Abstract
Method of determining the position of a target drill hole to be drilled in a target corrective lens having an expected target outline after shaping, the position being determined from a reference lens having a reference outline and at least one reference drill hole, the method includes: acquiring an image and at least one characteristic of the curvature of the reference lens; determining, in the acquisition plane, the reference distance in projection between the projection of a reference anchor point of the associated reference lens and the reference lens and the projection of a reference drilling point of the reference drill hole calculating the three-dimensional reference distance between the reference anchor point and the reference drilling point as a function of the characteristic of the curvature of the reference lens () and of the determined reference distance; and determining the position of the target drilling point for the target drill hole of the target corrective lens as a function of the calculated three-dimensional reference distance (R; R).
