NIDEK Microperimeter

Microperimeter

It combines fundus imaging with visual field testing, allowing for the precise mapping of retinal sensitivity, establishing a correlation between retinal structures and visual functions. This approach can be advantageous for individuals with non-central or unsteady fixation caused by macular conditions such as age-related macular degeneration and Stargardt's disease.

Hand-held Assessment Devices

Various portable instruments can help optometrists conduct various examinations, including checking the refractive power of the eyes, the external eye health, measuring eye pressure, and taking retinal photographs. This enhances the testability of eye examinations for infants and children and facilitates examinations for individuals with mobility impairments or the elderly.

Senaptec Sensory Station

Senaptec provides assessments for sports vision and visual perception, along with interactive training programs designed to improve a range of visual processing and reaction skills, including dynamic vision, visual search, eye tracking, and eye-hand coordination. These programs may be beneficial for athletes to optimize their sports performance.

Virtual Reality Training

Virtual reality training is mainly used to improve amblyopia and binocular coordination problems in children and adults. By changing the contrast of the images seen by both eyes, strengthening high-contrast images for the weak eye, and preventing suppression by the dominant eye, it encourages both eyes to work together. The training software can also change the image position of each virtual reality viewer to project images onto the fovea of the strabismic eye, thereby improving binocular coordination.

Augmented Reality System

VTS4 – Hololens augmented reality system allows assessment and training of vergence and oculomotor problem. The integrated eye tracking system can monitor and analyze the movements of both eyes in real-time during assessments and training sessions.

Bragi

3D Printing Frame

This system leverages advanced 3D printing technology to create personalized eyeglasses tailored to the unique facial features and style preferences. With precise scanning, the system ensures optimal fitting and comfort.

Essilor Visioffice 3

Personalized Lens Measurement Device

The dispensing device can provide precise and personalized lens measurements. It uses 3D technology to capture detailed eye and facial data, ensuring accurate lens fitting and visual comfort. The device offers a comprehensive analysis of visual behavior and preferences, enhancing patients’ experience.

Essilor Wave Analyzer Medica 800

Aberrometer

This fully automated aberrometer can measure ocular aberrations, which may be useful in fitting specialty contact lenses and assessing the suitability of refractive surgeries.

Hess Screen

The Hess screen is utilized to evaluate ocular motility in cases of strabismus. This examination assists in identifying the degree and direction of limitations in eye movement, facilitating the diagnosis and treatment of a range of eye conditions affecting eye alignment and movement, including third, fourth, and sixth nerve palsies, thyroid eye disease, and orbital floor fractures.

Dry Eye Assessment

Dry eye diagnostic instruments can provide a comprehensive evaluation of dry eye conditions. This includes analyzing tear osmolarity, tear film stability, and lipid layer thickness, as well as meibomian gland imaging and Demodex microscopic examination. These devices aid in the detailed assessment and diagnosis of dry eye conditions, allowing for the recommendation of appropriate treatment methods.

Dry eye Management

After a thorough dry eye assessment, appropriate treatment will be recommended. There are different treatments designed to target specific subtypes of dry eye. These treatment principles include various approaches, such as Quantum Molecular Resonance technology to stimulate metabolism and promote gland regeneration, as well as the use of heat and vibrating massage to clear meibomian gland blockages and improve lipid secretion. These treatments can effectively improve both the signs and symptoms of dry eye.

NIDEK CEM 530

Specular Microscope

Specular microscope is used to examine the health of the cornea by measuring and calculating corneal thickness, endothelial cell count, density, average area, standard deviation, coefficient of variation, the areas with the most and least cells, and the percentage of hexagonal cells. These data help in screening and assessing corneal diseases, such as endothelial dystrophy, and in evaluating the health of the cornea when wearing contact lenses.

Electrophysiology

This is an electroretinogram (ERG) device, which measures the electrical activity of the retina (the light-sensitive cells at the back of your eye) in response to light. It is used for diagnosing and monitoring retinal diseases, including but not limited to retinitis pigmentosa, glaucoma, and maculopathy. This device can also provide visual evoked potential (VEP) measurement, which measures how the brain responds to light and the integrity of the visual pathway. It is useful in diagnosing vision problems and neurological conditions.

Vocational Colour Vision Assessment

These devices assess and diagnose colour vision deficiencies, evaluating how individuals perceive and distinguish colours, which is particularly important in professions like aviation. Individuals who failed the Ishihara test are required by The Hong Kong Civil Aviation Department to perform either the Optec 900 Test or the CAD Test. These devices help to ensure that pilots can interpret coloured signal lights accurately, especially in scenarios such as night flights or emergency situations.

By using specially designed vision charts and equipment, optometrists can create a relaxed environment to assess infants’ and toddlers’ vision and refractive errors.

Binocular Vision Assessment and Training

By utilizing visual training tools such as lenses, prisms, eye patches, red-green glasses and filters, the goal is to enhance the eyes' vergence and accommodation abilities while reducing the brain's suppression of the strabismic or amblyopic eye.
