It functions as a mechanical cutting instrument during ophthalmic surgery. The device is intended for use by trained ophthalmic surgeons in a clinical or surgical setting. It is supplied sterile via gamma radiation. The blade is physically and functionally equivalent to the predicate Moria M2 blade, ensuring compatibility with the existing microkeratome system. Its use allows for corneal resections with accuracy and variability comparable to the predicate device, facilitating standard microkeratome-assisted procedures. ## Clinical Evidence Bench testing only. Non-clinical testing on porcine eyes demonstrated that corneal resections performed with the subject blade had similar accuracy and variability to the predicate device. Physical measurements, sharpness, and fit were also confirmed to be comparable to the predicate. ## Technological Characteristics Material: 400 series stainless steel. Form factor: Replacement blade for Moria M2 microkeratome. Sterilization: Gamma radiation to SAL 10^-6 per EN 552. Single-use, disposable. ## 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 - Moria M2 Microkeratome blade ([K002191](/device/K002191.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
