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 K20-2062 features an ultra-sharp, micro-honed 9.00 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.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"5\"\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e\u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\"\u003eManufacturer:\u003c\/b\u003e Corza Ophthalmology (Manufactured by Katena Products Inc. \/ Barron Precision Instruments)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eProduct Brand Family:\u003c\/b\u003e Barron® Radial Vacuum Trephine Series\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eProduct Catalog Code (MPN):\u003c\/b\u003e K20-2062 (Cross-indexed in ophthalmic supply networks as K202062)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\"\u003eClinical Function:\u003c\/b\u003e Cutting\/Excision of the recipient corneal bed (Host tissue trephination)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,4,0\"\u003e\u003cb data-path-to-node=\"6,4,0\" data-index-in-node=\"0\"\u003eTrephine Blade Cutting Diameter:\u003c\/b\u003e 9.00 mm fixed sizing gauge (Perfect circular monobloc architecture)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,5,0\"\u003e\u003cb data-path-to-node=\"6,5,0\" data-index-in-node=\"0\"\u003eVacuum Chamber Architecture:\u003c\/b\u003e Segmented 360° ring divided into 16 isolated radial compartments\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,6,0\"\u003e\u003cb data-path-to-node=\"6,6,0\" data-index-in-node=\"0\"\u003eBlade Engineering Matrix:\u003c\/b\u003e Multi-stage honed solid stainless steel bar stock with integrated proximity cross-hairs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,7,0\"\u003e\u003cb data-path-to-node=\"6,7,0\" data-index-in-node=\"0\"\u003eSuction Source Mechanism:\u003c\/b\u003e Self-contained, hand-operated manual aspiration syringe system (Requires no external utility lines)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,8,0\"\u003e\u003cb data-path-to-node=\"6,8,0\" data-index-in-node=\"0\"\u003eSterility Presentation:\u003c\/b\u003e Arrives individually protected in a transparent plastic tray with a hermetically sealed Tyvek lid, ETO gas sterilized, and ready for immediate deployment\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,9,0\"\u003e\u003cb data-path-to-node=\"6,9,0\" data-index-in-node=\"0\"\u003eOperational Reusability Rating:\u003c\/b\u003e Strictly Single-Use Disposable (Discard immediately following the procedure; do not re-sterilize)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,10,0\"\u003e\u003cb data-path-to-node=\"6,10,0\" data-index-in-node=\"0\"\u003eKit Included Accessories:\u003c\/b\u003e 1 Pre-assembled 9.00 mm Radial Vacuum Trephine, 1 Suction Syringe with Tubing, and 1 Sterile Gentian Violet Tissue Marking Pen\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Katena","offers":[{"title":"Default Title","offer_id":48606366761185,"sku":null,"price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/0527\/8543\/files\/K20-2062.png?v=1782854954","url":"https:\/\/primismedical.com\/products\/katena-corza-barron-k20-2062-radial-vacuum-trephine-9-00mm-recipient-bed","provider":"Primis Medical","version":"1.0","type":"link"}
