Digital Wide-field Imaging System

The 3nethra neo is a compact, portable, and easy-to-use mydriatic wide-field digital imaging system used for the photo documentation of ocular diseases that manifest in human eyes. The ergonomically designed, lightweight hand piece allows for single-handed operation, and captures 120-degree high-resolution images of the posterior and anterior segments of the eye. The device acquires only digital photographs of the eye and does not provide any analysis or diagnosis. The contact device is easily operated by qualified clinicians and can be deployed in versatile clinical environment such as hospitals, operating rooms, and Neonatal Intensive Care Units (NICU).
