Abstract: There is now provided a method for determining vision defects and for collecting data for correcting vision defects of the eye. The method comprises projecting an image into the eye of the patient with an adaptive optical system having adaptive optical elements.

Abstract: The invention relates to a method and to a device for completely correcting visual defects of the human eye. The invention mentions combinations of measuring and treatment methods that allow the complete correction of defects of the human eye if applied according to the invention. Measuring methods are used that precisely detect the surface of the cornea and that also register the aberrations that occur in the beam path up to the retina. The computer-assisted evaluation of these measurement results combined with the calculation of optimally corrected lenses (for example after a cataract operation) or of optimally correcting cornea surfaces makes it possible to produce a patient-specific lens and/or to shape the retina so that it optimally corrects the aberration. To this end, the invention preferably uses a spot scanning excimer laser system and makes use of the topography of the eye.

Abstract: To produce hollow articles of a thermoplastic by extrusion blowing a parison is transferred from the extruder die into the blow mold by means of a gripper device comprising two gripper arms which work hand-over-hand, alternatively grip the parison as it issues from the die and draw it at an adjustable take-off speed, which is greater than the speed of extrusion, into a blow mold waiting under the die, and the blow mold, after the gripper arm has passed the lower edge of the mold, closes about the parison still hanging from the die, the second gripper arm grips the parison just above the blow mold before the parison is severed between the upper edge of the mold and the gripper arm, the filled blow mold makes room for the next blow mold, the parison inserted in the mold is inflated in a manner which is in itself known to form the hollow body, the latter is released from the mold, and the entire sequence is repeated as a continuous set of cycles.
