Device utilizes an electrically driven (6-9 volt DC) oscillating blade housed in a head that guides the blade across the cornea. System includes suction ring, microkeratome head, and blade; features a single arcuate gear rack with temporal pivot pin and two interchangeable heads with fixed thickness plates. Operated by a physician via footswitch. Device creates a corneal disc of preselected thickness and diameter. Substantial equivalence claimed to Automatic Corneal Shaper (K913697). ## Clinical Evidence Bench testing only. The device was tested to applicable safety standards and demonstrated performance equivalent to the predicate Automatic Corneal Shaper (ACS) in the creation of corneal resections. ## Technological Characteristics Materials: Stainless steel. Energy source: 6-9 volt DC electric motor. Mechanism: Single arcuate gear rack with temporal pivot pin; two interchangeable heads with fixed thickness plates. Patient contact components: Suction ring, microkeratome head, blade. Sterilization: Ethylene Oxide (EO). ## Regulatory Identification A keratome is an AC-powered or battery-powered device intended to shave tissue from sections of the cornea for a lamellar (partial thickness) transplant. ## Predicate Devices - Automatic Corneal Shaper ([K913697](/device/K913697.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
