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.
Laser, Neodymium:Yag, Ophthalmic For Posterior Capsulotomy And Cutting Pupilla
Ophthalmic
The Neodymium:YAG Laser for Posterior Capsulotomy and Cutting Pupillary Membranes (product code LXS) is an ophthalmic laser system that uses Nd:YAG laser energy to perform non-contact photodisruption of the posterior lens capsule following cataract surgery or to cut pupillary membranes obstructing vision. Regulated under 21 CFR 886.4392 and classified as a Class 2 device, it requires a 510(k) premarket notification and is eligible for third-party review. The device falls under the Ophthalmic specialty. It is not an implant and is not life-sustaining.

6 matchesWhat 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.
