Paediatric Autorefractor Devices for Optometrists and Ophthalmologists

plusoptiX has designed handheld autorefractors for babies, children and uncooperative patients that measure the refraction of both eyes (binocular) from one-meter distance within one second.

The devices are used on undilated pupils, and provide eye care professional with a reliable baseline refraction in the context of an initial exam, to identify false-positive referrals.

If a cycloplegic retinoscopy is required, the baseline refraction provides a valuable starting point for myopia, astigmatism and axis measurements. Performing a cycloplegic retinoscopy with these measurements at hand is quick and easy, thus saving precious chair time.

Features:

  • Binocular readings with simultaneous measurement of both eyes
  • Monocular readings (e.g. in strabismic or aphacic patients)
  • Measurement from 1m distance to the child
  • Measurement in less than one second
  • Can be used on undilated pupils
  • Fully automated function
  • Children can be measured starting at 6 months of age
  • Measurement is delegable and can easily be performed by an ophthalmic technician
  • Possibility to measure over glasses and contact lenses
  • Child friendly design
  • Can also be used in cycloplegia under certain conditions

The plusoptiX A12C and A12R are battery operated devices and can easily be used in multiple exam rooms. Each plusoptiX device measures both eyes simultaneously and provides reliable measurement values of refraction, pupil diameter, interpupillary distance and symmetry of corneal reflexes. With the binocular measurement anisometropia and anisocoria can be detected immediately.

Used in undilated pupils, measurements of hyperopia, myopia, astigmatism and anisometropia provide valuable data for a quick vision examination. Results can additionally be used as a starting point for retinoscopy or to confirm retinoscopic results.

The measurement from one-meter distance is reliable and clinically proven. Even children with nystagmus and uncooperative patients can be measured within seconds.

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.

Screening results

plusoptiX devices provide reliable measurement values of:

  • Refraction (Sphere, Cylinder, Axis)
  • Pupil diameter and pupil distance
  • Symmetry of corneal reflexes

With these measurement values it is possible to detect e.g. following most prevalent childhood vision disorders that may lead to the development of amblyopia (lazy eye) including:

  • Hyperopia (farsightedness)
  • Myopia (nearsightedness)
  • Astigmatism (blurred vision)
  • Anisometropia (unequal refractive power)
  • Anisocoria (unequal pupil size)
  • Strabismus (eye misalignment)

With help of the measurement picture it is also possible to detect cataracts or corneal scars.
