Method of estimating a full shape of the crystalline lens from measurements taken by optic imaging techniques and method of estimating an intraocular lens position in a cataract surgery

A method of estimating a full shape of a crystalline lens from measurements of the lens taken by optical imaging techniques, the method comprises:

• a) estimating at least one weight coefficient from the measurements;
• b) applying a lens deformation pattern to each at least one weight coefficient to obtain a plurality of lengths of displacement, wherein the at least one lens deformation pattern is obtained from ex-vivo measurements;
• c) displacing a first plurality of points the plurality of lengths of displacement obtained in step b) to a location of a second plurality of estimated points of the full shape of a lens.

A data-processing system configured to determine a full shape of a crystalline lens by means of displacing a first plurality of points a plurality of lengths following a plurality of directions to a location of a second plurality of points, wherein

• the first plurality of points defines an initial full shape of a crystalline lens,
• the initial full shape is obtained from ex-vivo measurements, and the plurality of lengths is obtained by applying a weight coefficient to each of at least one lens deformation pattern.
