Prosthetic Eye dryness, Why, What and how.
Artificial Eye users may experience Prosthetic Eye Dryness while using their prosthesis. To learn more on why this dryness occur, I divided this post in 4 segments.
What are Tears?
Tears are watery substances secreted by our Lacrimal Gland. Aside from preventing our Eyes from getting dry, it also serves as a cleaning agent to protect our eyes from infectious agents and It plays a part in the osmotic regulation.
What makes up the Tears?
Our tears are made up 3 distinct layers.
- it coats the cornea and provides a hydrophilic layer. It's what makes the tears film evenly distributed all over the cornea.
There are three reasons how a person, regardless if they are a Prosthetic Eye user or not, can experience Dryness.
First, There could be a decrease in the production of Tears
There are many lubricants that can be used to alleviate Prosthetic Eye dryness. The difference between an Artificial Eye and a Natural Human Eye is that a Human Eye doesn’t usually need a more viscous substance, unless they have severe dry eye.
As for an Artificial Eye, a more viscous substance is recommended to bring back the comfort of wearing the Prosthetic Eye.
Some Examples that could serve as a lubricant:
Artificial Eye Drops
Note: I recommend a more viscous Artificial tear especially to patients whose eyelids are partially opened and/or doesn't close close entirely when asleep or when blinking.
