The plusoptiX A09 is a binocular handheld
autorefractometer named "Emily".
1) Application
In a matter of seconds, the plusoptiX A09
simultaneously measures the refraction of
both eyes (binocular) at one meter distance
from the child.
The measured values correspond to the
results of a retinoscopy in un-dilated
pupils.
The measurement can also be executed in
cycloplegia. However, it is to be noted that
the pupils do not become larger than 8 mm in
diameter. One diopter must be extracted from
the measured refraction values. This
correction is required because the plusoptiX
A09 is designed for measurements in miosis.
One diopter for accommodation at one meter
distance is to be considered in the
measurement result.
2) Advantages
The measurement at one meter distance is
reliable and delegable. Even children with
nystagmus and uncooperative patients can be
measured in less than one second with the
plusoptiX A09. It is possible to measure
refraction over already existing glasses or
contact lenses. If a retinoscopy in
cycloplegia is necessary, it proceeds
quickly due to the existing measurement
values, especially from cylinder and axis,
and you have a comparison value. The
plusoptiX A09 considerably simplifies the
initial examination of babies and toddlers
in your practice.
3) Measurement results
Refraction (sphere, cylinder and axis)
Symmetry of corneal reflexes
Pupil diameter and pupil distance
The one meter measurement distance prevents
the usual device accommodation with
autorefractometers and therefore delivers no
false myopic results.
How does the
plusoptiX A09 differentiate itself from
other autorefractometers commercially
available today?
1. The plusoptiX A09 measures the refraction
in sphere, cylinder and axis for both eyes
simultaneously (binocular).
Advantages:
a) An anisometropia is easily diagnosed
even without dilating drops.
b) Risks of possible side effects from
dilating drops are eliminated.
2. The measurement occurs at one meter
distance without any contact.
Advantages:
a) No device myopia arises during the
measurement at one meter distance.
b) Pleasant for child, parents and examiner.
The child remains under
parents' care during the measurement and
therefore has no anxiety.
3. The measurement is fully automated and
takes only seconds.
Advantages:
a) The measurement can be delegated.
b) If there is no vision disorder, the
parents' length of stay in your practice
with their children is thereby decreased to
a few minutes.
4. Both eyes' corneal reflexes are
recorded simultaneously during the
measurement.
Advantages:
a) Line-of-sight monitoring during the
measurement prevents false measurement
results.
b) Non-symmetrical corneal reflexes can be
an indication for strabismus.
5. The pupils of both eyes are shown on
the monitor during the measurement.
Advantage: Central located media opacities,
like cataracts, are clearly diagnosable
6. In addition, the pupil diameter of
both eyes and the PD are also indicated.
Advantage: An anisocoria is easily
diagnosable.
