns contained in the images of the data set.
[0016] The curable liquid comprises, in particular, a solution with a dissolved monomer and a photoinitiator, which can trigger polymerization of the monomer in a radiation-dependent manner. Furthermore, other substances can also be part of the curable liquid, such as fillers, optically excitable dyes or nanoparticles, and / or medicinal agents. In particular, it is intended that the curable liquid has a specified minimum viscosity of at least 100 mPa*s (cps).
[0017] The ophthalmic device may be an intraocular lens. The intraocular lens may also be an accommodating intraocular lens. The ophthalmic device, in particular the intraocular lens, may also have, as a first component, an actuator, a solar module, and / or a sensor. Furthermore, the ophthalmic device, in particular the intraocular lens, may comprise an optical body and at least one haptic.

[0019] It may be provided that the ophthalmic device manufactured according to the method is subsequently post-processed, for example by turning, mechanical polishing, laser polishing and / or laser cutting, etc.
[0020] Parts of the arrangement, in particular the data processing device, can be implemented individually or collectively as a combination of hardware and software, for example as program code executed on a microcontroller or microprocessor. However, it can also be provided that parts are implemented individually or collectively as an application-specific integrated circuit (ASIC) and / or a field-programmable gate array (FPGA).

This can improve a mechanical connection between the at least one first section and the at least one second section, in particular by form-fitting. This can in particular prevent the at least one first section from becoming detached from the at least one second section. The anchor can, for example, have arms extending laterally from a web, which make it difficult or impossible for the web to move out of the second section.
[0022] In one embodiment, it is provided that the at least one holding device is or will be arranged on a closure device for the container, wherein the closure device is arranged on the container together with the at least one holding device and the at least one first section arranged thereon.

The at least one actuator is controlled and / or regulated, in particular, by the data processing device.
[0026] In one embodiment, it is provided that the at least one first section is arranged on the at least one holding device by means of a retaining clip. This makes it possible to provide a particularly easy-to-handle fastening. It can be provided that the retaining clip has a negative mold of at least a partial region of the at least one first section, into which, when the retaining clip is open, the at least one first section can be inserted and thus brought into position and / or orientation and / or held in a closed position of the retaining clip.
[0027] In one embodiment, it is provided that the at least one first section is or is fastened to the holding device by means of at least one thread and / or at least one wire and / or at least one fiber and / or at least one holding arm.
