Abstract
An ophthalmologic apparatus can measure the eye axis length of an eye to be examined and other information of the eye to be examined (for example, the cornea refractive power). In the case of the measurement of the eye axis length, when moving a detecting terminal itself by driving means, the driving means is controlled so as to slow down the speed of movement of the detecting terminal when the detecting terminal comes near the cornea of the eye to be examined.
