Eye surgery surgical system having an oct device and computer program and computer-implemented method for continuously ascertaining a relative position of a surgery object

An eye surgery surgical system comprising:

• a visualization device for displaying a relative position of a section of a surgery object in a 3D reconstruction of a region of a patient's eye;
• at least one device for continuously providing at least two data records relating to overlap regions in a form of at least partly overlapping portions of the region of the patient's eye and of the section of the surgery object to a computer unit;
• a computer program for continuously ascertaining the relative position of the section of the surgery object and continuously ascertaining the 3D reconstruction of the patient's eye from the at least two data records provided, wherein the computer program is stored on a non-transitory computer readable medium of the computer unit;
• the computer program including a first program routine configured, when executed by a processor, to continuously ascertain the relative position of the section of the surgery object and the 3D reconstruction of the region of the patient's eye from the at least two data records provided via a registration method and including a second program routine configured to adapt the registration method on the basis of a criterion;
• and,
• wherein
• the criterion takes account of properties of at least one of the data records, the region of the patient's eye, the surgery object, the eye surgery surgical system, the registration method, a currently ascertained registration, and a type of surgery.

• and,
• wherein
• the criterion takes account of the availability of at least one of the data records, quality features of the region of the patient's eye in a form of a type or quality of tissue or material in the region, a size of the region, a type of surgery, quality features of the surgery object in a form of dimensions or material properties thereof, quality features of devices of the eye surgery surgical system in a form of settings of the eye surgery surgical system or properties of individual components or of an illumination setting, properties of the registration method in the form of its suitability for the data records present or the speed or accuracy thereof, and quality of a currently ascertained registration.

A computer program for continuously ascertaining a relative position of a section of a surgery object and continuously ascertaining a 3D reconstruction of a region of a patient's eye from at least two data records provided, which relate to overlap regions in the form of at least partly overlapping portions of the region of the patient's eye and of the section of the surgery object, the computer program comprising:

• program code stored on a non-transitory computer readable medium, wherein said program code is configured, when executed by a processor, to ascertain the relative position of the section of the surgery object and of the 3D reconstruction of the region of the patient's eye via a registration method which is adapted on the basis of a criterion;
• wherein the criterion takes account of at least one of an availability of the data records, quality features of the region of the patient's eye in a form of a type or quality of tissue or material in the region, a size of the region, a type or surgery, quality features of the surgery object in a form of dimensions or material properties thereof, quality features of devices of the eye surgery surgical system in a form of settings of the eye surgery surgical system or properties of individual components or of an illumination setting, properties of the registration method in a form of its suitability for the data records present or the speed or accuracy thereof, and quality of the currently ascertained registration.

A computer-implemented method for continuously ascertaining a relative position of a section of a surgery object and continuously ascertaining a 3D reconstruction of a region of a patient's eye from at least two data records provided, which relate to overlap regions in the form of at least partly overlapping portions of the region of the patient's eye and of the section of the surgery object, via a computer program stored on a non-transitory computer readable storage medium, the computer implemented method comprising:

• ascertaining the relative position of the section of the surgery object and of the 3D reconstruction of the region of the patient's eye via a registration method which is adapted on the basis of a criterion;
• and,
• wherein the criterion is one of a first criterion, a second criterion and a third criterion;
• wherein the first criterion is at least one characteristic of the data records from measurement accuracy of the data records, number of data records, type of data records, and type or number of different modalities of the data records,
• wherein the second criterion takes account of at least one of properties of the data records, the region of the patient's eye, the surgery object, the eye surgery surgical system, the registration method, a currently ascertained registration, and a type of surgery;
• and,
• wherein the third criterion takes account of at least one of an availability of the data records, quality features of the region of the patient's eye in a form of a type or quality of tissue or material in the region, a size of the region, a type or surgery, quality features of the surgery object in a form of dimensions or material properties thereof, quality features of devices of the eye surgery surgical system in a form of settings of the eye surgery surgical system or properties of individual components or of an illumination setting, properties of the registration method in a form of its suitability for the data records present or the speed or accuracy thereof, and quality of the currently ascertained registration.
