This invention relates to intraocular lenses. More particularly, this invention relates to intraocular lenses that have the ability to alter the light refractive power in response to changes in the tension of the ciliary muscle or ciliary body of the eye or any other accommodative forces. Lenses of this invention are generally referred to as interfacial, i.e., lens properties being defined as the interface of two liquids having different refractive indices, refractive accommodating lenses (IRAL).

Interfacial refraction accommodating lens (IRAL)

To determine the thread supply on a lower-thread bobbin (), holes () are arranged in the shape of a spiral in a flange () of the bobbin. Light from a light source (), which is directed towards the flange (), is reflected only by those holes (), behind which there is no longer any thread, so that the light beams () reach the rear flange () and can be reflected therefrom and received by the light receiver ().
