Topcon TRK-3 OMNIA - Introduction

1
INTRODUCTION
Thank you for purchasing the TOPCON AUTO KERATO-REFRACTO TONOMETER TRK-3
OMNIA.
INTENDED USE
TRK-3 OMNIA is a combination of the auto refractometer, keratometer, non-contact tonome-
ter, and pachymeter. The device is indicated for automatic measurement of the refractive
errors of the eye; measurement of the corneal curvature of the eye; measurement of intraocu
-
lar pressure without contacting the eye; and measurement of central corneal thickness.
INDICATIONS FOR USE
(1) Refractometer
TRK-3 OMNIA is indicated for measuring spherical refractive power, cylindrical refractive
power, astigmatic axial angle of the eye to aid identifying refractive errors.
(2) Keratometer
TRK-3 OMNIA is indicated for measuring corneal curvature radius, corneal refractive power,
corneal astigmatic axial angle of the eye to aid in identifying corneal abnormalities and changes.
(3) Tonometer
TRK-3 OMNIA is indicated for measuring intraocular pressure without contacting the patient to
aid in the monitoring of intraocular pressure for diagnosis of ocular health and diseases.
(4) Pachymeter
TRK-3 OMNIA is indicated for measuring central corneal thickness of the eye to aid in identify-
ing corneal abnormalities and diagnosing ocular health and diseases.
CLINICAL BENEFITS
This device is designed to measure objective refractive error and corneal curvature of the eye
and provide them as preliminary data for subjective eye examinations.
Providing preliminary data for subjective eye examinations will help shorten the time required
for subjective eye examinations, reduce the burden on patients, and improve the accuracy of
test results. Appropriate eyeglass prescription improves the quality of the patient's daily life.
The device is also used to measure intraocular pressure and central corneal thickness. Non-
contact measurement of intraocular pressure and central corneal thickness can be provided to
the user (doctor) to assist in disease diagnosis and patient management.
FEATURES
This instrument features the following:
• The position of the control panel can be adjusted to accommodate the user's preferred position.
• An alignment is performed automatically by auto alignment function.
• The measurement results can be output to a personal computer (PC), etc.
