The device is described as a "manually operated device for delivery of small amounts of viscoelastic fluid... during ophthalmic surgery." It dispenses fluid "much like a syringe." There is no mention of measurement, analysis, or diagnosis of a medical condition.
No
The device description clearly outlines a physical, manually operated instrument with components like a cannula, injection tube, internal reservoir, plunger tube, and finger wheels, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Sight Sciences Viscoelastic Injector is a surgical instrument used to deliver viscoelastic fluid into the eye during ophthalmic surgery. It is used in vivo (within a living organism), not in vitro (in a test tube or lab setting).
- Intended Use: The intended use clearly states it's for "delivery of small amounts of viscoelastic fluid... during ophthalmic surgery." This is a surgical procedure, not a diagnostic test performed on a sample.
The device is a surgical tool, not a diagnostic test.

Device Description
The Sight Sciences Viscoelastic Injector is a sterile, single use, manually operated instrument used by ophthalmologists to deliver small amounts of viscoelastic into the eye during ophthalmic surgery. The Viscoelastic Injector is designed to function with commonly used viscoelastic fluids made commercially available by companies such as Abbott Medical Optics (AMO), Bausch & Lomb, and Alcon. The Sight Sciences Viscoelastic Injector dispenses fluid on the principle of exchanging volumes much like a syringe. The handheld instrument includes a cannula, injection tube, internal reservoir, plunger tube and finger wheels. The finger wheels on the handle of the device are used to advance the plunger tube into the viscoelastic fluid reservoir thereby dispensing viscoelastic fluid. The finger wheels are placed on both sides of the handle facilitating viscoelastic delivery in either the left or right eye (OD or OS) using either hand.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing was designed and conducted to evaluate device integrity, delivery of viscoelastic solutions, simulated use testing, and dimensional and visual inspections. Acceptance criteria was based on viscoinjector dispensing performances, intrinsic strength of the materials, and the load to which the Sight Science Viscoelastic Injector would be subjected during intended use. Testing demonstrated that the proposed device performs as intended and is functionally equivalent to the predicate device.

Identification. An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.(b)

4.1 DEVICE DESCRIPTION
The Sight Sciences Viscoelastic Injector is a sterile, single use, manually operated instrument used by ophthalmologists to deliver small amounts of viscoelastic into the eye during ophthalmic surgery. The Viscoelastic Injector is designed to function with commonly used viscoelastic fluids made commercially available by companies such as Abbott Medical Optics (AMO), Bausch & Lomb, and Alcon. The Sight Sciences Viscoelastic Injector dispenses fluid on the principle of exchanging volumes much like a syringe. The handheld instrument includes a cannula, injection tube, internal reservoir, plunger tube and finger wheels. The finger wheels on the handle of the device are used to advance the plunger tube into the viscoelastic fluid reservoir thereby dispensing viscoelastic fluid. The finger wheels are placed on both sides of the handle facilitating viscoelastic delivery in either the left or right eye (OD or OS) using either hand.

The Sight Sciences Viscoelastic Injector dispenses fluid on the principle of exchanging volumes much like a syringe. The Viscoelastic Injector components responsible for the fluid dispensing are the following:
- Prior to use, the viscoelastic fluid is loaded into the reservoir (polycarbonate) . contained within the handle.
- The reservoir communicates with the plunger tube (stainless steel) which is . connected to the injection tube (polyimide). During use, the plunger tube displaces volume in the reservoir thereby dispensing fluid.
- . The injection tube is initially located within the cannula (stainless steel), advances and retracts from the device to dispense fluid. The injection tube is analogous to a syringe dispensing-tip.
- . The finger wheels move the injection tube in and out of the cannula tip and drive the plunger tube into the reservoir to dispense viscoelastic fluid in a controlled manner.
4.2 INDICATION FOR USE
The Sight Sciences Viscoclastic Injector is a manually operated device for delivery of small amounts of viscoelastic fluid, for example Healon™ or HealonGV™ from Abbott Medical Optics (AMO), Amvisc™ from Bausch & Lomb, or PROVISC™ from Alcon, during ophthalmic surgery.
4.3 TECHNOLOGICAL CHARACTERISTICS COMPARISON
The intended use and technical features of the Sight Sciences Viscoelastic Injector are substantially equivalent to the Viscolnjector (K050716) marketed by iScience Surgical. Both devices are manually operated for controlled delivery of small amounts of viscoelastic fluid. Fluid is dispensed from each system on the principle of exchanging volumes much like a syringe. Table 1 compares the attributes of the iScience Viscolnjector with the Sight Sciences Viscoelastic Injector.

Dear Dr. Gordon:
We have reviewed vour 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 gencral 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: Registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
