Automatic Refractor And Keratometer

An Automatic Refractor and Keratometer is a combined instrument used in ophthalmology to measure the refractive power of the eye and the curvature of the cornea.

The Automatic Refractor measures the refractive error of the eye, which includes the measurement of nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It uses a series of lenses and a light source to determine the eye's focusing ability.

The Keratometer, on the other hand, measures the curvature of the cornea, which is the clear front surface of the eye. It helps in diagnosing conditions such as corneal astigmatism and irregularities in the corneal shape.

By combining these two functions into one instrument, the Automatic Refractor and Keratometer provides comprehensive information about the eye's refractive status and corneal shape. This information is crucial for determining the appropriate prescription for eyeglasses or contact lenses, as well as for planning refractive surgeries such as LASIK.

In the supply class Ophthalmic Instruments, Equipment, and Supplies, the Automatic Refractor and Keratometer is an essential tool for eye care professionals, including optometrists and ophthalmologists. It falls under the broader supply group of Medical, Dental, and Veterinary Equipment and Supplies, as it is used in the medical field for diagnosing and treating eye conditions.
