K221601 is an FDA 510(k) clearance for the MS-39. Classified as Tomography, Optical Coherence (product code OBO), Class II - Special Controls.

Submitted by C.S.O. S.R.L. (Scandicci, IT). The FDA issued a Cleared decision on September 1, 2023 after a review of 456 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: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Ophthalmic submissions.

What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Ophthalmic devices follow this clearance model.
