510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.
Media, Corneal Storage
Unknown
The Corneal Storage Media (product code LYX) is an ophthalmic solution used to preserve and store donor corneal tissue prior to transplantation, maintaining corneal viability and endothelial cell function during the storage period. It is currently unclassified (Class U) with no assigned regulation number or formal medical specialty, and is reviewed under the Ophthalmic (OP) panel. As an unclassified device, its regulatory pathway has not been fully determined. It is not flagged as an implant or life-sustaining device.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
