Automatic keratometry is a snap with the KM-500 Hand-held Keratometer.
The KM-500's unique viewing and alignment window lets you observe the targeted
eye from any distance. There is no need to dance "cheek to cheek" with your
patient.
Measurement is simple. View the eye through the window and move the KM-500
towards the eye. When the mire ring appears on the cornea, slowly move the unit
closer. The KM-500 will fire automatically when properly focused. Readings
appear instantly on the LCD display. Both left and right readings display
simultaneously.
Both the Marco Keratometer I and Keratometer II are one-position
instruments for objectively measuring corneal curvature. The Keratometer II has
the added feature of internal readings for the presbyopic practitioner or those
who prefer to work in subdued lighting where external readings are difficult.
By simply rotating the Keratometer until a major axis is located, curvatures in
both major and minor meridians can readily be measured. Marco Keratometers
assure objective accuracy in such measurements as well as in the fitting of
contact lenses. Manufactured with brass and stainless steel moving parts for
durability, Marco Keratometers incorporate such other features as precision
objectives, achromatic prisms, and uniform diffuse illumination.
Overview
The Reichert MK1
Keratometer now utilizes LED technology to provide clear, consistent
lighting, removing the need to ever change bulbs. What we didn’t change
are all the great features that have made our Keratometer the worldwide
instrument of choice by discerning practitioners for over fifty years.
A
professionally designed instrument for obtaining accurate measurements of
the corneal curvature. The convenient configuration also facilitates
measuring contact lens curvatures.
Compact Design
Easy to Use
Quick and Accurate Focusing System
Superior Optical Performance
The
TOPCON OM-4 Ophthalmometer (Sutcliff Type) is a compactly designed and
easy to use professional instrument providing precise objective
measurements of the corneal radius of curvature plus accurate
measurements of the radius of curvature of contact lenses. Instrument features include:
Internal scale reading system with extended range 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 in the field of view at
all times, thus greatly speeding up measurements
Measurement of corneal astigmatism Comeal astigmatism is easily detected. Horizontal displacement of the
mire images indicates existence of astigmatism. 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.
Speedy one-position measurement While measuring one of the principal meridians, the other principal
meridian is also measured at the same time, which means that it is not
necessary to measure both principal meridians separately in the case of
corneal astigmatism. Thus it's truly effective in reducing measuring
time, it's more accurate and also helps promote patient's cooperation.
Highly precise instrument Mire images are very sharp and easy to coincide, producing measurement
results with a minimum of individual variations.
New, Omni-Directional Joystick for unprecedented maneuverability
Easy, one-handed vertical, horizontal, diagonal adjustment improves
performance while decreasing fatigue. This is only one of the new
features that makes the TOPCON OM-4a highly desirable
ophthalmoscopic instrument for the busy practitioner.
Wide range of measurements The range of measurement is extremely wide, with the millimeter scale
covering 5.5 to 12.0mm and the diopter scale covering 60 to 28 diopters.
