Diagnostics & Technology



Zeiss Visucam fundus camera – It is a digital camera from Zeiss that provides photographs of the inner surface of the eye including fundus, macula, optic disc and retina. The fundus cameras are used for diagnosing the condition, monitoring the progression of a disease, and in screening procedures. Zeiss Visucam Fundus Camera delivers two-field angles the standard 45° and the smaller 25° field for excellent photos of the optic disc and macula. It is valuable in the diagnosis of glaucoma, diabetic retinopathy and other retinal diseases. It provides both red colour and red free colour taking modes; red free colour mode is used to visualize the blood vessels on the retina after angiography.





Cirrus OCT – It is one of the most advanced optical coherence tomography (OCT) system used to view the retina, back layer of the eye, including the optic nerve and the macula. It is manufactured by Carl Zeiss Meditec, an integrated medical technology company. This allows for early detection of retinal disease accurately and objectively, designing of treatment protocol and also optimises evaluation of pre- and post- therapy changes. This new high-performance OCT instrument delivers exquisite high-definition images of ocular structures. It is used for the management of glaucoma and retinal disease, retina assessment for cataract surgery, and anterior segment imaging for corneal disease. The Cirrus OCT is organized with the most advanced applications, such as advanced RPE (retinal pigment epithelial) analysis and ganglion cell analysis, retinal tracking, and macular thickness and change analysis. The new Cirrus OCT allows more practitioners to offer patients a high level of care.


humphrey-fieldHumphrey Visual Field Analyzer – It is the accepted standard of care in glaucoma diagnosis and management. This is the premier automated visual field perimeter to measure visual field of the eye. Visual field test measures the capacity of your eye in ‘side vision’. Visual field may be impaired in the diagnosis of conditions which affect the visual field such as glaucoma, macular degeneration, retinal detachment, diabetic retinopathy, certain neurological conditions and other conditions affecting the optic nerve of the eye.




FDT Matrix Visual Field Analyzer –








atlas-9000Atlas Cornea Topographer – It is a latest device used to create topographic map of the cornea which is similar to a contour map of the surface of the land. Atlas Cornea Topographer combines the highly sophisticated software programs with most advanced imaging and analysis technology. It is used in planning and evaluation of LASIK surgery and for the diagnosis of keratoconus. It is also used to assess the appropriate fit of the contact lenses especially for people suffering from keratoconus, in diagnosis and management of corneal conditions and procedures such as corneal transplants, corneal opacities, corneal deformities, post-operative cataract extraction with acquired astigmatism.



Lumenis Selecta Duet SLT and YAG laser – represents one of the industry’s most advanced anteriorsegment laser, combining the advantages of YAG photodisruption capabilities along with the innovative Selective Laser Trabeculoplasty (SLT) technology, which was developed and brought to market by Lumenis.

The system’s fully integrated design, enhanced optics and advanced laser cavity make the Duet one of the best performing laser products in its segment



DIOPSYS Electroretinography (ERG) – is a direct measure of retinal activity, particularly the macula and ganglion cells. ERG is a test that provides data intended to aid in detection of cellular dysfunction and diagnosis of visual problems, and may allow eye doctors to preempt visual problems before they occur. Many diseases like Age-related Macular Degeneration (AMD), Diabetic Retinopathy, Glaucoma, and maculopathy of plaquenil-related etiology can be effectively managed with early detection, which is exactly what this tool provides.





Diopsys Visual Evoked Potential (VEP) – measures the nervous impulses traveling from the retina to the visual cortex. Light that enters the eye ultimately falls on the retina, a photosensitive nervous tissue at the back of the eye. From there, a message is conducted through nervous tissue (e.g. the optic nerve) until it falls on the brain’s occipital lobe, which is actually located on posterior portion of the brain. On this lobe lies the visual cortex, where information that reaches the brain is cognized as vision. VEP provides specific information about the electrical impulses conducted through the nervous tissue, including metrics like impulse strength and speed. This can provide valuable insight to potential visual problems that was previously unavailable to eye care specialists.
