Swedish ophthalmologic research has a long tradition dating back to the slit lamp of Gullstrand of the early 20th century through later concepts such as the use of sodium hyaluronate in cataract surgery and latanoprost in glaucoma treatment. University departments of ophthalmology are present at the Karolinska Institute in Stockholm and at the universities of Uppsala, Lund (Lund and Malm?), Link?ping, Gothenburg and Ume?.
