An accommodative intraocular lens includes a first lens part, a haptic, and a flexible membrane. The flexible membrane is arranged adjacent to a distal optical body surface, delimits a cavity together with the distal optical body surface and is transparent to light. A second lens part has a hollow cylinder coupled releasably to the first lens part, as a result of which the intraocular lens can be brought into a coupling state in which the second lens part is arranged on a distal side of the first lens part and the hollow cylinder is configured to deform the membrane by a longitudinal displacement of the hollow cylinder parallel to the optical axis. The hollow cylinder has on its exterior an outer face and a bearing face arranged adjacent to a proximal end of the outer face and encloses, with the outer face, an angle of less than 180°.

Accommodative intraocular lens

An accommodative intraocular lens is for insertion in the capsular bag of an eye. The accommodative intraocular lens has a first lens part, including a first membrane and an optical axis, and a second lens part which can be detachably coupled to the first lens part, whereby the intraocular lens can be transferred to a coupled state.

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.

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.
