Abstract
Systems and methods for localizing intraocular lens and/or existing refractive index patterns, to laser write-patterns, and to refractive index patterns in order to modify the refractive index by application of femtosecond laser pulses. OCT-based confocal detection and sectional image systems are provided for localization purposes, the systems being particularly suitable for the detection of phase patterns in addition to the localization of the IOL. With respect to laser write-patterns, the modification of existing refractive index patterns in the IOL is carried out by destroying existing structures or supplementing existing refractive index patterns.
