1.Introduction

Kowa VK-2 is a professional digital imaging system for ophthalmology and optometry. VK-2 offers the features you need to acquire, analyze, and store your patient image data. And because the tools you use the most are available right on the desktop, you’ll get superior results quickly and easily.

This high-resolution system supports images captured by a fundus camera and slit lamp. VK-2 also makes it possible to view images captured by other video equipment.

The VK-2 User Guide provides information about the VK-2 operations and functions. It is designed to be used as a quick reference guide. This manual assumes you are proficient in the use of a fundus camera and/or slit lamp. You should also be familiar with how to use the mouse, menus and dialog boxes, and how to open and close files.

This user’s manual describes the details to operate. But to capture and check the captured image, you only use 3 buttons [Input ID, Prev, View] (see 3.Basic Operation). That is all. It is simple to use.
