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.

Ophthalmic
The Fresnel Flexible Diagnostic Lens is a thin, flexible ophthalmic lens using Fresnel optic principles, used as an accessory in slit-lamp examinations or attached to existing spectacles for diagnostic evaluation of the posterior eye. It is classified as FDA Class 1, representing the lowest risk category, with no premarket notification required; compliance with general controls is sufficient. The product code is HJJ, regulated under 21 CFR 886.1390, within the Ophthalmic medical specialty. This device is exempt from Good Manufacturing Practice (GMP) requirements under 21 CFR Part 820.
No 510(k) clearances found for "HJJ". Try a different K-number, product code, or device name.
What is a Predicate 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.
