## Intended Use
The Sensor Medical Single Use Tonometer Prism is intended for use as a disposable applanating and optical doubling prism for Goldmann style applanation tonometers.
## Device Story
The device is a disposable, sterile optical prism used as a component in Goldmann-style applanation tonometers. It functions as an applanating and optical doubling prism to facilitate the measurement of intraocular pressure. The prism is intended for use by trained healthcare professionals in clinical settings. By providing a single-use, sterile interface, it replaces reusable glass prisms, thereby reducing the risk of cross-contamination between patients during routine eye examinations.
## Clinical Evidence
No clinical data or performance testing provided; substantial equivalence is based on identical intended use and technological characteristics to the predicate device.
## Technological Characteristics
Material: PMMA. Dimensions: 30.0 +/- 0.1mm length, 6.6 +/- 0.1mm corneal contact diameter. Weight: 1.8 +/- 0.1 g. Principle: Optical applanation and doubling. Sterilization: Provided sterile for single use. Connectivity: None (mechanical component).
## Regulatory Identification
A tonometer and accessories is a manual device intended to measure intraocular pressure by applying a known force on the globe of the eye and measuring the amount of indentation produced (Schiotz type) or to measure intraocular tension by applanation (applying a small flat disk to the cornea). Accessories for the device may include a tonometer calibrator or a tonograph recording system. The device is intended for use in the diagnosis of glaucoma.
## Predicate Devices
- Luneau Tonometer Separation Prisms ([K023838](/device/K023838.md))

Dear Ms. O'Connell:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
{1}------------------------------------------------
