Product Code: PUF FDA class 2

Ocular Peg, Exempt

Ophthalmic

View full classification →

The Ocular Peg (Exempt) is an ophthalmic implant used to restore motility to an ocular prosthesis by providing a stable coupling mechanism within the orbital implant, improving the cosmetic appearance and movement of an artificial eye following enucleation or evisceration. Product code PUF is the Class II exempt counterpart of MQU, exempted from the 510(k) requirement under the 21st Century Cures Act, subject to the limitations in 21 CFR 886.9. Under regulation 21 CFR 886.3320, it is a Class II device subject to general and special controls. It is flagged as an implant, reflecting its use as a permanently implanted component within the eye socket.

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.
