C-Quant

The Benefits

• The C-Quant is computer-controlled, so examination data and results can be saved
• The examinations are conducted monocularly
• The inclination angle of the unit can be adjusted to suit the patient’s requirements
Show More
An instruction phase at the beginning of the examination enables the examiner to determine whether the patient has understood the process
Corrective lenses can be inserted
At the end of the examination, all of the patient’s answers are shown in the flow chart, together with the result.
Reliability indicator for quality control purposes

Presentation of the Results

• Absolute straylight value as a log(s)
• Graphic display of the straylight compared to an age-related normal examination time
• Standard deviation of the individual measuring points (Esd)
• Reliability coefficient (Q)
• Printout possible

Cause

Increased ocular straylight is almost always caused by a lens cataract, but can also be caused by the cornea too, e.g. after refractive surgery.
In short: Increased ocular straylight reduces visual acuity and thus impairs the quality of life.

Examination

The examination with the C-Quant is specifically designed for older patients and those with reduced visual acuity and takes approx. 1 to max. 2 minutes per eye.
