The most important terms about the plusoptix devices

Adults

Can a Plusoptix Pediatric autorefractor be used in adults?

Yes, but due to the measurement technology you need to be aware of the following limitations:

  • pupil diameter needs to be between 4 and 8mm
  • media need to be clear (devices will not work in pre or post Cataract surgery patients)
  • measurement range is limited from -7.00 dpt to +5.00 dpt in spherical equivalents
  • Patients with Presbyopia will be overplused by 1,00 dpt for them not accommodating

On the other hand you will be able to obtain refraction measurements in both eyes simultaneously from 1 meter (3.3 feet) away in 0.5 seconds.

Award-winning

plusoptiX 12

Statement of the Jury:
“The friendly appearance of this auto refractometer instils trust and encourages children to get involved in the examination in a playful way.”

plusoptiX 16

Statement of the Jury:
“A lovely tool that takes focuses not only on technology and ergonomics in its design, but also the needs of the child being treated. This makes the examination a more pleasant experience for everyone involved.”

Baseline refraction

What is a baseline refraction?

In the context of an entry examination a quick assessment of a patient’s refraction by means of a Plusoptix Pediatric autorefractor measurement is helpful. Plusoptix devices are designed to be used in undilated pupils in order to save time. As a consequence, all measurements of hyperopia are likely to be under estimated due to accommodation. However, measurements of myopia, astigmatism, axis, anisometropia and gaze asymmetry are accurate due to the fact that both eyes are measured simultaneously from a distance of 1 meter (3.3 feet) away. A refraction measurement in un-dilated pupils will provide you with a baseline refraction as a starting point for your cycloplegic retinoscopy. A baseline refraction must not be used for the prescription of glasses or contact lenses.

Children

Can Plusoptix Vision Screening devices be used in adults?

Children may have a vision disorder that causes Amblyopia. According to the National Eye Institute, Amblyopia is the leading cause of monocular vision loss in children. Amblyopia is no longer a risk in a fully developed adult eye. Therefore it is crucial that children are screened for vision disorders. Plusoptix Vision Screening devices may be used in adults. However, the leading cause of vision loss in adults is Glaucoma. Glaucoma is an eye disease that you can’t detect with any device that is taking refractive readings. This is why Plusoptix doesn’t market its vision screening devices for adults.

Electronic Medical Record (EMR)

Can I connect the device to my Electronic Medical Record (EMR)?

As an alternative to the manual entry of the patient data, Plusoptix devices can also be connected to your Electronic Medical Record (EMR).

Eye care (professional)

Am I an eye care professional?

For the use of a Plusoptix autorefractor you are considered to be an eye care professional if you are or work for an ophthalmologist or an optometrist. Another group of eye care professionals are Orthoptists. Generally speaking you can consider yourself an eye care professional if you know what a refraction is and if you can tell a good refraction from a bad refraction in children.

Free software updates

Harmless

Is the illumination technique of Plusoptix really totally harmless to the child's eyes?

Vision screening based on photoscreening technology requires a flash light. To be cleared as a flash light in photoscreening technology, a device has to fulfil the requirements of relevant standards, e.g. DIN EN ISO 15004-2, DIN EN 62471 etc.

Vision screening devices by Plusoptix meet all relevant standards, and have passed independent testing. At Plusoptix guaranteeing the safety of patients and users is our main priority. The illumination technique used by Plusoptix, is totally harmless to the child's eyes.


Plusoptix devices can be recognized by the proprietary Plusoptix Smiley face.

The use of a flash light may mistakenly be considered to be harmless. But depending on the intensity, and quality of light emitted by a flash light, it can be a danger to the retina. Possible eye damages, caused by flash light that does not fulfill these relevant standards, include conjunctivitis, corneal blindness and lens opacity. Practitioners, using devices with flash light that does not fulfill relevant standards, need to be aware of possible irreversible damages to the eyes as well as possible recourse claims.

Silver sticker

Where do I find the type label?


You will find the S/N of your device on a silver sticker next to the battery compartment (battery powered devices) or on the bottom of the cradle (stationary devices).

Vision disorders

What’s a vision disorder?

Vision disorders prevent children from having good vision with both eyes. They don’t hurt and children usually don’t realize that they can’t see clearly with both eyes. If vision disorders are undetected and untreated they may cause Amblyopia (lazy eye). Plusoptix Vision Screening devices detect the following vision disorders in children 6 months and older:

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

Where and when can I purchase a warranty extension?

We offer warranty extensions for all Plusoptix models that are still available for purchase today. We kindly ask you to contact us by e-mail (please remember to share with us the serial number (S/N) of your instrument).
