Auto Ref-Keratometer with
High Resolution Touch Screen
PRK-6000 by Potec
Refraction & Keratometry Measurement
The PRK-6000 provides and extensive dioptric meaurement range (-25D to +22D), and the radius of curvature for keratometry is 5.0mm to 10.2mm. Easy alignment and friendly operation allows you to measure the refraction and keratometry in sequence, and the results can be validated immediately. Due to its easy alignment and friendly operation you can measure the refraction and keratometry in a sequence and the results can be checked all at once.
Peripheral corneal curvatures can be measured by having the examinee look at the peripheral eye fixation lamps. Measuring the corneal periphery will help you examine irregular astigmatism, and also determine a better fitting for a contact lens.
Introduction of various meaurement systems of the
PRK-6000 enables location of even minor eye disorders.
Intutive Diameter Meaurement
Using the freeze function, measurement of the diameter of the cornea, pupil or hard contact lenses worn by the patient can be per-formed. By simply touching and dragging the screen with your finger measurements are exactly calculated.
TFT-LCD with Touch Screen
By adopting high resolution VGA TFT-LCD with Touch Screen function, we virtually removed all input keys except the measurement button on the Joystick and Chinrest control switches. Tests are preformed rapidly and conveniently by simply pressing a button or the icon indicated on the screen.
Instant Display Data
By simply touching the icon on the screen results of up to 10 measurements stored in memory can be viewed or printed b ythe built in thermal auto cut-off printer.
Ineractive SETUP Change
Simply touch the icon on the screen and changed setting can be seen. The touch screen supports the interactive settings changes quickly and conveinently saving user time innovatively.
When refraction results in an error reading due to an intraocular lens or cataract the mesurement can be performed with the IOL icon switched 'ON'
The chinrest is motorized with the use of a switch conveniently positioned for the operator. This makes for
simple adjustment of the chinrest from patient to patient.
Printerwith Auto Cutter Function
Simply touch the "PRINT" icon on the screen and the PRK-6000 will immediately provide a complete printout of the measurement results. An Auto Cutter is provided for convenience.
Data can be transferred to external devices (personal computer, etc.) via an RS-232 interface. A USB interface is also provided for future compatibility.
