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.

The External Eyelid Weight is a small, adhesive weight, typically made of gold or another biocompatible material, applied externally to the upper eyelid to assist gravity-assisted closure of the eyelid in patients with lagophthalmos, the inability to fully close the eye, which can result from facial nerve palsy or other conditions causing incomplete blink. Classified as a Class 2 device under 21 CFR 886.5700 within the Ophthalmic specialty, it requires 510(k) premarket notification. It carries no implant or life-sustaining flags.

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.
