Abstract
This invention relates to a method and a device for the complete correction of sight defects in the human eye. Combinations of measuring, and processing methods are described which when applied as disclosed in the invention, make it possible to fully correct sight defects in the human eye. Measuring methods are used which can precisely scan the surface of the cornea and also register other imaging defects in the light path up to the retina. Computer-aided of said measuring results determined when combined with calculation of ideally corrected ocular lenses (for example after cataract operations) or ideally corrected surfaces of the cornea opens up the possibility of manufacturing a patient-specific lens and/or achieving ideal correction of the cornea using preferably a topography-supported spot-scanning-excimer laser system.
