Understanding Dry Eye
Caring for your tear film and understanding dry eye
What is my tear film?
The tear film protects and nourishes the front of the eye, the cornea. An irregular tear film has the potential to cause anything from mild discomfort to severe irritation and can impact your quality of life and vision.
What is dry eye?
When the tear film does not function correctly, and not enough tears are produced, the eye dries out. Dry eye is a common condition, causes include:
- Air-conditioned or heated environments
- Windy, cold, dry or dusty conditions
- Some medications
- Certain medical conditions; such as blepharitis
- Computer screen use
- Eye surgery
What are the symptoms of dry eye?
- Gritty eyes
- Feeling like something is in your eyes
- Stinging or burning eyes
- Heavy eyelids
- Blurred vision
- Watery eyes (if your eyes water a lot, you may dilute the oily layer of your eyes, causing them to dry out)
How to treat dry eye?
Eye drops help to alleviate he feeling of dry eye by lubricating the eye's surface (the cornea).
AEON eye drops contain sodium hyaluronate (HA), the eye's natural lubricate that hydrates and lubricates the eye's surface to offer relief from dry eye symptoms.
Dry eye before and after surgery
Before eye surgery
It is important to prepare your eyes for any eye surgery. Your eye specialist may suggest using eye drops to treat dry eye in the lead up to your surgery. This helps your eye specialist accurately take measurements from your eye and gives the best chance of achieving the vision you desire.
After eye surgery
It is perfectly normal to experience dry eye after eye surgery, in fact over 75% of people that undergo cataract surgery suffer from dry eye and it is even more common after laser surgery.1Surgery to the eye’s surface can temporarily damage the nerves that are important in regulating tears. You may experience a gritty sensation after surgery which is associated with dry eye and it can last a few months whilst the nerves regenerate.
