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.
Choice of XL 3.5 V xenon lamp or HL 2.5 V halogen lamp.
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.
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.
Dust-tight, very sturdy and light casing made of impact resistant plastic.
Simple exchange of the lamp at the base of the instrument head.
