Features
The Canon Digital Retinal Camera CR-2 Plus AF takes digital photographic retinal images of patient’s eyes across an angle of view of 45 degrees, in a naturally dilated state without using mydriatics. The CR-2 Plus AF has the following features:
AF (Auto-focus) and AS (Auto-shot) functions
CR-2 Plus AF is equipped with Auto-focus and Auto-shot functions. Those provide significantly improved ease-of-operation.
A wide range of ISO speed settings
The CR-2 Plus AF can take color images at a wide range of ISO speed settings from ISO 200 up to ISO 1600 as the standard flash intensity. In photography at ISO 3200/6400, applying low flash intensity mode can reduce patient discomfort caused by light glare.
Compact, user-friendly design
The CR-2 Plus AF is designed to be small, lightweight, and compact. This makes it easier to assist patients. An operation lever has the integrated functions: vertical movement of the main unit, switching between anterior segment and fundus, and manual focusing. This lever significantly improves alignment operability.
Fundus Autofluorescence Photography
(FAF) photography can be performed in non-mydriatic.
Special digital camera
The CR-2 Plus AF is equipped with a special digital camera using EOS digital technology. The enhanced Canon technology enables the CR-2 Plus AF to fully maximize its capabilities for shooting high-quality, high-resolution diagnostic images.
Small pupil photography function
The CR-2 Plus AF captures retinal images through pupils of the normal diameters from 4.0 mm. This small pupil photography function permits image to be captured through pupils from 3.3 mm in diameters.
System optimized for digital photography
With the supplied imaging control software, the photographed images can be browsed, processed, stored, output to the DICOM storage server, exported in DICOM or JPEG format and sent to a printer. In this manual, the operation procedure is described with the Retinal imaging control software NM 2 (referred to as “Rics NM 2”).
Indications for Use
For USA
The CR-2 Plus AF is intended to be used for taking digital images of the retina of the human eye without a mydriatic. The CR-2 Plus AF has the following photography modes: color, red free and cobalt digital filter, and fundus autofluorecence (FAF).
4
For European Union
This medical device is intended to observe and record images of retinal fundus through the pupil without making contact with subject’s eye for the purpose of diagnosis by way of producing fundus image information.
