AdaptDX Adaptometer (measure dark adaptation in participants at risk of developing age-related macular degeneration):

 ‌ Quickly and easily measures dark adaptation, which is dramatically impaired at the earliest stages of macular degeneration.

Bailey-Lovie Word Reading Chart:

   

The Bailey-Lovie Reading Chart Set includes 5 charts which show different word sequences on a plain white surface and features over 17 different sizes of text equivalents from N2 to N80.

Binocular Indirect Ophthalmoscope (Keeler):

 

Constitutes a light attached to a headband, in addition to a small handheld lens. It provides a wider view of the inside of the eye. Furthermore, it allows a better view of the fundus of the eye, even if the lens is clouded by cataracts.

Canon CF-1 Colour Fundus Camera (limited availability):

 ‌

Versatile 50° retinal camera with 4 photography modes; Color. FAG, RedFree and Cobalt. Required pupil diameter as small as Ø 5.2 mm , even Ø 4.3 mm in SP Mode!

ETDRS LogMAR Chart:

 

ETDRS acuity testing has become the worldwide standard for visual acuity testing, designed to eliminate inaccuracies in the Snellen tests.

Goldmann Tonometer:

‌ ‌

Device fixed to a slit-lamp microscope that is used to measure intraocular pressure.

Heidelberg Spectralis HRA and OCT (limited availability):

‌ ‌

Multi-modality imaging with SPECTRALIS® is helping drive the development of novel therapeutics and changing the course of patient management in eye care. Using an upgradeable platform approach, SPECTRALIS has enhanced the role of spectral domain OCT by integrating it with confocal scanning laser ophthalmoscopy (cSLO). The combination of these two technologies has enabled new imaging capabilities, such as TruTrack™ Active Eye Tracking, and BluePeak™ blue laser autofluorescence, providing clinicians with unique views of the structure and function of the eye.

Heidelberg Spectralis HRA and OCT 2:

‌As Above* ‌‌

As above with OCT-angiography and wide-field lens.

Humphrey Field Analyser:

Humphrey automated visual field analysers are the gold standard in perimetric testing. They have a 25 year proven track record in visual field development and research.

Humphrey Matrix 800:

 ‌‌

Humphrey Matrix® 800 for early visual field loss detection proven to find early visual field loss quickly and easily.

Lensmeter / Focimeter GJD:

‌ ‌

Ophthalmic instrument used by optometrists and opticians to verify the correct prescription in a pair of eyeglasses, to properly orient and mark uncut lenses, and to confirm the correct mounting of lenses in spectacle frames. Lensmeters can also verify the power of contact lenses, if a special lens support is used.

Lenstar Optical Biometer:

‌ ‌

In a single measurement, provides accurate axial dimensions of all of the eye’s optical structures, and measures corneal curvature.

MAIA Microperimeter (x2):

 ‌

MAIA provides concurrent analysis of structural and functional aspects of the retina. Combining Scanning Laser Ophthalmology (SLO) fundus imaging, retinal sensitivity mapping and fixation analysis in one exam, MAIA microperimetry is a powerful tool to detect, describe and follow up pathologies affecting the macula, where visual acuity and conventional visual fields are inadequate.

Metrovision MonCvONE Standard Automated Perimeter:

 

MonCvONE is a full field projection perimeter entirely compatible with the Goldmann standard and modern perimetry standard.  It allows high resolution static and kinetic perimetry with automated and manual modes.  It is presently the only perimeter capable of TRUE BINOCULAR exams.

It is therefore the best option to test visual aptitudes for drivers and handicapped subjects.

Its video recording capability means that it is also suitable for the assessment of ptosis, the investigation of diplopia in the visual field and for recording the cardinal positions of gaze.

 

Moorfields Acuity Chart:

 

The Moorfields Acuity Chart (MAC) test includes two different, foldable letter charts (MAC 1 for the right eye and MAC 2 for the left eye).  The letters are composed of a black core with surrounding white borders and are presented on a grey background.  This leads to the appearance of the letters vanishing close to threshold, hence their description as ‘vanishing optotypes’. 

The charts are constructed based on the gold standard design of the Early Treatment Diabetic Retinopathy Study (ETDRS) charts.  These employ a logarithmic progression in letter size allowing for single letter scoring.  This has demonstrated more accurate visual acuity measurements with lower test retest variability.

Nidek Autorefractor (limited availability):

 ‌

The newly designed optical unit allows measurement of the minimum pupil diameter up to 2.0 mm and high-accuracy measurement.

Ocular Response Analyser (limited availability):

 ‌

Ocular Response Analyzer® (ORA) is the only tonometer that measures Corneal Hysteresis (CH), a superior predictor of glaucoma progression. Corneal Hysteresis is an indication of the biomechanical properties of the cornea differing from thickness or topography, which are geometrical attributes.

Oculus C-Quant:

‌ ‌

The C-Quant makes it possible to measure the amount of stray light in a human eye individually and reliably. The effect of increased stray light in the human eye can be compared to looking through a dirty windshield.

Oculus Oxymap:

The Oxymap T1 was developed to fit the Topcon TRC-50D fundus cameras (above). It is composed of a custom-made optical adapter and two high resolution digital cameras (1600 x 1200 square pixels) which produce quality images in a 50° field of view without sacrificing pixel resolution across the vessels.

Oculus Pentacam HR:

‌ ‌

The Pentacam is a combined device consisting of a slit illumination system and a Scheimpflug camera which rotates around the eye.

Optos Tx200 Wide-Field Retinal Imaging and Angiography (limited availability):

 ‌

Multiple wavelength imaging, including options for color, red-free, fluorescein angiography and autofluorescence. With simultaneous non-contact pole-to-periphery views of more than 80% or 200 degrees of the retina in a single capture.

Optos California P200DTX:

 ‌

The compact desktop device offers greater imaging functionality and has introduced a new imaging modality, indocyanine green angiography, used for imaging the choroidal vasculature.

Pelli-Robson Contrast Sensitivity Chart:

 

Contrast sensitivity measurement provides a realistic assessment of how well a patient can see large, faint objects.  The Pelli-Robson chart utilises letters of the same size but with reducing contrast to provide a quick means of assessing patient contrast sensitivity thresholds. For use at one metre.

Power Refractor 3:

PowerRef 3 provides dynamic measurements of accommodation in sphere, convergence and pupil size changes in scotopic, mesopic and photopic conditions.

Professional Retinoscope:

  The unique optical design provides the first truly bimodal Retinoscope with just a quick bulb change. A true streak or spot - no compromise.

RTX1 Adaptive Optics Retinal Camera:

 

The RTX1™ enables visualizing the living retina at a microscopic scale. While the optical resolution of every other retinal imaging technique is limited to 15-20 µm, the rtx1’s exceptional resolving power allows examination of details of a few microns in size. Images acquired with the RTX1 reveal previously invisible retinal structures, such as cones.

Slit Lamp (CS 990):

‌ ‌

The SL 990 series is characterized by a modern optic project and uses a multi_layered anti reflection treatment that ensures a more effective transmission of light, thus improving the optic resolution and contrast by 20%.

Smith-Kettlewell Institute Low Luminance (SKILL) Card:

 

An acuity test of reduced luminance and contrast.  The SKILL Card consists of two near acuity charts mounted back to back. One side has a chart with black letters on a dark gray background designed to simulate reduced contrast and luminance conditions. The other side has a high-contrast, black-on-white letter chart. The SKILL score is the acuity loss (number of letters) between the light and dark sides.

 

Specialist Ophthalmoscope:

  Precision optics, versatile features and practical ergonomics make it the number one choice for ophthalmic practitioners. Re-engineered optics give 30% more Xenon illumination, making it ideal to view through cloudy media and cataracts etc.

 Topcon TRC 50DX: Mydriatic Retinal Camera:

‌ ‌

 

 

The TRC-50DX series of mydriatic retinal cameras incorporate the latest digital-ready features to provide the most complete retinal image capture device today, including colour, red free, fluorescein angiography, fundus auto fluorescein and indocyanine green angiography.
