HATE Castroviejo Caliper – 0–20 mm Measuring Caliper

The HATE Castroviejo caliper is a German-made ophthalmic caliper with two fine, pointed tips, a curved scale arc and a knurled adjusting screw. It measures and marks small distances on the skin, eyelid, and cartilage with great accuracy.

What Is a Castroviejo Caliper?

The Castroviejo caliper was designed by the ophthalmologist Ramón Castroviejo for measuring small distances in eye surgery. The two tips work like a compass: the adjusting screw opens them to the required distance, and the reading is shown on the curved scale. The fine points can then be pressed lightly on the skin to mark the measured distance.

In plastic surgery the Castroviejo caliper is used to plan eyelid incisions, mark graft sizes, and check symmetry. Standard models measure about 0–20 mm in 1 mm steps.

Clinical Uses of the Castroviejo Caliper

Why Use an Ophthalmic Caliper in Plastic Surgery?

Small measurements matter most in the face: a difference of 1 mm in eyelid skin removal or graft size is visible. An ophthalmic caliper gives exact, repeatable measurements and can mark them directly on the skin. Being made of stainless steel, it can be sterilized and used in the surgical field throughout the procedure.

How to Use the Castroviejo Caliper

1. Turn the adjusting screw to open the tips to the required distance, reading the scale.
2. Place the tips on the points to be measured, or press lightly to mark the skin.
3. Transfer the measurement to the other side to check symmetry.
4. Close the caliper after use to protect the tips.
