Riester Ri-Scope Retinoscope Head 3.5 V

Riester Ri-Scope Retinoscope Head XL 3.5 V

The ri-scope retinoscope (skiascope) measures the refractive power of the eye. Refractive flaws, such as near- and far-sightedness, as well as astigmatism can be detected and diagnosed.

• With 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 detection and diagnosis of astigmatic refractive flaws.

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. A shadow moves in the same or opposite direction.

• Co-movement (plus lines): The patient is far-sighted.
• Counter-movement (minus lines): The patient is nearsighted.
• Easy to operate with knurled thumb screw. The line and spot image can be focussed with the controls and turned 360º, angle read-out displayed on the integrated scale.
• Holder for hanging and placement of the fixation card into position for dynamic retinoscopy.
• Delivered with two fixation cards. The patient’s eye can adjust optimally to the distance to the retinoscope.
• Integrated eyeglass protection.
• Bayonet fitting for quick and secure attachment to the handle.
• Dust-proof, very sturdy and light casing made of impact-resistant ABS plastic.
• Bulbs can be quickly replaced at the base of the instrument head.
• Large selection of power sources: handy and stable handles, practical chargers and well-conceived diagnostic stations
