Fixed Caliper for Consistent Aphakic and Phakic Measurements

The Thornstein fixed caliper 2 3/4" is a measurement instrument designed to help dental and ophthalmic professionals assess defined distances during procedural planning and instrument handling. Its fixed configuration provides two clearly identified measurement options: 2.0 mm for aphakic applications and 2.5 mm for phakic applications. This specification-based design supports a straightforward workflow when a consistent reference is needed, while the compact 2 3/4" length is practical for controlled handling around the operative field. Suitable for approved Dental and Ophthalmic applications, it keeps measurement selection clear without relying on adjustable settings.

Use Cases

Measure or reference a 2.0 mm dimension for aphakic applications.
Measure or reference a 2.5 mm dimension for phakic applications.
Support dental workflows requiring a fixed caliper reference during procedural preparation.
Support ophthalmic workflows requiring selection between the named aphakic and phakic measurements.
Use as a controlled, repeatable reference when an adjustable caliper is not required.

Specifications

Care & Reprocessing

Clean and reprocess the caliper according to facility protocols and the applicable instructions for use.
Inspect the fixed measuring ends and body for visible soil, damage, or distortion before and after use.
Handle the instrument carefully to preserve the defined measurement geometry.
Store in a clean, protected location where the caliper will not be bent, struck, or exposed to unnecessary contamination.
