Castroviejo Caliper

Description

Castroviejo Caliper

The Castroviejo caliper measures small distances on the eye with two fine points. Surgeons use it to set and mark a distance before they cut or place a suture. We offer a 15mm and a 20mm range on an 8cm frame.

How the caliper reads

Two arms open across a marked scale. You set the gap, then lock it with the screw. After that, the tips touch the eye to mark or check the distance. So you can repeat the same measure at more than one point.

15mm or 20mm range

Both ranges share the same 8cm length. Pick by the largest distance you need.

• 15mm: for most short measures near the limbus.
• 20mm: when you need a wider span.
• Both: if your team covers a mix of procedures.

Where it helps

Strabismus surgeons often use a caliper to set how far a muscle moves. It also helps mark incision length or a point a set distance from the limbus. In addition, it may help in other surgery that needs a precise mark.

Reading it with care

Read the scale straight on, not at an angle. Then check the gap once more before you mark. Also, keep the tips light on the tissue, because pressure can shift the mark.

Cleaning the scale and screw

Clean the screw and the scale after each use. A soft brush lifts dried fluid from the marks. Then dry it fully and check that the arms still move smoothly.

How to order a caliper

Calipers ship non-sterile, and each one is reusable once it has been through your cleaning and sterile cycle. Scale, screw and arms share three years against manufacturing defects. Caliper stainless meets ASTM F899. For muscle cuts after you measure, see the Castroviejo tenotomy scissors. Also browse the ophthalmic surgery category and the common queries page.
