The TrueField® Analyzer (TFA) heralds a new era in visual field testing. It combines objectivity with “non-contact” ease of use, making it easy for technicians and patients, and gives clinicians objectivity in assessing their patient’s condition. Assessing both eyes concurrently the TFA test is fast (just 4 minutes
total measurement time for both eyes) and exploits the consensual light reflex to further improve accuracy
by considering bilateral asymmetries.
Most importantly the TFA makes objective perimetry a clinical reality.
TFA – objective perimetry made fast and easy.
The TFA brings together advanced multi-focal stimulus and analysis methods with real time computer
vision pupil monitoring to realize the dream of objective pupil perimetry. Initially developed over 15 years agoi
and subsequently demonstrated in multiple laboratoriesii, pupil perimetry is based on measuring involuntary
pupil diameter changes in response to retinal visual stimulation.
By combining advanced sparse stimuliiii, regressive multi-focal methodsiv and automated real-time computer vision pupil monitoring, the TFA moves pupil perimetry from the laboratory into clinical practice.

The new Henson 8000 perimeter has the multiple and single supra-threshold programs associated with the Henson range but also has threshold tests that meet and, in some cases, exceed current instrument performance.
With over 25 years’ experience of manufacturing perimeters in the UK, we are using the latest generation of white LEDs for the 8000. More stable and energy efficient than filament lamps, they have an exceptionally long life in addition to solid-state technology that gives you fast accurate results and standard format printouts. Like its predecessor, the Henson 8000 offers the Estermann and UK driving test (DVLA approved), has been tested to ISO 12866 and is CE and FDA approved.

Remarkably small in size yet reassuringly abundant in features, the Henson Compact can actually test out to an eccentricity of 72 degrees. Weight, ease of use, performance and speed of operation have all influenced
its design. Additionally, important clinical considerations have now been incorporated such as a new threshold algorithm which enhances the reliability and reproducibility of threshold levels together with automatic measurement of patient response time. These two factors are now believed to have important significance in the reliable detection and monitoring of Glaucoma conditions. Whatever your visual field requirements, from quick routine screening to longer term monitoring, the Henson 6000 range has been designed to meet these requirements in a compact and easy to use screener.

The Rodenstock AL4600 automatic lensmeter is a fully-functioned high-quality instrument that is perfect for the ophthalmic practice or workshop. With many innovative functions this instrument provides everything you need in a lensmeter, including UV measurement.
Features include the following:
* Automatic measurement and data storage
* Automatic measurement of progressive (varifocal) lenses
* Measurement of UV permeability
* Measurement of pupil centres
* Contact lens mode
* High definition backlit colour touch-screen
* Extended measurement range of -80 to +80 dioptres
* Calculation of resulting prism
The ergonomic design of the AL4600 makes operation a delight, with most operations made by use of the colour touch-screen. A special automatic measuring mode saves the data as soon as the lens is correctly aligned, and also enables the automatic detection and measurement of progressive (varifocal) lenses. The clearly structured Centering Assistant helps the operator to centre the lens correctly.
In prism mode the data are analysed in cartesian and polar coordinates, as well as the deviation from the optical centre. The ABBE number can be set to meet specific requirements.
A built-in thermal printer provides a hard copy of measurement data, whilst a serial RS-232C interface provides possibility for electronic data transfer to a host computer system or auto-optometry system.
The UV transmission measurement is displayed on the screen using an easily understood bar graph display.
