Mikhail Mikhailowitsch Woinow

He served as an assistant to Hermann von Helmholtz (1821-1894) and Otto Becker (1828-1890) at the University of Heidelberg and to Carl Ferdinand von Arlt (1812-1887) in Vienna.

Later he established an ophthalmologic practice in Moscow, where he also gave lectures at the university.

[1] In Vienna he conducted pioneer ophthalmometric research with August Leopold von Reuss (1841-1924) that included studies of corneal astigmatism following cataract extraction.

The two men are credited as the first to describe exact ophthalmometric observations on "wound astigmatism".

[2][3] In addition to work in ophthalmometry, Woinow published a number of papers on subjects such as ametropia, the blind spot, binocular vision, color vision, accommodation, etc.
