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.
Keratoscope, Battery-Powered
Ophthalmic
The Battery-Powered Keratoscope is a portable ophthalmic instrument that projects a ring or disc pattern onto the corneal surface to assess its curvature and regularity, useful in detecting corneal irregularities such as keratoconus. It is classified as FDA Class 1, the lowest risk level, subject only to general controls without any premarket notification submission. The product code is HLR, regulated under 21 CFR 886.1350, within the Ophthalmic medical specialty. This device is exempt from Good Manufacturing Practice (GMP) requirements under 21 CFR Part 820.

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.
