Castroviejo's precision profile extends to this continuous-measurement caliper, which spans 0 to 15mm in fine increments. The straight configuration and graduated markings support rapid intraoperative measurement of corneal grafts, graft bed dimensions, or anterior chamber anatomy during phacoemulsification or keratoplasty. Compact 76mm length fits all ophthalmic surgical hand.
Features & Benefits
The Castroviejo caliper is a precision measurement instrument engineered for ophthalmic surgical planning and assessment. This titanium tool measures distances from 0 to 20mm in 1mm increments with dual-sided scale readings for rapid reference. A thumb-screw adjustment provides reliable locking.
The Braunstein fixed caliper features double-ended fine points with 3mm and 3.5mm measurement ends, designed for precise anterior chamber depth, corneal thickness, and surgical landmark measurement during ophthalmic surgery. The fine-point geometry enables accurate positioning at critical landmarks like the limbus and scleral spur. This 83mm instrument supports reliable biometric assessment during cataract and refractive procedures.
The Stahl A/C caliper measures corneal diameter from white‑to‑white, supporting IOL sizing and limbal landmark planning. The scaled arms read the horizontal corneal dimension directly, allowing the surgeon to capture the measurement at the slit lamp or operating microscope without secondary tools.
The Braunstein fixed caliper bridges two measurement points (2mm and 2.5mm) on a single instrument, supporting rapid surgical assessment of corneal thickness, anterior chamber depth, or graft dimensions during refractive or corneal transplant cases. Double-ended design eliminates the need for tool switches between common measurements. Straight profile maintains precise alignment.
Braunstein fixed calipers offer fixed measurement points at 3.5mm and 4mm on opposite ends, supporting rapid marking of LRI lengths, capsulorhexis diameters, and corneal landmarks without dial adjustment. The fine points deposit ink or indent tissue precisely, and the 83mm body suits microscope work.
The Castroviejo angled caliper is a precision measurement instrument for direct corneal diameter and anterior segment anatomic assessment during surgical planning. Its 45‑degree curved shafts, polished finish, and fine grooved tips enable repeatable 0‑to‑20mm measurements in 1mm increments. The thumbscrew lock holds measured distances steady, while the compact 86mm length supports comfortable handheld positioning.
Reading 0 to 20mm in 1mm increments, this Castroviejo caliper measures corneal landmarks, limbal positions, and incision distances during anterior segment surgery. Dual‑sided scales let the surgeon read the value from either orientation, and the thumb‑screw mechanism captures the setting for repeat reference. The 38mm mid‑screw‑to‑tip working length suits microscope work.
This Castroviejo caliper measures anterior segment dimensions with 1mm precision across a 0‑40mm range. The adjusting screw mechanism locks measurement values, enabling accurate documentation of corneal diameter, limbal location, and surgical reference zones. The straight 178mm length supports stable positioning during pre- and intraoperative assessment.
This Castroviejo marking caliper serves the specialized role of measuring corneal diameter or astigmatic axis during cataract and refractive procedures. Curved shafts reduce hand fatigue and improve ergonomic reach, while groove detailing and dual-side scale readings (0‑20mm in 1mm increments) allow rapid documentation of surgical measurements without instrument repositioning.
Jameson calipers measure 0 to 80mm in 1mm increments and 0 to 3 inches in 1/16‑inch increments, sized for marking and verifying distances during strabismus, oculoplastic, and refractive surgery. Narrow flat 3mm tips reach reliably to the limbus or lid margin, and a thumbscrew locks the caliper at the measured setting. Dull finish suppresses reflection under microscope view.
The Osher internal caliper provides precise measurement of anterior chamber depth and crystalline lens vault in cataract and refractive planning. Its fine-pointed tips minimize contact trauma while measuring critical intraocular distances up to 10mm in 1mm increments. The 68mm length supports delicate insertion and measurement accuracy.
This Stahl anterior chamber caliper is designed for accurate white-to-white corneal diameter measurement. Its fine-point arms provide stable contact at the limbus, supporting reliable sizing for intraocular lens planning and clinical assessment.
The Stahl caliper at 40mm carries fixed measurement points from 7mm through 13mm in 0.5mm increments, sized for intraoperative measurement of corneal diameter, IOL haptic span, and pupil aperture during ophthalmic surgery. The dull finish reduces glare under microscope illumination, and the fixed‑point design eliminates reading variability.
The Thorpe caliper achieves extended measurement range through dual-scale design: up to 80mm in 1mm increments, plus finer readings to 3 inches in 1/16-inch steps. Thumbscrew locking secures a chosen measurement for documentation or reference during complex cases. Angulated 3mm-wide tips and dull finish minimize reflection and improve visibility in anterior segment surgery.
