20080287927 | Protective device for ophthalmic laser treatment - A protective device for ophthalmic laser treatment comprises a transparent foil for protecting an eye from direct contact by a reference body disposed between a laser applicator and the eye. The protective device further comprises means for disposing the foil between the reference body and the eye, for example a carrier frame, having the foil attached thereto, and a suction ring for attachment to the eye around an operative area. The suction ring is designed for receiving the carrier frame such that the operative area is covered by the foil when the suction ring is attached to the eye. Furthermore, the suction ring is provided with coupling means for attachment to the laser applicator. When the laser is activated, laser pulses are projected from the laser applicator through the reference body and the foil to dissolved tissue of the eye. By moving the focal point of the pulsed laser beam into the foil, open cuts can be made in the eye, without damaging the reference body. | 11-20-2008 |

20090294422 | Method and device for the removal of material by means of laser pulses - The invention relates to a method for removing material by means of a laser, wherein a sequence of laser pulses is generated and an area of material to be machined is irradiated with the sequence of laser pulses. Methods of this kind are used to cut a number of different materials. One problem with this method is that thermal or mechanical damage occurs in the surroundings of the area being machined and causes impairment of areas of material that are not being machined. The invention solves this problem by the pulse energy of a single pulse in the sequence of laser pulses being lower than the laser pulse energy required to produce material removal using an isolated laser pulse in the region irradiated with the single laser pulse of the sequence of laser pulses. | 12-03-2009 |
