Ophthalmic surgery fluid retention ring

An ophthalmic surgery fluid retention ring is a sterile, single-use device designed to be placed on the cornea during eye surgery to maintain fluid within the eye by forming a physical barrier. It functions as a bevelled, hollow cylinder with a double-walled vacuum seal that creates an airtight interface with the corneal surface, helping to stabilize intraocular conditions during procedures such as cataract or corneal surgery.

Devices in this category are supplied as sterile, single-use instruments and are regulated based on their intended use and design as ophthalmic surgical tools. They are typically classified as medical devices requiring compliance with sterility and biocompatibility standards, and are not intended for reuse or reprocessing after a single surgical procedure.
