Problems solved by technology

Therefore, there are currently no lenses that are particularly suitable for patients with intraocular lenses
This means that the properties of the implanted intraocular lens cannot be taken into account, however the properties of the implanted lens are very different from those of the natural lens

Embodiment Construction

[0306] figure 1 A schematic diagram showing a spectacle lens and a physiological and physical model of the eye in a predetermined wearing position and an exemplary beam path upon which a single spectacle lens calculation or optimization according to a preferred embodiment of the present invention is based.

[0307] Here, preferably only a single ray (chief ray 10, which preferably passes through the eye rotation center Z') is calculated for each viewpoint of the spectacle lens, but also the derivative abscissa (vertical) of the vertex depth of the wavefront is calculated according to on the chief ray). These derivatives are taken into account to the desired order, the second derivative describes the local curvature properties of the wavefront, and higher derivatives are associated with higher order aberrations.

[0308] When rays are traced to the eye 12 through the spectacle lenses according to the separately provided eye model, the local derivatives of the wavefronts are fina...

Abstract

The present invention relates to a computer-implemented method for ascertaining relevant individual parameters of at least one eye of a spectacle wearer for the purposes of calculating or optimizing an ophthalmic lens for the at least one eye of the spectacle wearer, comprising the steps of: providing individual data of properties of the at least one eye of the spectacle wearer; constructing an individual eye model by defining a set of parameters of the individual eye model; and determining a probability distribution of values of the parameters of the individual eye model on the basis of the individual data.

Description

technical field [0001] The present invention relates to a method, a device and a corresponding computer program product for determining relevant individual parameters of at least one eye of a spectacle wearer for calculation or optimization of spectacle lenses of at least one eye of a spectacle wearer, and to a Corresponding method, apparatus and computer program product for the calculation (optimization) and manufacture of spectacle lenses with the help of partial individual eye models. In particular, at least one eye of the spectacle wearer has an implanted intraocular lens (IOL). For example, an intraocular lens may be implanted in at least one eye during surgery in place of or in addition to the natural eye lens. In other words, the spectacle wearer may in particular be the wearer of an implanted intraocular lens. Furthermore, the invention relates to a method, a device and a corresponding computer program product for the calculation (optimization) and manufacture of spe...
