K173980 is an FDA 510(k) clearance for the Specular Microscope CEM-530. Classified as Microscope, Specular (product code NQE), Class II - Special Controls.
Submitted by Nidek Co., Ltd. (Gamagori, JP). The FDA issued a Cleared decision on March 14, 2018 after a review of 75 days - a notably fast clearance cycle.
This device falls under the Ophthalmic FDA review panel, regulated under 21 CFR 886.1850 - the FDA ophthalmic device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.
Device pattern: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
