Abstract: An apparatus for use in the inspection of an ophthalmic lens comprises: a cubic transparent inspection cuvette, the cuvette comprising walls defining a cubic cuvette interior space and a rectangular cuvette top opening; a filling a placement funnel comprising a funnel top opening and a rectangular funnel bottom opening, and further comprising a seal; a cuvette holder; and a funnel holder. Cuvette holder may hold cuvette at a cuvette filling and placement orientation, Funnel holder may hold funnel at a funnel filling and placement orientation at which a funnel outlet axis coincides with longitudinal axis of cuvette interior space. Cuvette holder and funnel holder are movable relative to each other to a filling and placement connection position, in which a liquid-tight connection between funnel bottom opening and cuvette top opening is formed by means of the seal.

Abstract: An automated device for determining the peel force to peel a lidding foil off of a top surface of a primary packaging shell comprises: a shell holder for holding the primary packaging shell to the top surface of which the lidding foil is sealed; a foil lifter for lifting a non-sealed end portion of the lidding foil up from the planar top surface of the primary packaging shell held by the shell holder; a foil gripper for grasping the lifted non-sealed end portion of the lidding foil; a foil peeler for peeling the sealed lidding foil with the lifted non-sealed end portion grasped by the foil gripper off of the planar top surface of the primary packaging; and a force sensor for determining the force required to peel the lidding foil off of the top surface of the primary packaging shell.

Abstract: A method for determining the inversion state of a soft contact lens (1), comprising imaging a soft contact lens having a convex surface (2, 3) and a concave surface (3, 2), a lens center and a lens edge (5) surrounding said soft contact lens (1), the method comprising using an optical coherence tomography system to obtain at least one sectional image of at least a part of the contact lens (1) comprising the lens edge (5), determining a cross-sectional edge geometry of the contact lens (1) extending from the lens edge (5) towards the lens center of the contact lens in the sectional image, the cross-sectional edge geometry corresponding to the convex and concave surface boundaries of the contact lens (1) in the sectional image, selecting a parameter defining the cross-sectional edge geometry of the contact lens (1) imaged and comparing the parameter defining the cross-sectional edge geometry of the contact lens (1) with a predetermined parameter defining a cross-sectional edge geometry of a non-inverted contact

Abstract: Method for determining the refractive index (n) of a material of a contact lens, in particular of a soft contact lens, the contact lens (1) having a first surface and a second surface defining a lens geometry there between, by measuring the wavefront issued by the contact lens (1) with a wavefront sensor (4), obtaining data of the geometry of at least one section of the contact lens (1) with an optical coherence tomography system (3) and communicating the geometry of the at least one section of the contact lens (1) from the optical coherence tomography system (3) to an analyzer, particularly a computer, and determining the refractive index (n) of the material of the contact lens from the geometry of the at least one section of the contact lens and from the wavefront issued by the contact lens (1).
