The description details a manually operated mechanical device for fluid delivery, with no mention of computational processing, algorithms, or learning capabilities.
No
The device is used to deliver viscoelastic fluid during ophthalmic surgery, not to treat a disease or condition itself. It is an instrument for fluid delivery.
No
Explanation: The device is described as a "manually operated device for delivery of small amounts of viscoelastic fluid... during ophthalmic surgery." It is for "dispens[ing] fluid" and is an "instrument used by ophthalmologists to deliver small amounts of viscoelastic into the eye". This indicates it is for therapeutic delivery, not for diagnosis.
No
The device description clearly describes a physical, manually operated instrument with components like a cannula, injection tube, 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:
- Intended Use: The intended use is to deliver viscoelastic fluid during ophthalmic surgery. This is a surgical procedure performed on the patient, not a test performed on a sample taken from the patient.
- Device Description: The device is described as a manually operated instrument for dispensing fluid into the eye. This aligns with a surgical tool, not a diagnostic test.
- Lack of Diagnostic Function: There is no mention of the device being used to analyze a sample, detect a condition, or provide diagnostic information. Its sole purpose is the delivery of a substance during surgery.
IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not perform any such function.

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 (00 or OS) using either hand.

§ 880.5725 Infusion pump.
(a)
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)

SUBSTANTIAL EQUIVALENCE:
The modified Sight Sciences Viscoelastic Injector is substantially equivalent to the original Sight Sciences Viscoelastic Injector cleared under K132494. Minor design modifications that improve device manufacturability were made to the reservoir system, priming nozzle, and injection tube. The modified Viscoelastic Injector has the same intended use and basic scientific technology as the original model.

DESCRIPTION OF THE DEVICE:
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 (00 or OS) using either hand.
Image /page/4/Figure/3 description: The image shows a diagram of The Sight Sciences Viscoelastic Injector. The diagram labels the different parts of the injector, including the cannula, finger wheels, reservoir and plunger tube, locking mechanism, injection tube, and viscoelastic fluid. The viscoelastic fluid is located inside the injection tube. The reservoir and plunger tube are located inside the handle shell.

INDICATIONS FOR USE:
The Sight Sciences Viscoelastic Injector is a manually operated device for delivery of small amounts of viscoelastic fluid, for example HealonGV or HealonGVTM from Abbott Medical Optics (AMO), Amvisc™ from Bausch & Lomb, or PROVISCTM from Alcon, during ophthalmic surgery.
TECHNICAL CHARACTERISTICS:
The Sight Sciences Viscoelastic Injector consists of the following components and accessories:
-
Cannula
-
Injection tube
-
Internal reservoir
-
Plunger tube
-
Finger wheels
The Viscoelastic Injector dispenses fluid on the principle of exchanging volumes much like a syringe. The components responsible for the fluid dispensing are the following:
- · The reservoir within the handle is analogous to a syringe plunger. Prior to use, the viscoelastic fluid is loaded into the reservoir.
- · The plunger tube is connected to the injection tube and it communicates with the reservoir. During use the plunger tube acts like a graduated cylinder.
- · The injection tube, initially located within the cannula, advances and retracts from the device to dispense fluid. The injection tube is analogous to a syringe dispensing-tip.
- · The user interfaces with the device by using the finger wheels. This action is analogous to moving the dispensing tip to the desired location and depressing the plunger handle.
PERFORMANCE DATA:
The Viscoelastic Injector's descriptive characteristics are well-defined and adequate to ensure equivalence to the predicate device. Additionally, performance testing was conducted to evaluate device integrity and the delivery of viscoelastic solutions. Acceptance criteria was based on viscoelastic injector dispensing performance, intrinsic strength of the materials, and the load to which the Sight Science Viscoelastic Injector would be subjected during intended use.
6
Testing demonstrated that the proposed device performs as intended and is functionally equivalent to the predicate device.
CONCLUSION:
The Sight Sciences Viscoelastic Injector meets all product design requirements and applicable standards and embodies technological characteristics similar to the predicate device, the device has been shown to be substantially equivalent to the predicate device, and is safe and effective.
