K990227 is an FDA 510(k) clearance for the ULTRASHAPER KERATOME. Classified as Keratome, Ac-powered (product code HNO), Class I - General Controls.

Submitted by Lasersight Technologies, Inc. (Winter Park, US). The FDA issued a Cleared decision on January 31, 2000 after a review of 371 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Ophthalmic FDA review panel, regulated under 21 CFR 886.4370 - 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.
