- the optical properties of the artificial lens are determined prior to the operation, and the artificial lens is either made from the obtained optical data or selected from a supply of artificial lenses based on the obtained optical data.
- the determination of the optical data of the artificial lens is carried out on the basis of an eye examination in which characteristic data of the eye to be operated, such as the curvature of the anterior surface of the cornea, the length of the eye and others are determined. From the geometric data of the eye to be operated then the optical data of the artificial lens are determined so that the natural vision of the eye is given after insertion of the artificial lens and the patient as possible glasses or only a pair of low-strength
- the astigmatic property can be characterized for example by two different refractive powers in mutually orthogonal directions and an orientation of an axis with respect to, for example, the horizontal or the horizontal axis of the head.

- a display device of an eye surgery system generates a Representation of an eye and a representation of a marker, wherein the marker is displayed in dependence on an orientation value, which was determined by an image processing device.
- the display can be made by the display device such that the representation of the eye and the representation of the mark are made in a superimposed representation.
- the image processing device is configured to determine the orientation value from a first image and a second image.
- the determination can comprise a calculation of the two images with one another, such as a comparison of the first image with the second image. The first image was taken earlier than the second image.
- the recording of the second image may take place immediately before the display of the eye together with the marking, while the recording of the first image may take place half an hour or several hours or several days before the recording of the second image.
- the eye surgery system may have an image memory for storing the first image.
- the eye surgery system may also include an image memory for storing the second image.
- an ophthalmic surgery system includes an imaging system, which in practice may be similar, for example, to a conventional surgical microscope, the imaging system comprising: a
- Data memory for an orientation value, an image memory for a preoperatively recorded first image of an eye to be operated, a camera for intraoperative recording of a second image of the eye to be operated on, a
- An image processing device configured to obtain an orientation value from the first image and the second image, and a display device for generating a representation of the eye and a representation of a mark in FIG
- an imaging system comprises a tripod for holding a camera at a distance from the eye to be operated, wherein the stand comprises a plurality of joints, which allow a displacement of the camera in three mutually orthogonal spatial directions.
- the camera which takes pictures of the eye to be operated on, can be positioned by the surgeon or a helper so that it is favorable for the surgeon and corresponds to the position of the patient.
- the imaging system may include, for example, a surgical microscope, which may comprise, for example, one, two or more objectives and one or more individual eyepieces or pairs of eyepieces.
- the camera can be arranged in a beam path of the surgical microscope, and receive, for example, light for generating an image of the eye, which has passed through an objective of the microscope.
- the display device may comprise an image projector in order to display a representation of the marking in the beam path to the eyepiece.
- the display device may comprise a head-mounted display ("head-mounted display”) and / or a monitor carried by a console or a tripod.
- head-mounted display a head-mounted display
- monitor carried by a console or a tripod.
- the display device may have an interface which is input for inputting the first image, ie the image which was taken some time before the second image, so that an image processing device can process this input first image.
- the ophthalmic surgery system includes a diagnostic system which may be separately formed by the imaging system.
- the diagnostic system comprises a camera for capturing the first image of the eye to be operated and an interface for outputting the first image, in particular in such a format that it is immediately suitable for input to the input device and for processing by its image processing device.
- the diagnostic system is further configured to measure geometry parameters of the eye to be operated on and to provide the corresponding measurement data such that the optical data of an artificial lens suitable for insertion into the eye examined by the diagnostic system can be calculated therefrom , This calculation can be carried out using formulas which have been obtained empirically, wherein the calculations can be carried out with such a formula, in particular computer-aided.
- the diagnostic system directly outputs the optical data of the artificial lens.
- This data preferably includes an orientation value representing a desired orientation of the artificial lens relative to the eye.
- a method of preparing an eye operation comprising: taking a first image of an eye of a patient, taking a second image of the eye, providing a representation of the eye, determining an orientation relating to the representation of the eye based on the captured first image and the captured second image, and generating a representation of a marker as a function of the determined orientation and in superposition with the representation of the eye.
- the marker may indicate an orientation under which an artificial lens to be later inserted into the eye is to be oriented in order to achieve a good vision of the eye with the inserted artificial lens. Since the orientation is determined inter alia from the first image of the eye, which was taken before the acquisition of the second image, the artificial lens can later be oriented with a comparatively high accuracy. In fact, it is possible for the eye to be twisted relative to its normal position when the second image is received in the eye socket of the patient, and therefore determination of the orientation based solely on the second image would lead to a non-optimal orientation. For example, such a twist may be caused by a manipulation of the eye.
- this twisting may be caused by an effect called “cyclotorsion”, according to which a human eye can twist in the eye socket by up to 10 ° when the human goes from a sitting position to a lying position.
- cyclotorsion an effect called "cyclotorsion"
- the size and amount of this twist varies from patient to patient, making it difficult to predict.
- this effect is of importance when the pre-operative measurement of the eye takes place in an upright position of the patient's head and the acquisition of the second image and the subsequent orientation of the artificial lens in a lying position of the head.
- the determination of the orientation from the first image and the second image can be carried out in particular by an image comparison, which is based on structures of the sclera of the eye, such as structures of blood vessels. Frequently, structures of the iris of the eye are not available for such a comparison, since the iris was usually expanded by medication at the time of taking the second image, so that it is visible only to a very limited extent in the second image. However, it is possible to locate other structures of the eye that are visible in the sclera, such as blood vessels, with sufficient quality in the images so that image comparison based on these localized structures will make the orientation of the eye in the second image relatively relative to the orientation of the eye in the first image allows.
- the camera of the diagnostic system may comprise a larger number of pixels than the camera of the imaging system.
- an optical filter in an optical path to the camera, which captures the first image and in a beam path to a camera, which receives the second image, an optical filter may be provided which selectively acts on the spectrum of the light used to generate the images .
- the filter may be an infrared filter which transmits only infrared light, for example light of a wavelength greater than 800 nm, or the filter may be a bandpass filter tuned to an emission spectrum of a fluorescent dye.
- the camera may be an infrared camera or another for certain wavelength ranges selectively sensitive camera, in which a corresponding filter is already integrated.
- the above-described method for preparing an eye operation is free of steps that violate the integrity of the human body of the patient, so that this method does not necessarily have to be performed by a surgeon but rather by an assistant, which the patient on the intervention by the Surgeons prepared, can be performed.
- a method of performing an ocular operation which may include, for example, removing the natural lens from the eye.
- this method also includes insertion an artificial lens into the eye and orienting the artificial lens relative to the eye.
- a mark can be applied to the eye, for example in a region of the sclera, which is visible in the recorded first image and which remains on the eye for at least a limited time until the second image is taken.
- This mark can be used in the image comparison between the first image and the second image to determine the relative orientation of the eye in the two images. This can be particularly helpful when natural structures, such as blood vessels in the sclera, are not clearly visible in the images.
- the marker may be attached to the sclera as a groove or the like with a knife.
- it is possible to apply the label with a dye to the eye which dye may be biodegradable, so that it is no longer visible after a few hours or days, for example.
