Castroviejo Calipers — Pattern and Clinical Use
Ophthalmic surgery depends on measurement: the distance of a muscle insertion from the limbus in strabismus surgery, graft diameter in keratoplasty, incision length and IOL positioning. The caliper’s fine points are set against the graduated scale and placed on the tissue, giving a direct millimetre reading. Because surgical decisions follow the reading, scale accuracy is the entire value of the instrument.
Calipers are supplied straight or angled, with the angled pattern letting the surgeon read the scale without obstructing the field. Locking screws hold a set measurement for repeated transfer.

Material, Finish and Quality Control
We forge Castroviejo Calipers from 316L austenitic stainless. The graduated scale is verified against a calibrated reference, since surgical decisions are taken directly from the reading. Each batch passes Rockwell hardness testing, dimensional checks on scale accuracy against calibrated reference, and visual inspection under our ISO 13485 system before passivation and final finishing. Mirror and satin finishes are both available — satin is usually specified where glare under operating lights is a concern.
Who Sources Castroviejo Calipers From Surgical Star
Castroviejo calipers sell to ophthalmic surgeons and eye hospitals, and are standard in strabismus, corneal and refractive surgery sets.
OEM, Certification and Ordering
Every Castroviejo Calipers can be produced as a private-label line: your logo laser-marked on the arm, your catalog numbers, and your own printed packaging, manufactured from your drawings or a reference sample. Manufactured under an ISO 13485 quality system, CE-marked to EU MDR 2017/745 and covered by US FDA establishment registration. A certificate of conformity and an ASTM F899 material certificate for the exact steel grade ship with your order.
MOQs are low and new-brand friendly, and vary with pattern, finish and branding. Pricing is direct from the factory and tiered by volume. After you approve a branded pre-production sample, bulk production typically runs four to six weeks and ships worldwide DDP with HS codes handled. See how OEM & private label works →

Frequently Asked Questions
What are ophthalmic calipers used for?
Measuring distances on the eye — muscle insertion from the limbus, graft diameter, incision length and IOL positioning.
Straight or angled?
Angled patterns let the surgeon read the scale without obstructing the surgical field, which many prefer. Straight patterns read directly.
How is scale accuracy assured?
Each caliper is verified against a calibrated reference, because surgical decisions are taken directly from the reading.
Can you manufacture these under our own brand?
Yes — full OEM and private label. We laser-mark your logo and catalog numbers, pack in your branded boxes, and work from your drawings, tech pack or a reference sample, with a pre-production sample approved before any bulk run.
