Barron® Radial Vacuum Recipient Corneal Trephine System | Model K20-2059 | 8.25 mm Diameter Blade Profile | Integrated 16-Compartment Suction Chamber Matrix | Sterile Single-Use Recipient Bed Surgical Incision Element

Expiration: 2028-11-01

The Katena Corza Barron K20-2059 is a professional-grade, sterile, single-use ophthalmic surgical instrument expertly engineered to perform a highly precise, perfectly circular, and perpendicular incision on a patient's diseased recipient cornea during penetrating keratoplasty (PK) procedures. Recognized as a global clinical standard in anterior segment surgery, this second-generation mechanical trephine incorporates a 360-degree vacuum stabilization ring divided into 16 individual compartments. When connected to the included hand-operated syringe module, this radial suction matrix firmly secures the instrument to the recipient eye while reducing focal tissue aspiration, which preserves the natural contour of the cornea and prevents structural deformation during cutting. The K20-2059 features an ultra-sharp, micro-honed 8.25 mm trephine blade precision-machined from a solid rod of stainless steel rather than bent razor-strip stock, ensuring a flawless circular profile free of edge distortions. Built with an internal cross-hair alignment grid for precise positioning over the pupil center, the vacuum chamber's radial spokes also leave subtle, evenly spaced epithelial indentations. These indentations can be highlighted with the accompanying sterile gentian violet ink pen to guide symmetrical suture placement, drastically reducing post-operative astigmatism.
