With the Ultra-Widefield objective lens, the
“Focus” value is adjustable in increments of two
diopters
In comparison, the “Focus” value is adjustable in
steps of 0.25 diopters with the SPECTRALIS
standard objective lens.
The focus range for a properly-focused image
acquired with the Ultra-Widefield objective lens
is significantly larger than with the SPECTRALIS
standard objective lens
Therefore, the displayed “Focus” value in the
“Settings” section is not reliable and may vary
significantly from the patient’s actual refraction.
