BEFORE USE

1.1 Outline of the device

AUTO REF/KERATO/TONOMETER Model TONOREF II is designed to singly perform objective

refraction, corneal shape measurement, and non-contact tonometry measurement by incorporating a

standard auto ref/keratometer and non-contact tonometer into one unit.

The objective refraction function measures spherical powers, cylindrical powers and cylinder axis. The

corneal shape measurement function measures the radius of corneal curvature (corneal refractive

powers), the direction of the steepest meridian, and the amount of corneal astigmatism.

The non-contact tonometry function measures the intraocular pressure without contacting the eye.

Refraction is mainly performed as a reference for lens prescription for correction of visual acuity using

spectacles and contact lenses.

The corneal curvature radius measurement is performed mainly for the following purposes:

• To prescribe lenses for correction of visual acuity using contact lenses

• To determine the power of intraocular lenses to be implanted after cataract surgery

• To conduct postoperative follow-up of corneal shape

Tonometry is performed for the early detection of glaucoma, and for preoperative examination and

postoperative care in ophthalmology.

This device is an integral type with a main body mounted on a base.

A chinrest is mounted on the base on the patient’s side.

An LCD panel, control buttons, joystick and a printer are attached on the main body to conduct align-

ment and perform operations. Inside the device are units for performing AR/KM and NT measure-

ments, which can be operated by simply pressing a button/switch.

In addition to the above, the device also offers the following features:

• A space-saving concept that allows AR/KM and NT measurements to be performed by a

single device which saves space and eliminates the need for the patient to move between

two devices.

• An auto-tracking mechanism is provided. The device automatically controls the up-and-

down and back-and-forth movements for alignment and focusing.

• An auto-shooting function is provided. Measurements take place automatically when the

device is best aligned and in focus.

• An APC function that measures the intraocular pressure with the minimum necessary pres-

sure of puffed air.

• A motorized up-and-down chinrest allows the operator to adjust the height of the chinrest.

• A built-in RS-232C interface allows data export to computers etc.
