Ophthalmoscopy method using contact lens - has optical fibre bundles with exit ends round lens circumference to illuminate fundus, observed via distant headband scope

摘要

The method for ophthalmoscopy comprises the steps of arranging a contact lens in contact with an eyeball to be observed in order to observe the eyeball by eliminating refraction of light by the surface of the cornea of the eyeball and illuminates the fundus of the eyeball by transmitting illuminating light through several optical fibre bundles. These have exit ends arranged along the circumference of the contact lens and entrance ends arranged opposite to a light source. A magnified erect image is observed by means of a head band scope comprising a binocular telescopic optical system arranged opposite to and distant from the contact lens.
