Portable Paediatric Autorefractor plusoptiX A12C
Plusoptix provides binocular, hand-held vision screening devices, especially for infants, children and uncooperative patients.
Studies show that the best visual outcomes depend on the early detection and treatment of vision disorders. Therefore, paediatric ophthalmologists recommend annual vision screening for all children starting ideally at the age of one year. If there is a family history of eye disorders, earlier screening is advised at the age of 6 to 8 months old.
Conventional visual acuity testing can only be performed in older, cooperative children.
Two healthy eyes are critical to a child’s well-being and development. A visual disorder compromises social and scholastic achievement, can be dangerous in traffic and restrict occupational choices later in life.
The Plusoptix device provides an accurate measurement within seconds and these results are compared to pre-set age-specific thresholds. After a successful measurement is completed, results are displayed to be interpreted by the health care professional.
Screenings can be performed binocularly or monocularly, ideal for kids with misaligned eyes or monocular eye conditions.
This device will generate a full report of the refraction as well as a picture the eye/s.
This device has a built-in database system, that allows you to populate the kids’ details prior to performing a measurement.
Plusoptix Screening Devices
The Plusoptix A12C range of devices detects refractive errors and eye misalignment, which are the most common causes of amblyopia (lazy eye).
Measurements are non-invasive, requiring no physical contact with the child. A sound target attracts fixation, and no further cooperation is required to perform a measurement.
Features
The measuring principle is based on eccentric photoretinoscopy: infrared light is projected through the pupils onto the retina. Depending on the refractive error, the reflected light forms a specific brightness pattern within the pupil. The spherical refraction is calculated based on this crescent pattern. To determine cylinder and axis, the same measurement is repeated in three meridians. The measurement with infrared light is completely innocuous. Infrared light is also contained in daylight and not visible.
