Gullstrand, Allvar (1862–1930)
Swedish opthalmologist. He received the 1911 Nobel Prize in Physiology or
Medicine for his contributions to dioptrics, the study of the refraction
of light by the eye. He invented many important
opthalmological tools, including the slit lamp, which aided the study of
the structure and function of the cornea,
and improved corrective lenses for use after surgery.
