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.
Excimer Laser System
Unknown
The Excimer Laser System (product code LZS) is an ophthalmic surgical device that uses ultraviolet excimer laser energy (typically at 193nm) to reshape the cornea through photoablation, correcting refractive errors such as myopia, hyperopia, and astigmatism in procedures such as LASIK and PRK. It is classified as a Class 3 device requiring Premarket Approval (PMA) due to the irreversible nature of corneal tissue removal and associated surgical risks. The device has no formal regulation number or medical specialty designation and is reviewed under the Ophthalmic (OP) panel. It is not an implant and is not life-sustaining.

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.
