Thornstein fixed caliper 2 3/4 aphakic: 3.0mm, phakic: 3.5mm

Clear, Consistent Measurement for Dental and Ophthalmic Workflows

The Thornstein fixed caliper is a precision measuring instrument designed for comparing and assessing defined dimensions during dental and ophthalmic procedures. Its fixed 2 3/4" format supports controlled handling, while the clearly identified aphakic 3.0 mm and phakic 3.5 mm measurements help users select the appropriate reference point for the task at hand. By placing both measurement options within one compact instrument, it can support efficient intraoperative or procedural workflows where repeatable sizing and straightforward access are important. The fixed design also provides a simple, focused alternative to adjustable measurement tools when these established dimensions meet the clinical requirement.

Use Cases

• Use the fixed caliper to assess or compare 3.0 mm aphakic measurements in ophthalmic workflows.
• Use the 3.5 mm phakic measurement as a reference during applicable ophthalmic procedures.
• Support dental measurement tasks requiring a compact caliper with defined fixed dimensions.
• Select the appropriate caliper reference according to whether the task calls for the aphakic or phakic measurement.
• Incorporate the 2 3/4" instrument into organized dental or ophthalmic setups where direct, repeatable measurement is required.
