Photostimulator, Ac-Powered
Ophthalmic
The AC-Powered Photostimulator is an electrically powered device used in ophthalmic electrophysiology to deliver precisely controlled flashes of light to the retina, eliciting visual evoked potentials or electroretinographic responses for assessment of retinal and visual pathway function. It is classified as FDA Class 2, indicating moderate risk, and requires 510(k) premarket clearance before marketing in the United States. The product code is HLX, regulated under 21 CFR 886.1630, within the Ophthalmic medical specialty. This device is eligible for third-party 510(k) review by an FDA-accredited reviewer.
510(k) Clearances

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.
