Redesigned with a familiar form and feel, this direct ophthalmoscope boasts a 20X larger viewing area. When compared to the view through a standard 3.5 V ophthalmoscope, these are views you have to see.  Welch Allyn has listened to countless providers and have added Quick Eye alignment technology, to help direct patient gaze for better optic disc alignment. Paired with long-lasting LED lamps, and DuraShock technology, upgrade from your standard or pocket ophthalmoscope to enhance your eye exams. The PanOptic Plus ophthalmoscope is compatible with our 3.5 V power sources or pair with the Lithium Ion Plus power handle for increased efficiency.
