Simple explanation, subject to the original. It has the date and time on it. PD is the pupil distance (60mm), KRT data corneal curvature data, R right eye, D corneal curvature diopter, mm corneal curvature radius millimeter, and A corneal axial direction. H corneal horizontal direction, v corneal vertical direction. The horizontal (H) curvature of the right cornea is 42.25D, the radius of curvature is 8.0 1, and the axial direction is 5 (nearly horizontal). The vertical (V) curvature of cornea is 42.75D, the radius of curvature is 7.90mm, the axial direction is 95 (nearly vertical), the average (ave) corneal curvature is 42.50 D, and the radius of curvature is 7.96. Astigmatism myopia astigmatism 50 degrees, axial 5. The following are two different axial tests, with small error and high reliability. We use 7.96 as the radius of curvature of the right eye. L stands for left eye, everything else is the same, so I won't go into details. In fact, if you give the data to the optician, they will know how to deal with it.
