ABSTRACT:
A wet cornea microscope enables a viewer to see a substantially magnified image of a sample. The microscope includes a barrel having a hollow tubular interior and first and second ends. An objective lens is coupled to the first end of the barrel and is positionable in close proximity to the sample. An eyepiece forms a fluid-filled chamber and includes an optically transparent window which is positionable in alignment with the second end of the barrel. The cornea of one of the viewer's eyes is completely immersed in the fluid within the fluid-filled chamber. The contact of the fluid with the cornea of the viewer's eye effectively eliminates the refractive effect of the cornea/aqueous humor interface of the viewer's eye and permits the microscope to form a substantially magnified image of the sample on the retina of the viewer's eye.
