Regulatory Classification

Identification

An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Special Controls

*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

#### III. PREDICATE DEVICE

Substantial equivalence to the following predicate device is as follows:

### IV. DEVICE DESCRIPTION

The LIGHTMED Ultrasound System is a portable ultrasound biometric ruler intended for use in ophthalmic applications. The system allows for the measurement of several key ocular features including axial length (AXL), anterior chamber depth. The device is used by coupling the probe / transducer to the eye either through direct contact or immersion methods. Available modes are biometric B-scan and UBM.

{4}------------------------------------------------

The B-Scan mode produces a live, two-dimensional image to facilitate the identification and measurement of ocular pathologies in the posterior-chamber of the eye, particularly when view of the chamber is obscured, such as is the case with cataracts.

The UBM mode can be used with a 35 MHz or a 50 MHz transducer. Because of the higher frequency of the transducer, it is expected that its greatest field of application will be in visualizing the anterior segment, because the focus area is about 11 mm from the transducer plane. The system will visualize other parts of the eye, but the resolution is not as high.

LIGHTMED Ultrasound System is a stand-alone system that runs on a Windows 10 platform and may be networked (by the user) for interface with electronic medical records systems, printing, and other purposes. The system consists of the LIGHTSonic B|UBM console, ultrasound probe(s) and transducer, and foot pedal.

## V. INDICATIONS FOR USE

The LIGHTMED Ultrasound System is a non-invasion diagnostic ophthalmic ultrasound instrument specifically designed for measurements inside the ocular structures including orbital, anterior and posterior segment of eye.
