Testing device for intraocular lenses has fluid-filled space receiving intraocular lens provided with test object and associated light source and further lens positioned for acting as artificial eye

摘要

The testing device has a fluid-filled space containing a reception device for an intraocular lens (IOL) to be tested, a transparent test object, e.g. a plate (P), with an associated light source (L), supported for measured displacement along the optical axis of the intraocular lens and a further lens (C) on the opposite side of the intraocular lens to the test object, with a detector (D) on the outside of the fluid-filled space for receiving an image of the test object provided by the intraocular lens and the further lens. The spacing between the test object and the intraocular lens corresponds to the spacing between the center of the eye and the intraocular lens and the spacing between the intraocular lens and the outer surface of the further lens corresponds to the spacing between the intraocular lens and the outer surface of the cornea.
