Bausch & Lomb 71-21-36 Keratometer

This Bausch & Lomb 71-21-36 is a used manual keratometer that has long been a trusted instrument for measuring corneal curvature in optometric and ophthalmic settings. As a classic Bausch & Lomb design, it relies on precise mire alignment and manual reading to determine the radius and axis of corneal curvature, a technique that continues to be taught and used in clinics worldwide. Its durable mechanical construction has made this model a staple on many exam room counters for decades. Clinically, this keratometer is used for fitting contact lenses, assessing astigmatism, and providing baseline corneal measurements before refractive or cataract surgery. Its manual operation gives experienced practitioners fine control over alignment and reading accuracy, which many clinicians still prefer for routine keratometry work. The instrument is well suited for optometry schools, smaller practices, and any setting where a dependable manual keratometer is needed as a primary or backup device. Being sold in used condition, this 71-21-36 unit has been inspected for smooth mechanical operation and clear optics. It offers a cost effective way for a practice or training program to acquire a proven manual keratometer without the expense of newer automated alternatives.
