Laser configuration that reduces the laser footprint and improves ergonomics

摘要

A laser system for eye surgery comprises a laser source for emitting a laser beam and a beam delivery means to direct the laser beam to a position where a patient's eye is located. The beam delivery means within a beam delivery arm is arranged at an angle ± with respect to the direction of the beam when emitted from the laser source. The angle ± is in a range of 105° to 165°, preferably in a range of 115° to 155°, and more preferably the angle ± is approximately 135°. The system may comprise a device body in which the laser source may be arranged. The beam delivery means may comprise a beam delivery arm extending to a position above the patient's eye. Preferably, the laser source is arranged to emit the laser beam in a direction from the head to the feet of the patient when being positioned for surgery. That is, the laser beam is emitted in a direction away from an operator of the device.
