American Optical Keratometer

This used American Optical Keratometer is a manual ophthalmometer designed for measuring the curvature and refractive power of the cornea. It supports the essential work of contact lens fitting, astigmatism diagnosis, and general anterior segment evaluation, giving practitioners the diopter and radius data needed to select or verify lens parameters with confidence. Built with the solid mechanical styling characteristic of American Optical instruments, this keratometer features the traditional mires target and doubling prism arrangement, mounted on a stable base with fine focus and alignment controls. Its dependable optics and straightforward operation made it a common fixture in optometric practices, university teaching clinics, and vision research settings where manual measurement precision was valued over automation. Offered here in used condition, this instrument continues to function as intended and is ready for integration into an active exam room. It provides a budget conscious way for a practice to maintain manual keratometry capability, whether as the primary corneal measurement tool or as a reliable secondary unit supporting newer automated equipment.
