Keratoscope

Keratoscope is a medical instrument used in the field of Ophthalmology to examine the cornea of the eye. It is primarily used to diagnose and monitor conditions that affect the shape and surface of the cornea, such as keratoconus and corneal dystrophy.

History

The keratoscope was first introduced in the 19th century by the French ophthalmologist Antoine Claudet. It was initially used to measure the curvature of the cornea, but its use has since expanded to include the diagnosis and monitoring of various corneal conditions.

Function

The keratoscope works by projecting a pattern of light onto the cornea. The reflection of this pattern is then analyzed to determine the shape and surface of the cornea. This information can be used to diagnose conditions such as keratoconus and corneal dystrophy, as well as to monitor the progress of these conditions over time.

Types

There are several types of keratoscopes, including the Placido disc keratoscope and the videokeratoscope. The Placido disc keratoscope uses a series of concentric rings to project a pattern onto the cornea, while the videokeratoscope uses a video camera to capture images of the cornea.

Clinical Use

In clinical practice, the keratoscope is used to diagnose and monitor a variety of corneal conditions. It is also used in the fitting of contact lenses, as it can provide detailed information about the shape and surface of the cornea.
