This is Dr. Hofbauer information on the treatment of dry eye.
An adequate tear layer is necessary for the health and comfort of your eyes. The tears lubricate and nourish the surface of the eye, and help prevent infection.
The tear film on your eye is actually made up of three layers. The outer layer is oil or lipid based to slow evaporation. The middle layer consists of salt, water, and protein. The inner mucin layer keeps the tears spread evenly instead of beading up. All of these components must be present in the correct proportion.
When the eye does not produce adequate tears, it becomes irritated, itchy, and burning. This irritation can then trigger tearing. That is why a person whose eyes are tearing can still be considered to have "dry eyes."
Artificial Tears
The most common treatment for dry eyes is the use of artificial tears. These drops can be used as often as needed to provide comfort.
Some brands of artificial tears include Refresh PlusÒ, GentealÒ, and Tears Naturale IIÒ.
However, if used continuously one may develop an allergy to the preservatives in the drops. People with chronic dry eyes are recommended to use artificial tears without preservatives. These drops will have "Preservative Free" or "PF" on the label.
Gels
If the artificial tears help only briefly, Dr. Hofbauer may recommend a thicker solution such as Bion TearsÒ or CelluviscÒ. These are artificial tears mixed with methylcellulose. This will provide longer-lasting relief, but may temporarily blur your vision.
Ointment
To keep your eyes lubricated throughout the night, Dr. Hofbauer may recommend an ointment such as Refresh PMÒ. This is applied just before going to bed.
Punctal plugs
There is another technique to keep more tears in the eyes, by plugging up the tube that drains the tears away. The punctum is a tiny opening in the eyelid, that empties into your nose and throat. A soft insert can block this opening. Dr. Hofbauer can do this procedure in the office.
In Addition....
Drinking plenty of water keeps your body hydrated, and may help with tear production. A humidifyer in your house will slow down the evaporation of your tears. Wrap-around eyeglasses block the wind and may hold more moisture in front of your eyes.
Important!
This information is to be used only after the diagnosis of dry eyes has been made by your doctor, and is not intended to take the place of a medical exam.
