of the present manual before operating the device.
•
The 2WIN-S is a stand-alone binocular vision analyzer. It measures refraction of both eyes at the
same time.
•
The 2WIN-S should not be confused with a table-top auto-refractometer (AR). ARs are designed to
measure refractive errors of one eye at time, in an artificial condition of far fixation.
•
Please familiarize yourself with the measurement conditions and techniques of the 2WIN-S in order
to exploit its full potential.
6.1 Main Applications
•
The 2WIN-S is a stand-alone binocular vision analyzer. It
detects a patient’s real
-time refraction.
•
It is a binocular instrument that measures refraction on the basis of eccentric infrared (IR) photo-
refraction (also photo-retinoscopy). Both eyes are measured at the same time, while fixating at 1
meter.
•
It is battery operated, non-invasive, fast, and easy to use.
•
It automatically measures binocular refraction, pupil distance, pupil size, direction of gaze, and
fixation abnormalities.
•
Binocular refraction of children from 3 years of age to seniors.
•
Early detection and documentation of multiple amblyogenic factors.
•
Over-refraction of contact lenses.
•
OPTIONAL (APP), CR-App: phoria/tropia measurements.
•
PLUS package (2WIN-S
Plus
):
•
CR-App: phoria/tropia measurements;
•
AI-App: anterior segment screening warning customers of possible pathologies of the
anterior segment;
•
Personalized tablet;
•
EMR connection.
6.2 Exam conditions
The device should be paired with a tablet through Wi-Fi or Bluetooth connection, depending on the model.
