Keratometry

Keratometry

Keratometry is the measurement of the corneal curvature; corneal curvature determines the power of the cornea. Differences in power across the cornea (opposite meridians) results in astigmatism; therefore, keratometry measures astigmatism. It can be acquired with a variety of instruments either manually or via automated methods.

Keratometer or ophthalmometer is commonly used to identify conditions such as,

  • Evaluating degree of astigmatism.
  • Fitting of eyeglasses and contact lenses.
  • Analyzing patients having keratoconus.
  • Determining intraocular lens power for patients suffering from cataracts.
