Amsler, Marc (1891–1968),
Swiss ophthalmologist. Amsler was chief ophthalmologist at the University of Lausanne from 1935 to 1944. He served as professor of ophthalmology at the University of Zurich's eye clinic from 1944 to 1961. It was at this institution that he performed the first corneal transplantation in 1951. Amsler made major contributions to the understanding of uveitis, in addition to publishing works on keratoconus. He developed the Amsler grid after experimenting extensively with different patterns and colors for the grid's design.
