Which tool is an attachment designed to enhance the accuracy of a keratometer?

• A. Pachymeter
• B. Topogometer
• C. Radiuscope
• D. Myoflange device

Answer: (B)

A topogometer is an attachment designed to enhance the accuracy of a keratometer by providing detailed mapping of the curvature of the cornea. While a keratometer is useful for measuring the curvature of the central portion of the cornea, a topogometer offers a more comprehensive analysis by measuring the entire surface. It captures elevation data across the corneal surface, allowing for a more nuanced understanding of its shape and any irregularities present. This additional information can significantly improve the precision of diagnoses and treatment plans in conditions like astigmatism or keratoconus. In contrast, other tools like a pachymeter measure corneal thickness, which is important but serves a different purpose. A radiuscope is primarily used for measuring the radii of lenses rather than the corneal surface itself. The myoflange device is also unrelated, as it does not assist in measuring corneal curvature but could relate to other ocular measurements or adjustments in fitting lenses.
