The MST 7.00mm Disposable Trephine (Item #AB-67700) is a purpose-built ophthalmic instrument in the Trephines & Punches portfolio. Designed around its specific working geometry, it features 7.00mm diameter. Our sterile, single-use vacuum trephines consistently create accurate and uniform cuts by dividing the corneal chamber into 16 chambers, thus reducing corneal distortion. The ergonomic grip allows for easier control while making precision cuts on patient corneas. 16 radial marks allow for easy suture placement. Sold individually. This combination of thoughtful design details and clearly defined specifications helps surgeons quickly identify the configuration that best fits their preferred technique and procedural needs.
