The invention relates to an operation system for supporting microsurgery operations, e.g., operations through which the natural crystalline lens is replaced by an artificial intraocular lens. The operation system comprises several surgical instruments ( ) which are inserted into a receptacle ( ), where they are connected to a connection tube ( ), e.g., lines for liquids ( ) and/or electrical lines ( ). The receptacle ( ) for a surgical instrument can be docked on a supply unit ( ) on which several connections for the supply of the corresponding surgical instruments are provided at various connection points. A control unit ( ) recognizes by means of a decoding connection ( ) which surgical instrument ( ) is connected in its receptacle to the supply unit.

Surgical operation system

Intraoccular lens arrangement and method for correcting astigmatism

A cannula for an eye-surgery instrument, employed to shatter the lens of the eye by high-frequency oscillation and to suction out the fragments. It accommodates a suction channel with a section that is wider toward the tip of the cannula. The wider section (20) comprises at least two straight bores (8, 9, & 10), one wider than another, extending coaxial with the suction channel (7) into the cannula (1) from its tip (5). Fragments of the shattered lens accumulate in the bores in accordance with size, where they can be further fragmented by ultrasound.
