The value of clinical specular microscopy of the corneal endothelium has been limited by the extremely small field of view of the image obtained. This is largely a result of an overlying brilliant reflection from the objective (or air)/cornea interface. A modification to the applanating objective cone of the contract specular microscope is described, which virtually eliminates this reflection and gives a visible field of almost 1 mm2 of the endothelium. The theory behind the objective modification is presented, and other advantages of the system, such as reduction of eye movement, are noted.
