TOPCON-OPHTHALMOMETER MODEL OM-4

FEATURES:
Internal scale reading system.Besides the mire images, the millimeter scales for the radius of curvature and the diopter scales for the corneal refractive power, of both vertical and horizontal axes are viewed at all times in the field of view,thus greatly speeding up meaurements.

Measurement of corneal astigmatism.

Horizontal displacement of the mire images indicates existence of astigmatism and the axis rotating handle is used to coincide the measuring head with the axis, after which the vertical and horizontal knobs are used to coincide the mire images, showing the great ease and simplicity of one position measurement.

One position measurement is not only more accurate but is truly effective in reducing measuring time and also helps promote patient's cooperation.
