HEINE Retinoscope Trainer

This model eye is ideal for teaching and practice. The pupil diameter and refractive error can be set exactly and are therefore reproducible. The front holder accepts up to two trial lenses. The cyl. can be read of the graduated scale.

  • The HEINE Retinoscope Trainer is not intended for use on patients and is not a medical product according to directive 93/42 EWG/CEE/EEC.
  • The instrument is intended as a training device for the technique of retinoscopy. It can also be used as a reference device to check the function of instruments used for refraction measurement, provided the relevant optical principles are applied. It is not designed for ophthalmoscopy, instead of this, we recommend the Ophthalmoscope Trainer C-000.33.010.
  • We are unable to give an introduction to Retinoscopy and its application in refraction in these instructions. We recommend the published literature on this subject.

Technical Description
The optics of the trainer include an achromatic lens with a pupil aperture and an orange-coloured curved shell which can be moved along the optical axis.

Technical data

  • Weight: 600 g
  • Achromat: f = 32 mm
  • Pupil size: 2, 3, 4, 5, 6, 8 mm

Using the instrument

  • Setting up the trainer: Adjust the body of the trainer so that the optical axis corresponds to your viewing axis, (angle can be adjusted by loosening screw 1).
  • Selecting refraction: Rotate the housing to select a value as shown on the scale (2). Select the desired value carefully, particularly around the 0 dpt position. View the scale from directly above to reduce the chance of error.
  • Selecting pupil size: Six different pupil sizes can be selected by rotating the selector wheel (3). Ensure that the desired value clicks into place. The selected pupil size is indicated (4).
  • Using trial lenses: A slot is provided in front of the lens to accommodate two trial lenses. The scale (6) gives an indication of the cyl. angle.
  • Retinoscopy: Please ensure that you view along the optical axis of the trainer to avoid getting a false result. You can check this by making sure that the two reflexes generated by the retinoscope on the front and back side of the trainer lens co-incide. In general, the higher the refraction, the less precise is the result.
