An eye surgery surgical system includes a visualization device for visualizing the position of at least one trocar point for a trocar on the sclera of a patient's eye. The trocar serves to introduce a surgical instrument configured for surgical interventions on the fundus of the patient's eye into the patient's eye. The eye surgery surgical system also includes a computer unit which is configured to provide the position of the at least one trocar point to the visualization device. Here, the computer unit contains a trocar point computation routine configured to calculate the position of the at least one trocar point from the location of at least one surgical site in a model of the patient's eye and from geometric data relating to at least one surgical instrument introducible into the patient's eye through the trocar.

A computer program product for controlling a laser-assisted eye treatment, configured to encode a system controller with a routine for planning the eye treatment, invention further relates to a laser-assisted eye treatment system including a laser treatment unit and a system controller, to a method for generating control data for a laser-assisted eye treatment system, to a planning method for a laser-assisted eye treatment and to an eye treatment method using a laser beam for treating a patient's eye. The invention provides systems and methods for a fast laser-assisted eye treatment of a patient's eye which improve the security and minimize the risk of a non-optimal eye treatment and enable sale eye treatment planning and a shortening of the critical phase of the eye treatment. Encoding a system controller by a routine for planning the eye treatment is strictly based on an anatomy of a patient's eye.

A therapeutic method can include receiving an initial astigmatism condition of an eye; receiving a target final astigmatism condition of the eye; generating, based on the initial and target final astigmatism conditions, an eye incision pattern by iterating through a plurality of potential corrective combinations; and cutting the eye based on the eye incision pattern. Each of the potential corrective combinations can be defined by one or more of: an intraocular lens selected from a plurality of intraocular lens options, an access incision selected from a plurality of access incision options, and an arcuate incision selected from a plurality of arcuate incision options.

An ophthalmological laser therapy device having a pulsed laser, a positioning system and a control system that produce incisions in a tissue of an eye, in particular for producing corneal access incisions and a corresponding method. The invention produces corneal access incisions having increased leak tightness under external influences. Compressive strength, and complex incision geometries can be realized. An ophthalmological laser therapy device has a control system which is programmed to vary the operating parameters of the laser system and/or of the positioning system on the basis of a local position of the focal volume of a laser beam in the corneal tissue such that the access incision in the corneal tissue is varied and/or interrupted in the width of the access incision. The invention further includes a corresponding computer program product and a method for performing a corneal access incision in a corneal tissue of an eye.

Ophthalmic instrument

A method for detecting refractive errors in the eye that are attributable to a suboptimal surface shape of the front surface and/or rear surface of the cornea. An OCT volume scan and/or one or more OCT line scans of the front eye section are carried out; using the measured values, the front and rear surface of the cornea are detected by an edge detection process; the topography of the front and rear surface of the cornea are determined; and refractive errors are determined from said topographies.

A method for carrying out eye surgery comprises a comparison of images recorded before surgery with images recorded during surgery in order to generate a marker which represents a target orientation of an intraocular lens or a difference between a current orientation and the target orientation of the intraocular lens. An eye surgery system respectively comprises an imaging system which is used during a surgery and has a camera, and a diagnostic system which is used before surgery and which also has a camera. The imaging system used during surgery comprises an image processing device in order to perform a computation based on the recorded images, and in order to determine a respective orientation value, from which a representation of a marker representing the target orientation of the intraocular lens is obtained.

A surgical microscopy system having an illumination system is provided. The illumination system comprises a xenon gas discharge lamp and a spectral filter which is optionally positionable into an illumination beam path of the surgical microscopy system and removable from the same.

Thus, the illumination system is enabled to provide light having two different spectral characteristics which is advantageous in particular for imaging structures in the human eye scattering to a different degree.
