Description
The ri-scope® retinoscope (skiascope) measures the refractive power of the eye. Errors of refraction, such as in short and long-sightedness, as well as astigmatism can be recognised and determined.

- Two models are available:
- The spot-light retinoscope projects a circular light beam.
- The slit-light retinoscope with a light beam in the form of a line, simplifies recognition and the determination of astigmatic refractive errors. The reflex in the form of a line is moved vertically to the axis across the pupils of the patient with a slight oscillating movement. The shadow moves in the same or opposite direction.
Other features include:
- Co-movement (plus lines): The patient is long-sighted.
- Counter-movement (minus lines): The patient is short-sighted.
- Simple operation with knurled thumb screw. The line and spot image can be focussed with the operating element and turned 360º, angle can be read off the integrated scale.
- Holder for hanging and fixing the fixation card into position for dynamic retinoscopy.
- Two fixation cards supplied. The patient’s eye can adjust optimally to the distance to the retinoscope.
- Integrated eyeglass protection.
- Bayonet fitting for fast and secure attachment to the handle. /li>
- Dust-tight, very sturdy and light casing made of impact resistant plastic.
- Simple exchange of the lamp at the base of the instrument head.
