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

[0275] figure 1 A schematic diagram showing a physiological and physical model of a spectacle lens and an eye in a predetermined wearing position and an exemplary beam path on which a single spectacle lens calculation or optimization according to a preferred embodiment of the invention is based.

[0276] Here, preferably only a single ray (principal ray 10, which preferably passes through the center of rotation Z' of the eye) is calculated for each viewpoint of the spectacle lens, but also the derivative of the wavefront's apex depth lateral coordinate (vertical on the chief ray). These derivatives are taken into account to the desired order, with second derivatives describing the local curvature properties of the wavefront and higher derivatives being related to higher order aberrations.

[0277] When the light rays are traced to the eye 12 through the spectacle lens according to the separately provided eye model, the local derivatives of the wavefronts are eventually identi...

Abstract

The invention relates to a method, a device and a corresponding computer program product for optimizing a spectacle lens of a wearer of an implantable intraocular lens. Here, the method comprises the steps of:-providing individual refractive data of the at least one eye of the spectacle wearer; defining an individual eye model wherein at least the following are defined as parameters of the individual eye model:-the shape and / or diopter of the cornea of the model eye (12), in particular the shape and / or diopter of the corneal anterior surface (18); -the cornea-lens distance; -parameters of the crystalline lens of the model eye; -the distance from the lens to the retina. Here, the parameters defining the individual eye model are performed on the basis of vision correction data of the at least one eye having the intraocular lens and further on the basis of individual measurements and / or standard values of the eye of the eyewear wearer and / or on the basis of provided individual refractive data, such that the model eye (12) has the provided individual refractive 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 a spectacle lens of at least one eye of a spectacle wearer, and to a method for use in A corresponding method, device and computer program product for calculating (optimizing) and manufacturing spectacle lenses with the help of partly individual eye models. Here, 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, instead of or in addition to the natural eye lens. In other words, spectacle wearers are wearers of implanted intraocular lenses. Furthermore, the invention relates to a method, a device and a corresponding computer program product for calculating (optimizing) and manufacturing spectacle lenses, in particular sp...
