1. Keratoscope

   A keratoscope, sometimes known as Placido's disk, is an ophthalmic instrument used to assess the shape of the anterior surface of the cornea. A series of concentric rings is projected onto the cornea and their reflection viewed by the examiner through a small hole in the centre of the disk. A regular-shaped cornea should show equally spaced symmetric reflections. If the patient is suffering from astigmatism or from a corneal dystrophy, the rings will be distorted. A modern development of the concept is found in corneal topography, in which analysis of the reflected image is passed to a computer. The automated instrument can produce colour-coded contour maps of the eye's topography or even three-dimensional visualisations of its surface.

1. keratoscope

   A keratoscope is a medical instrument used by ophthalmologists and optometrists to examine the cornea of the eye, particularly to measure its curvature and detect conditions such as astigmatism. It works by projecting a pattern of light onto the cornea and observing the reflection.
