1834‐1908 Dutch ophthalmologist. He studied medicine at the University of Utrecht, and in 1858 became an assistant at the Dutch Eye Hospital, where he engaged in ophthalmological research while practicing medicine. In 1862, he invented a method for testing visual acuity, which earned him fame, and in 1877 he became professor of ophthalmology at his alma mater. His achievements include surgery for entropion and ectropion, as well as the Snellen procedure for ptosis. [Matsuda Hiroshi] Source: Heibonsha World Encyclopedia, 2nd Edition Information |
