The shell prothesis, originally meant to be placed over the atrophic eye, caused serious problems when used after enucleation, which became more common practice in the second half of the last century. In the nineties of the last century Snellen Sr. tried to solve these problems by designing a light prothesis that filled up the empty space. At the insistence of Snellen, the Müller brothers in Wiesbaden succeeded in 1892 to blow a hollow artificial eye which proved to be a real success.

In the middle of the last century the question of the origin of accommodation was still unsolved. At the suggestion of Donders, Cramer used in 1851 a microscope to demonstrate that accommodation has to be ascribed to an increase in the curvature of the lens. Donders himself had several instruments made for the same purpose. These are still present in the collection of the Royal Netherlands Ophthalmic Hospital.

The first useful table model ophthalmoscope was designed by Donders and the instrumentmaker Epkens. With the use of this instrument Donders' pupil Van Trigt made the first drawings of the normal and pathological fundus of the eye. His contribution was of great importance for the early diffusion of knowledge of the fundus of the eye.

During the second half of the 19th century Donders, Snellen and co-workers of the Utrecht Eye Clinic played an important role in the development of clinical tonometry. These indefatigable researchers designed and built a number of tonometers of which most have been saved and which are now on display in a permanent exhibition in the Royal Netherlands Ophthalmic Hospital at Utrecht.
