Shack-Hartmann wavefront maps point out lower-order and higher-order aberrations.

Diagnose, Evaluate, Monitor

Displays a colour image of the eye and uses the Efron grading scale to grade the level of redness,
the overall quality of the eye and lids. This feature focuses on the meibomian glands area to screen
Meibomian Gland Dysfunction (MGD).

Using the manual zoom of the colour camera, youcan measure the height of the tear meniscus to
complete the test.

Follows the recommendations from the Tear Film& Ocular Surface Society (TFOS) and Dry Eye
Workshop (DEWS II) reports.Placido rings analysis and anterior eye camera and displays colour image of Meibomian glands.

Diabetic retinopathy can lead to other serious eye conditions:
Over time, about half of patients with diabetic retinopathy will develop Diabetic macular edemea
(DME). DME happens when blood vessels in the retina leak fluid, causing swelling in the macula
(a part of the retina). If a patient has DME, their vision will become blurry because of the extra
fluid in their macula.
An eye care professional will look at the retina for early signs of the disease, such as:
• Leaking blood vessels,
• Retinal swelling, such as macular edema,
• Pale, fatty deposits on the retina (exudates) - signs of leaking blood vessels,
• Damaged nerve tissue (neuropathy),
• Any changes in the blood vessels.

Age-related Macular Degeneration is caused by the deterioration of the central
portion of the retina, the inside back layer of the eye that records the images we see and sends
them, via the optic nerve, from the eye to the brain.
The retina’s central portion, known as the macula, is responsible for focusing central vision in the
eye, and it controls our ability to read, drive a car, recognize faces or colors, and see objects in fine
detail.
Visualizing and tracking changes in retinal layers is important in managing patient visual health.
