10.5 Patient data
From version 5.0_170911 and above 2WIN uses the age of the patient information as a
corrective parameter for determining the patient refraction. This information is used in
particular to compensate accomodation in young patients with hyperopia-based refraction
error. Please take care of selecting the age of the patient (long press the "RIGHT" joystick
button) before making the measurement.
The age can be modified also after the measurement is acquired by the 2WIN, but it is
mandatory to select it before saving the patient data. As already described before, when the
operator saves the measurement (long press the "PRINT" button) he is certifying that the
patient information (age and optionally name and surname) are correct. Please take into
consideration that by default the patient age range is set to 15-50 years.
10.6 Browsing Mode
The browsing mode allows to recover patient's data previously saved in the 2WIN SD
memory. Holding the down button in the Home window, the Browsing mode is entered. The
UP and DOWN buttons permit to move between different patients: the data (Patient number,
name, date of birth, Age Selection, exam date) is shown for some seconds and then
disappears. However, patient data can be recalled by pushing the left button. When the list
of patients is at the end of the browsing, the display restarts from the first patient and a
circular-shaped arrow icon appears.
If a stored patient data has been saved with a 2WIN software version previous to 2.0 (but
not lower than 1.4), then the browsing mode shows an exclamation point icon indicating that
some fields are incomplete.
It is possible to add a filter in the patient name and / or number for the search of a specific
patient by pressing the Button D; if filter is inserted, an icon shows that the filter is active.
If an error occurs during the measurement and the message appears, this last message can
be recalled by holding the button C.
