K221320 is an FDA 510(k) clearance for the Scanning Laser Ophthalmoscope Mirante [SLO/OCT Model] with Image Filing Softw.... Classified as Tomography, Optical Coherence (product code OBO), Class II - Special Controls.

Submitted by Nidek Co., Ltd. (Gamagori, JP). The FDA issued a Cleared decision on March 30, 2023 after a review of 328 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Ophthalmic FDA review panel, regulated under 21 CFR 886.1570 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Ophthalmic review framework, consistent with the majority of Class II 510(k) submissions.
