Embodiment Construction

[0028] First refer to figure 1 . The operating table shown therein is provided with: hospital bed (couch) 10, such as figure 1As shown, lying on a hospital bed is a patient 12 , shown only schematically, who has an eye 14 to be treated; An incision is made in the tissue. The laser system 16 includes a laser source 20 that is arranged on a support frame 18 (eg, in the form of a shelf or table) and that includes, for example, a solid-state laser or a fiber laser and provides pulsed laser radiation. The laser radiation emitted by the laser source 20 is coupled into a flexible delivery fiber 22 through which the laser radiation is transmitted to a laser treatment head 26 which is held on a support 24 and from which laser radiation is applied to the patient's eye 14 . The laser radiation emitted by the laser therapy head 26 has radiation properties suitable for generating photodisruption in the tissue of the patient's eye 14 . For example, the pulse width of the applied laser ...

Abstract

There is proposed an apparatus for eye surgery, which comprises a stand (24) having a stand base (32) that is movable or realized for mounting on a wall or ceiling, and having a stand arm arrangement (34, 36) that is manually adjustable, at least partially, relative to the stand base, an operation microscope (38) being attached to the stand arm arrangement. Further, the eye-surgery apparatus comprises a laser appliance, which provides pulsed, focused laser radiation having radiation properties suited to the application of incisions in the human eye (14). The laser appliance comprises a laser source (20) and a laser treatment head (26) that is attached to the stand arm arrangement (34, 36) and emits the laser radiation, a flexible transmission fiber (22) or a jointed beam transport arm being provided for the purpose of transporting the laser radiation to the laser treatment head. The laser treatment head (26) is positioned or positionable in an observation beam path of the operation microscope (38) and provides a passage (52) for an observation beam going along the observation beam path. According to one embodiment, the laser treatment head (26) can be moved out of a position of use, in which it is positioned over the eye (14) and under the operation microscope (38), into a non-use position, in which it is at a distance from the working region of the operating physician (40) and the latter, through the operation microscope (38), has a direct view of the eye (14) to be treated.

Description

technical field [0001] The present invention relates to laser-assisted surgery on the human eye, which includes the treatment of the eye by laser light and the performance of additional surgical tasks in a sterile environment. Background technique [0002] Laser-assisted cataract surgery (ie, the treatment of cataracts by implanting an intraocular lens in the eye) is an example of a form of surgery in which the laser is followed by the use of other surgical devices to complete the procedure. For example, in order to open the anterior capsule region of a person's eye (capsulorhexis) and create a lateral incision at the limbus so that the person's lens can be removed, the intraocular lens can be inserted and the instruments required for the situation introduced, one can use Laser to make the incision. A laser can also be used to pre-separate the phacoic intraocular lens, ie to divide it into segments so that the lens can be more easily dissolved and extracted by phacoemulsifi...
