Device, kit and methods for use in ophthalmology

摘要

The present invention refers to a device and a kit for the shipment and preservation of corneal lenticules ready for use in a lamellar keratoplasty surgery. The device (1) comprises a first open portion (2), apt to receive and contain the lenticule, and a fenestrated lid (10) to close said first portion. The device further comprises a second portion (3) of substantially tubular shape with a diameter lower than the diameter of the lenticule. The device may further comprise a third portion (7) apt to be reversibly connected to a grip means. The fenestrated lid and the front opening (5) allow preservation fluid to nourish the lenticule tissue during the preservation and/or the shipment. The present invention also refers to a method for preserving, shipping and prearranging the lenticules so as to facilitate posterior lamellar keratoplasty surgery (or endokeratoplasty).

主权项

1. A method of preparing and supplying, from an eye bank to an operating room, a corneal lenticule for use in lamellar keratoplasty surgery, comprising:
(a) preparing anterior and posterior lenticules, isolated and overlapped, from a cornea isolated at a structure dedicated thereto; (b) arranging the anterior and posterior lenticules inside a device comprising: a first open portion adapted to receive and contain said lenticules, a fenestrated lid adapted to close said first portion, and a second portion of a substantially tubular shape with a diameter smaller than said lenticules' diameter, and having a first open end and a second open end connected to said first portion via a connecting portion so as to form a single container body, wherein the device has a groove at said first open end; so as to have the stromal face of the anterior lenticule adhere to the internal wall of said device and the endothelial face of the posterior lenticule facing the lumen of the device, and closing the fenestrated lid which seals rearwards the device; (c) immersing said device containing said lenticules into a sealable container comprising a suitable preservation solution; and (d) transferring the container containing the device and the lenticules ready for use to the operating room.
