The invention relates to a contact glass for ophthalmic surgery. Said glass comprises a lens body that is held in a frame and a front lens surface that is designed to be placed against the eye. According to the invention, the front lens surface is concave and follows a surface curvature (K) and an annular gap is formed at the edge of the front lens surface between the lens body and the frame, said gap being used to apply a negative pressure in order to fix the contact glass to the eye. The frame is designed to follow the contour of an imaginary continuation of the surface curvature (K), or at least does not project beyond the latter.

The invention refers to a system to treat and/or diagnose a patient's eye. The system in this invention comprises several devices for the treatment and/or diagnosis of the eye as well as means for the logical linking of the devices with each other, such as systems for the spatial positioning of the devices relative to each other, configurations for the positioning of the patient and the eye to be treated relative to the respective devices, systems for the controlled supply of the devices with power and auxiliary power, and/or notification tools to transmit information or control commands between the above-mentioned devices, units, configurations and systems, and to put out information.

An adapter for mechanically coupling a laser processing device to an object. The adapter has a central region which can be moved into the beam path of the laser processing device and a peripheral region located outside the central region. The beam path extends up to the object along an optical axis. The adapter is fixable to the laser processing device on the one hand and provided so as to contact the object with its central region on the other hand. A fixture is provided at the peripheral region that allows the adapter to be releasably fixed to a receiving part of the laser processing device such that, upon application of a determined pulling force along the optical axis, the The fixture is removable from the receiving part.

An adapter to be applied in contact with an anterior corneal surface. The adapter includes a contact glass portion having a corneal contact surface curvature that is flatter than the undeformed anterior corneal surface. When the contact glass is applied the cornea assumes a deformed state corneal curvature that is parallel to the flatter corneal contact surface curvature. A mount portion circumferentially surrounds the contact glass portion and defines a suction duct that is structured to secure the adapter to the cornea by negative pressure when the suction duct is brought into contact with a surface of the eye surrounding the contact glass portion. The suction duct is partially defined by a peripheral edge of the mount that extends outwardly away from the mount portion and toward but not intersecting or extending beyond a geometric continuation of the corneal contact surface curvature.

摘要:
The invention relates to an adapter for coupling a laser treatment device to an object for treatment, whereby the adapter has an input side, which may be fixed relative to the laser treatment device, by a locking mechanism and which may be fixed to the object, for alignment of the object relative to the laser treatment device. A scanned laser beam is introduced on the input side, from the laser treatment device, along a beam path to the object with a reference structure. The reference structure lies on the beam path of the adapter and may be optically detected by means of the laser beam scanned over the region.
