Device Description

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.

GMDN Terms

Code	Name	Definition	Implantable	Status
35399	Ophthalmic tonometer, line-powered	An ophthalmic, line-powered, measuring instrument used for determining the intraocular pressure (IOP) by exerting an external force against the eye which provides a reading of the resistance of the tunica of the eye to deformation (the extent of corneal indentation) which is expressed in millimetre(s) of mercury (mmHg). It typically has no contact with the eye and can use various techniques, e.g., the air-puff tonometer records deflections of the cornea from a puff of pressurized air; the applanation tonometer records the indentation pressure in thousands of a second. It is used for the diagnosis of glaucoma, designed for table top use and may provide the data on a screen and/or a print-out.	No	Active
12811	Bench-top keratometer	A bench-top, mains electricity (AC-powered) ophthalmic instrument designed to measure the curvature of the anterior surface of the cornea, particularly for determining the presence, extent, and axis of astigmatism (an error of refraction in the eye due to the cornea being unequally curved in different directions, so that rays of light in different meridians cannot be brought to focus together on the retina). It actually measures the radius of curvature in millimetres but typically displays it in dioptres. It is used mainly for contact lens fitting and for intraocular lens power determination prior to cataract surgery. This device is also known as an ophthalmometer.	No	Active
36386	Automated ophthalmic refractometer	An electrically-powered, ophthalmic device designed to be used by a healthcare professional to objectively measure the refractive error of the eye (the inaccuracies of focusing light upon the retina) by measuring how light is changed when it enters the patient's eye(s). The device emits light into the eye and detects the light reflection which is measured for sphere, cylinder, axis and/or high order aberration measurements, typically measured in dioptres (the reciprocal of the focal length of the lens expressed in metres). Also known as an aberrometer, the device uses this information to automatically calculate the lens prescription needed to correct the patient's vision.	No	Active
