No se pudo cargar la disponibilidad de retiro
Mechanical endothelial punch for donor corneal button preparation from the endothelial side of the corneoscleral rim — the essential tool for DSAEK / DSEK / DMEK endothelial keratoplasty corneal transplant surgery. Universal design accepts any trephine 6-11 mm diameter, precentered mechanism auto-aligns trephine + teflon block for all trephine sizes, spring recoil auto-retracts trephine after cut. Two plungers per set. Autoclavable + EO gas sterilizable. CE certified. $349 direct — versus $1,500-$3,500 for Barron / Coronet / Moria endothelial punches.
Clinical applications
- DSAEK (Descemet's Stripping Automated Endothelial Keratoplasty) — donor endothelial button punching from corneoscleral rim
- DSEK (Descemet's Stripping Endothelial Keratoplasty) — manual DSEK donor prep
- DMEK (Descemet's Membrane Endothelial Keratoplasty) — donor Descemet's membrane preparation (with specialized DMEK protocol)
- DALK (Deep Anterior Lamellar Keratoplasty) — anterior tissue punching for donor
- Eye bank preparation — pre-cut donor tissue processing for surgical delivery
- PK (Penetrating Keratoplasty) — full-thickness corneal transplant donor button
Key features
- Universal trephine acceptance: any size from 6 mm (small pediatric) to 11 mm (adult), fits standard trephines from Barron / Katena / Moria / Coronet — no need to buy vendor-specific punch
- Precentered auto-alignment: trephine + teflon block auto-center for any trephine size, ensuring symmetric punch every time
- Spring recoil: after cut, trephine auto-retracts back through spring system — prevents corneal tissue trauma from operator delay
- Two plungers per set: primary + backup for continuous surgical workflow
- Autoclavable + EO gas: full sterilization compatibility per eye bank + surgical OR protocols
- CE certified: European conformity for medical device in donor tissue processing

FAQ
How does this compare to Barron / Coronet punches?
Feature parity on essentials — universal trephine sizing, precentered mechanism, spring recoil, autoclave-compatible. Barron + Coronet have slightly more premium finish + tighter Q6-8 μm cut tolerance. Price differential: $349 vs $1,500-$3,500. For eye banks + international corneal programs, SciMed delivers full clinical utility at 15-25% of premium OEM pricing.
Which trephines fit?
Universal design accepts any 6-11 mm trephine from Barron, Katena, Moria, Coronet, or generic manufacturers. Standard hollow trephines used in corneal surgery.
Can I use for DMEK?
Yes with DMEK-specific protocol modification (different trephine depth setting, thinner tissue). Consult your corneal transplant training program for DMEK-specific protocols.
Sterilization?
Autoclave at 134°C standard cycle OR EO gas per eye bank protocol. Full sterilization compatibility — no proprietary cleaning restrictions.
