He returned to Denmark in 1910 as Professor of Ophthalmology and head of the Eye Department, Rigshospitalet. He published > 100 scientific papers, mainly on optical physiology (aetiology of myopia, entoptic phenomena, Purkinje pictures, the polygonal pattern provoked by corneal rubbing). He studied the law of Listing and invented the ophthalmophacometer, which measures the changes in the front and back curvatures of the crystalline lens during accommodation. Tscherning also studied aberration and calculated and constructed forward bulging periscopic (punctal) spectacle lenses.The Keystone Publishing Company published a journal called the 'The Keystone' which was the organ of the Jewelry and Optical Trades.
