De Wecker and Masselon’s  1886-model Keratoscope. A keratoscope is used to evaluate  the shape of the anterior portion of the cornea for astigmatism. In 1880 Masselon and De Wecker introduced the first model of their keratoscope, which allowed the “qualitative evaluation [of the cornea] and shows severe corneal astigmatism by distortion of the catotropic images.” (von Haugwitz in Hirschberg, 1986:49). In 1886 they introduced another keratoscope  (the model on offer) “which made it possible to measure also the degree of heterotopia and the pupillary diameter. “(ibid.). The example we are offering was made by  Crêtes   and is complete,cased and in excellent condition. The handle is ebony.
