Superior high quality retinal imaging

VX-20 offers non-mydriatic with 45° and 27°, mydriatic and FA modes with 50° and 30° views. Additionally the VX-20 has an autofluorescence mode to provide further diagnostic investigation of the health of the retina such as AMD. Linked to VK-2 software the VX-20 provides outstanding options for fundus image analysis.

Saves space with modern, compact design

With a built in PC and high resolution camera back, this fundus camera is a versatile diagnostic tool with stand-alone capability. The VX-20 fits perfectly within the clinical environment with its single footprint, compact design.

Easy operation

The VX-20 offers enhanced functionality at the touch of a button allowing the clinician to easily switch between myd & non-myd modes. It includes a 7 inch wide, LCD colour touch screen that is simple to use and is ideally positioned to ensure easy patient observation. What’s more, the control panel has been designed in order to improve the operator experience, ensuring everything is at easy reach for the clinician.


VK-2 – High performance digital imaging software

The VK-2 digital imaging software easily captures and stores retinal photographs taken from Kowa retinal cameras well as images from other sources including a scanner. Video inputs via USB are supported with 1-click switching between instruments. Images can be magnified for viewing and filters such as red free are readily available. In FA mode the patient timer is displayed on screen and multiple timers are also available for managing several patients. A montage function creates panoramic views from multiple fundus images
