the Ocular Surface, Contact Lenses and Dry Eye Disease
The Ocular Surface is a complex and delicate arrangement of organs
at the front of the eyeball
that provides a moist environment
in order to perform the first steps of the Vision Process . . .
… the prototypic disease of the ocular surface
that occurs due to a loss of the essential moisture
is the most frequent diagnosis in ophthalmology
Tears are the Vehicle for the essential Moisture at the Ocular Surface.
Tears are produced by the Ocular Glands
- mainly the Lacrimal Gland but also others . . .
Contact lenses are a fantastic medical device.
The tempting idea of correcting refraction directly on the Ocular Surface
has a long history . . .
Tear Film Lipids are of utmost Importance
for the function of the Tear Film and thus
for the Ocular Surface as a whole.
The Meibomian Glands inside the eye lids
produce lipids that form an Oil at body temperature .
Meibomian Gland Dysfunction (MGD)
is the most frequent alteration of the lipid producing glands
inside the eyelids, and MGD is the main causative factor for Dry Eye Disease . . . .
In dry eye disease, there is typically a lack of tear film
- either in quantity or in quality. -

for ocular surface health and
for the onset and progression of Ocular Surface Disease,
in particular Dry Eye Disease . . .
... gives a short overview
about the function of the ocular surface and
the onset of Dry Eye Disease
- ideal for Your start into the topic . . .
