C1 is a non-contact diagnostic method that measures the shape of the corneal surface, providing key parameters such as corneal curvature and refractive power. Utilizing an advanced Placido disk, it accurately captures topographical changes around the cornea and enables analysis of higher-order aberrations. This device is essential for routine ophthalmic examinations of the cornea.
A mains electricity (AC-powered) ophthalmic device used to measure the curvature and concentricity of the anterior corneal surface. It is typically a dedicated videokeratoscope that uses Placido imaging (involves a disk with concentric white and black rings) to provide keratometric and topographic measurements and images. It will typically output to a dedicated computer workstation or external computer with installed dedicated application software.
