Castroviejo Colibri Caliper

Castroviejo Colibri Caliper is a specialized ophthalmic microsurgical measuring instrument used to obtain precise ocular measurements during corneal surgery, cataract surgery, refractive procedures, glaucoma surgery, keratoplasty, and anterior segment microsurgery . The instrument combines the precision of a Castroviejo-style spring caliper mechanism with fine Colibri-type measuring tips , allowing surgeons to perform highly accurate measurements in delicate ocular structures. Its design is particularly suited for microsurgical applications where exact dimensional control is critical. The spring-loaded mechanism enables smooth, controlled opening and closing of the measuring arms while maintaining measurement consistency and repeatability. The finely calibrated scale provides accurate readings for corneal diameters, scleral distances, graft sizing, incision planning, limbal measurements, and other surgical landmarks. The slender Colibri-style tips allow precise placement on delicate ocular tissues while minimizing obstruction of the surgical field. This fine-tip design enhances visibility and facilitates accurate measurements under operating microscope magnification. Castroviejo Colibri Calipers are commonly used during corneal transplantation, penetrating keratoplasty, lamellar keratoplasty, cataract surgery, refractive surgery, glaucoma procedures, anterior segment reconstruction, and ocular surface surgery. The lightweight and ergonomically balanced construction provides excellent tactile feedback and instrument control, allowing surgeons to obtain precise measurements with confidence and efficiency. Manufactured from premium surgical-grade stainless steel, the instrument offers exceptional durability, corrosion resistance, and long-term calibration stability. The smooth satin or polished finish facilitates cleaning, sterilization, and maintenance. Available in multiple measurement ranges, graduation formats, tip designs, and calibration configurations, Castroviejo Colibri Calipers can be selected according to surgeon preference and procedural requirements. Widely used in hospitals, ophthalmic surgery centers, corneal specialty clinics, refractive surgery centers, academic institutions, and ambulatory surgical facilities, the Castroviejo Colibri Caliper is a trusted instrument for precision ophthalmic measurement. Fully reusable and autoclavable, the instrument is designed to withstand repeated cleaning and sterilization cycles while maintaining measurement accuracy, spring tension integrity, and clinical reliability.
