Device for selecting contact lens within a furniture arranged to receive a plurality of contact lens and method associated thereof

Abstract

The invention relates to a device for selecting contact lenses within a cabinet arranged to receive a plurality of contact lenses, the device including a storage data device for storing data based on measurements from an auto refractometer; and a data processor device associated with a calculation module for identifying a contact lens on the basis firstly of data from the auto refractometer as previously stored in the storage device, and secondly of additional data relating to the contact lens that is to be identified and that was previously input by the user, the data processor device associated with said calculation module also being arranged to identify the location of the lens within the cabinet. The invention also relates to an associated method.

1 . A device for selecting contact lenses within a cabinet, the device comprising:
 a cabinet arranged to receive a plurality of contact lenses that are extractable from said cabinet;   means for storing data based on measurements from an auto refractometer; and
 data processor means associated with a calculation module for identifying a contact lens on the basis firstly of data from the auto refractometer as previously stored in the storage means, and secondly of additional data relating to the contact lens that is to be identified and that was previously input by the user, said data processor means associated with said calculation module also being arranged to identify the location of the lens within the cabinet so that said lens can be extracted from the cabinet. 
   
     
     
         2 . A device according to  claim 1 , wherein the device includes means for identifying information relating to the content of a box including a contact lens in the identified location in the cabinet, which means are associated with a module for taking account of this data within the device. 
     
     
         3 . A device according to  claim 2 , wherein the device comprises:
 remote transmission means for taking information relating to the contact lens for which the box has been identified and transmitting it remotely; and   a remote computer server capable of communicating with the transmission means for remotely transmitting the information relating to the contact lens, the server being arranged to keep track of the contact lenses extracted from the cabinet.   
     
     
         4 . A device according to  claim 3 , wherein the calculation module is incorporated in the remote computer server. 
     
     
         5 . A device according to  claim 1 , wherein the calculation module is housed in the cabinet. 
     
     
         6 . A device according to  claim 1 , wherein the means for identifying information relating to the content of a box containing the contact lens are arranged inside the cabinet, advantageously at an outlet from the cabinet. 
     
     
         7 . A device according to  claim 1 , wherein the device includes display device for displaying said additional data relating to the contact lens, which data includes data to be supplied by a user concerning the shape of the lens, the nature of the material forming the lens, and the frequency with which the lens is to be worn. 
     
     
         8 . A device according to  claim 1 , wherein the device includes a communications device for communicating with a personal computer of the user, which computer stores the data from the auto refractometer. 
     
     
         9 . A device according to  claim 1 , wherein the cabinet has a plurality of drawers, each drawer being arranged to receive a plurality of series of contact lenses of a given model so that each series of contact lenses differs from another series of contact lenses by its ophthalmic correction power. 
     
     
         10 . A device according to  claim 1 , wherein the data processor means associated with the calculation module are also arranged to determine the characteristics of a new lens from the characteristics of a previously identified lens and from additional data measured by the user on a patient wearing said previously identified lens, the additional data comprising at least a measurement of over refraction, said data processor means associated with said calculation module also being arranged to identify the location of this new lens within the cabinet. 
     
     
         11 . A device according to  claim 10 , wherein when said previously identified lens is a spherical lens, the data processor means associated with the calculation module are arranged to determine the sphere, the cylinder, and the axis of the new lens on the basis of the characteristics of the previously identified lens and of a measurement of over refraction performed on the patient wearing said previously identified lens. 
     
     
         12 . A device according to  claim 10 , wherein when the previously identified lens is a toric lens, the data processor means associated with the calculation module are arranged to determine the sphere, the cylinder, and the axis of the new lens from the characteristics of the previously identified lens and from measurements of over refraction and of rotation performed by the user on the patient wearing said previously identified lens. 
     
     
         13 . A device according to  claim 10 , wherein when the previously identified lens is a progressive lens, the data processor means associated with the calculation module are arranged to determine the sphere and/or the addition of the new lens from the characteristics of the previously identified lens, in particular its addition, from the age of the patient, and from over refraction, duochrome, and near and far vision visual acuity measurements, and from a determination of the dominant or fellow eye of the patient performed by the user on the patient wearing the previously identified lens.
