This invention is intended to provide an ophthalmological instrument capable of measuring in a non-contact way the intraocular pressure of an eye to be examined and capable of measuring the radius of curvature of the cornea of the eye to be examined. The ophthalmological instrument of the invention can measure both the intraocular pressure and the shape of the cornea with a single set of apparatus without using a dedicated ophthalmological instrument for each measurement as has been employed in the prior art technique. The instrument of the invention includes non-contact type intraocular pressure measurement means for measuring the intraocular pressure of the eye to be examined by ejecting fluid onto the cornea of the eye and means for measuring the radius of curvature of cornea by projecting a predetermined index to the cornea of the eye to be examined and measuring the radius of curvature on the basis of the cornea reflection image of the index, whereby both means are assembled integrally in the apparatus. |
