Plusoptix A20Z Pro – handheld, binocular pediatric autorefractometer
The Plusoptix A20Z Pro is a modern, handheld, binocular autorefractometer, which has been specially developed for the vision examination of infants and young children. The device is one of the outstanding tools of modern pediatric ophthalmology screenings, which provides fast, objective and reliable results even in patients requiring minimal cooperation.
The use of the device plays a significant role in the early detection of vision problems in childhood, especially with regard to the screening of amblyopia (blurred vision) and hidden refractive errors. Early diagnosis allows for timely treatment, which contributes to the improvement of children’s learning abilities and quality of life in the long term.
Operating principle and measurement characteristics
The device uses technology based on infrared skiascopy, which provides a fast, contact-free and completely comfortable examination for the child. Thanks to the binocular measurement principle, the examination is performed on both eyes simultaneously, under natural visual conditions.
The Plusoptix A20Z Pro:
uses a binocular measurement method
non-invasive, contact-free operation
does not require pupil dilation
can be used from the age of 6 months
The measurement is performed at a working distance of 1 meter, which allows the child to remain in close proximity to the parent, even on their lap, thereby significantly reducing the examination stress and increasing the success of the measurement.
Fast and complex diagnostic measurement
The device operates extremely fast, the measurement can be performed in an average of 1–2 seconds. Several important parameters are determined during a single measurement cycle:
spherical and cylindrical refractive errors
axis position
pupil diameter
pupillary distance (PD)
gaze direction
testing of eye cooperation
The system is suitable for detecting microstrabismus (fine strabismus) and is an extremely effective tool in screening amblyopia.
User-friendly design
The Plusoptix A20Z Pro is designed to simplify everyday clinical use:
automatic measurement start
intuitive user interface
built-in computer
optional external monitor and wired measurement unit
Sound and light-based fixation signals (colored LEDs) help maintain the child’s attention, which increases measurement accuracy and test success.
Advanced system integration (Pro version benefits)
The Plusoptix A20Z Pro model stands out from the traditional versions with its advanced digitalization and integration capabilities:
WIFI connection for fast data transfer
EMR system integration (electronic patient record management)
large internal database (for storing up to tens of thousands of patient data)
measurement data export and network sharing
automatic measurement distance feedback, which helps to achieve accurate and reproducible measurements
These features significantly facilitate institutional data management and ensure the smooth integration of the device into existing IT systems.
Documentation and data management
The device offers extensive documentation options:
patient data record system
printing examination protocols
printing self-adhesive labels (for cardboard)
digital archiving and retrieval
This supports efficient administration and long-term follow-up examinations.
