The Topcon OM-4 ophthalmometer (Sutcliff Type) is a compactly designed and easy to use instrument providing precise objective measurements of the corneal radius of curvature plus accurate measurements of the radius of curvature of contact lenses.

The OM-4 Features Easy to Align Mire Images.
All readings are thus placed in one field of view, greatly simplifying and speeding up measurements. Extended range of curvature readings possible from 5.5 mm to 12.0 mm.

Contact Lens Measurement
Replace the chin-rest with the supporting column and place the contact lens holder, with the contact lens attached to it, on top of the column. It will be possible to measure the radius of curvature of the concave or convex face, depending on which faces the instrument, in the same manner as when measuring the cornea.
