For our routine eye care we use the normal range of equipment expected in any optometric practice but we have invested heavily in state of the art specialist equipment which enables us to offer a level of care previously only found in some University hospital eye departments. These would include the HRT III - Heidelberg Retina Tomography v.3, the Cerium Intuitive Colorimeter and the Optomap Retinal Scanner.
The Heidelberg Retina Tomograph
The Heidelberg Retina Tomograph (HRT) is a confocal laser scanning microscope for acquisition and analysis of three-dimensional images of the posterior segment. It enables the quantitative assessment of the retinal topography and precise follow-up of topographic changes. The most important clinical routine application of Heidelberg Retina Tomograph is the topographic description and follow-up of the glaucomatous optic nerve head.
The Ocular Hypertension Treatment Study (OHTS) has shown that HRT topographic measurements can detect structural damage up to 8 years earlier than expert assessment of stereo disc photography or visual field loss.

The Colorimeter
The Colorimeter is a logical and sequential means of exploring colour space to find the optimal Precision Tint for the relief of perceptual distortion in dyslexia, migraine and photosensitive epilepsy.
The Intuitive Colorimeter is a new optometric instrument allowing specific prescribing of tinted lenses for beneficial purposes.
We were the first paractice in the UK to have the P200C optomap, the most advanced and latest version of the optomap retinal scanner - at the time of writing there are only 4 of these machines in the whole of the UK
While eye exams generally include a look at the front of the eye to evaluate health and prescription changes, a thorough screening of the retina is critical to verify that your eye is healthy. This can lead to early detection of common diseases, such as glaucoma, diabetes, macular degeneration, and even cancer. The exam is quick, painless, and may not require dilation drops.

The Relaxed Vision Terminal
Standard spectacle lenses perform best at their centre, but they tend to distort towards their edges. The challenge of lens designers is to improve lens performance over the largest possible area. As a result lenses are increasingly more sophisticated, becoming lighter, thinner and clearer. Accurate measurement is also critical for the angle and position of the frame on the face. Leading German optical manufacturer Carl Zeiss has developed a highly advanced instrument, which measures these values with phenomenal accuracy. This unit is called a ‘Relaxed Vision Terminal’ (RVT). The RVT instrument measures to within one 10th mm. The effect of fine tuning these lens / frame parameters is to reduce and often eliminate much of the distortion spectacle lenses create. Visual comfort is improved and in turn you and your eyes feel less tired after a hard day’s work.The Zeiss Relaxed Vision Terminal for spectacle wearers who demand the best that technology can offer in pursuit of visual comfort.

Zeiss i.Profiler
Zeiss i.Profiler enhances the expertise of the eye care professional
i.Profiler analyzes the human eye with a high degree of precision and provides detailed information on the imaging properties of the human eye, in particular higher-order aberrations.
During the measurement, the i.Profiler projects a fine, low-intensity bundle of light onto the retina where it is then reflected. The aberrations of the eye result in a deformed wavefront that can then be precisely analyzed. With this technique, unlike with a traditional autorefractor, i.Profiler determines the distribution of the aberrations /defects over the entire aperture of the pupil. These measured values enable, for example, calculation of the change in refraction under different situations of use (e.g. vision in twilight or at night) and the measurement of higher-order aberrations of the eye such as coma, trefoil or spherical aberration
