The SIS, Ltd., ACCM microkeratome is a precision-manufactured instrument indicated for lamellar resection of the cornea.
The SIS, Ltd ACCM Microkeratome is a precision-manufactured instrument designed for cutting a precise corneal disc of preselected thickness and diameter. The design, material and operating principle are very similar to those of the predicate devices.
The provided text does not contain detailed acceptance criteria, specific performance metrics, or a study design for a device. It primarily focuses on the submission of a 510(k) for a microkeratome and its substantial equivalence to predicate devices. Therefore, I cannot populate the table or answer the questions related to acceptance criteria and study details.
Here's a breakdown of what the document does include:
- Device Name: Surgical Instrument Services (SIS), Ltd. Advanced Computer Controlled Microkeratome (ACCM)
- Intended Use: Lamellar resection of the cornea.
- Predicate Devices:
- Technological Comparison (Table 1): This table outlines various technical characteristics of the SIS-ACCM and its predicate devices, demonstrating similarity in operating principle, intended use, blade material, and general features. This comparison is used to establish substantial equivalence.
- Nonclinical Tests: The summary states that "The ACCM microkeratome has been designed and tested to applicable safety standards. Parameters related to lamellar resection were validated through extensive preclinical testing. The ACCM microkeratome does not raise any new issues of safety, effectiveness, or performance of the product." However, specific details of these tests, their results, or acceptance criteria are not provided.
- FDA Clearance: The document includes the FDA's letter granting 510(k) clearance based on substantial equivalence, permitting the device to be marketed.
Therefore, the requested information regarding acceptance criteria and a study proving the device meets those criteria cannot be extracted from this document. The document's purpose is to demonstrate substantial equivalence, not to present a detailed performance validation study with specific acceptance criteria and results.

Re: K993190 Trade Name: Advanced Computer Controlled Microkeratome (ACCM) Regulatory Class: I Product Code: 86 HNO Regulation: 886.4370 (Keratome) Dated: January 13, 2000 Received: January 14, 2000
Dear Ms. Gordon:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations .
