CATARACT STATION
Cataract is the clouding of the normally clear lens inside the eye leading to blurring of vision. Naturally, it is part of aging and slowly progressive thru time. At the onset, frequent change of prescription glasses and increased lighting are only needed. Impairment of daily routine functioning can be an indication for the removal of cataracts, thus, a cataract surgery is needed. Comprehensive evaluation of the eye is necessary to evaluate all the parameters needed to produce good visual outcomes for these patients.

Corneal Topography(Topcon) produces a computerized surface image of the cornea giving a descriptive mapping of the surface curvature
The Topcon CA-800 Corneal Analyzer is an easy-to-use, comprehensive corneal topography solution allowing for the complete evaluation of the anterior corneal surface. In addition to elevation mapping of the corneal surface, the CA-800 provides robust software features, allowing for a total analysis of the patient’s corneal surface.
The Topcon CA-800 Corneal Analyzer is a standalone unit capable of sending reports directly to a printer or to a shared network folder via LAN connectivity. However if remote analysis is desired the CA-800 is compatible with i-MAP reviewing software for your PC. The CA-800 is controlled by a 10-inch capacitive touch panel monitor and combined with familiar joystick operation acquisition and evaluation of the cornea is fast and easy. Additional features include pupillometry, fluorescein imaging, meibomian gland imaging, contact lens fitting software, white to white measurement, Zernike analysis and tear meniscus analysis.
Tear Film analysis (I-pen Osmolarity System) simple, quick, accurate measurement of the tear osmolarity. In conjunction with results of the Corneal Topography, patients with Dry Eye Syndrome can be detected and managed accordingly prior to the surgery.
I-pen Osmolarity System
Simple, quick, accurate measurement of the tear osmolarity. In conjunction with results of the Corneal Topography, patients with Dry Eye Syndrome can be detected and managed accordingly prior to the surgery.
I-PEN is the world’s first, hand-held in-vivo device for measuring elevated tear film osmolarity levels associated with mild, moderate and severe Dry Eye Disease. The I-PEN, an in-practice dry eye screening device, provides rapid and reliable tear osmolarity levels for patient presenting with dry eye symptoms as well as pre- and post-surgical cases.
• Quantitative measurement – easy to record and follow over time
• Rapid results – less than 5 seconds
• Handheld, light & simple to use
• Affordable point-of-care testing
Corneal Endothelial Specular Microscopy
The Topcon specular microscope, SP-1P introduces a modern ergonomic design and innovative features that simplifies its use and increases its efficiency.
A large 10.4 inch rotatable touch panel monitor eliminates the need for a control lever, and can be turned to various angles, for better interaction with the patient. By simply tapping on the center of the patient’ s pupil displayed on the monitor, this specular microscope automatically centers, focuses and acquires the endothelial cell image. The SP-1P, specular microscope, workflow takes just a few seconds, requiring minimum training. The space saving features combined with its ease of use makes the SP-1P, specular microscope, the instrument for a new generation in eye care.
RETINA STATION
Retina is a thin light-sensitive lining inside the back of the eye . It receives light as it is focused thru the lens. This will then be transmitted as nerve signals to the brain thru optic nerve, enabling the eye to see. Screening of the retina is vital in patients with Diabetes, Hypertension, Tuberculosis, Blood dyscrasias and with history of prolonged intake of certain drugs.

ZEISS VISUCAM fundus cameras, with a 24-megapixel sensor and revolutionary ZEISS optics, produce brilliant, ultra-high resolution, detail-rich images to effectively aid in diagnosing and monitoring a broad range of eye diseases – from glaucoma and diabetic retinopathy to macular degeneration (AMD).
Digital Fluorescein Angiography(FA) (Zeiss Visucam) Fluorescein dye highlights the blood flow of retina thru time so it can be photographed. These serial photographs defines the disrupted areas of blood flow of the retina and lesions, producing a mapping of the retina that is important in planning for treatments.

Optical Coherence Tomography (OCT) of the macula( Zeiss Cirrus/Heidelberg OCT spectral domain technology) describes the different layers of the retina at the macula(central area of the retina) using light waves.
CIRRUS HD-OCT 5000 is configured with the highest resolution visualization capabilities and sophisticated clinical applications such as Advanced RPE analysis to track retinal pigment epithelial integrity and Ganglion Cell Analysis to assess glaucomatous loss in the macula that may not be evident in the peripapillary region. The new FastTrac™ retinal tracking reduces eye motion artifacts without sacrificing patient throughput with a proprietary scan acquisition strategy, high speed 20 Hz LSO camera, and single-pass alignment scanning. This feature enables the highest resolution B-Scans to be captured in identical locations from visit to visit providing precise assessment of change in targeted pathologies.
B-scan Ultrasonography ( Sonomed EZ scan AB 5500/ Vumax HD) provides two dimensional cross-sectional view of the eye and surrounding tissues.
The E-Z Scan AB5500+ offers a portable, digital, combination A-scan and B-scan, with easy-to-use touch screen operation, high resolution, extreme accuracy, repeatable measurements and trusted Sonomed Escalon reliability.
The E-Z Scan A-Scan offers built-in immersion capabilities and up to eight IOL formulas, including two post-refractive formulas. Axial length, ACD, and lens thickness are provided for each scan. Group up to five scans with average axial length and standard deviation automatically calculated. Easily review each scan, delete outlying scans, and add new scans, as desired. Customizable tissue velocities of each structure and highly-developed automatic scan recognition algorithms ensure accurate and repeatable measures. Built-in calibration check ensures continued accuracy of system.
The E-Z Scan B-Scan provides excellent resolution with a full set of features including display of A-scan trace across a selectable vector, zoom and pan capabilities, multiple color and grayscale display modes, measurement functions, annotation, and more. The real-time B-scan display, adjustable gain and TVG controls, and enhanced “high-resolution” mode which produces a scan with 256 line vectors facilitate optimal diagnostic viewing.
Color Vision Testing( Ishihara test / Farnsworth Test) Color blindness screening is important in the workplace.
The Farnsworth-Munsell 100 hue test is one of the most famous color vision tests available. It belongs to the group of hue discrimination, also called arrangement tests. Another famous test in this group is the Farnsworth D15 arrangement test.
The aim of the test is to order the shown color plates in the correct order—any misplacement can point to some sort of color vision deficiency. You’ll find the detailed instructions in the test itself. So relax, take you some time and Start the Farnsworth-Munsell 100 hue color vision test now.
GLAUCOMA STATION
Glaucoma is a condition wherein the pressure inside the eye can cause damage to the optic nerve( main nerve of the eye that is connected to the brain) leading to vision loss. Most of the patients with glaucoma has no early symptoms or pain.
