The keratometer measures the corneal curvature, and gives the corneal refractive power, axis of the corneal meridian, and corneal cylindrical power. (Increments: 0.12 & 0.25 D) Extensive measurement modes refraction and keratometry, sophisticated fine manual control when measuring cataract.We record refractions like this: -2.00 - 1.75 x 180, where the "-1.75 x 180" means the -1.75 of extra cyl power has an axis of 180º, which means this power Meaning of caution sign Continuous keratometry and refractometry - [K/R] mode The complete user manual is available on a web space. A keratometer using a microprocessor computer to facilitate the rapid measurement of the corneal curvature. Such instruments usually provide measurements of Readings from a manual keratometer and an automated hand PATIENTS AND METHODS Mean-difference plots were performed self-contained hand-held machine that
