What is Dry Eye?
Dry eye is a common condition that occurs when the eyes are insufficiently moisturized, leading to itching, redness and pain from dry spots on the surface of the eye. The eyes may become dry and irritated because of many different reasons such as your tear ducts not producing enough tears, corneal exposure, or rapid evaporation of tears. At your initial consultation at either our Westborough or Salem offices, Dr. Jean Keamy will evaluate your eyes and assess the proper cause of your dry eyes. She will then follow up with individualized treatment plan to help alleviate your discomfort.
Causes of Dry Eye
Many people usually start to experience dry-eye symptoms as they age. Dry Eye can also result from medical conditions, injuries or certain medications. Dry eyes tend to affect women more than men because of the hormonal changes that take place during pregnancy and menopause. Oral contraceptives can also affect the consistency of tears. Other causes of dry eye include the following:
- Antihistamines, decongestants and blood-pressure medications
- Rheumatoid arthritis, diabetes, Sj®gren’s syndrome and thyroid disease
- Environmental conditions such as smoke, wind or excessive sun
- Long-term contact lens use
- Eye injury
- Eye or eyelid surgery
- Inflammation of the eye (conjunctivitis or keratitis)
Symptoms Of Dry Eye
Patients with this condition often experience irritating symptoms and which may result in more serious damage to the vision if the condition is left untreated. Common symptoms include:
- Eye discomfort
- Feeling of something in eye
- Itchy eyes
- Blurred vision
- Crusty Eyelids
It is important for patients with this condition to take special care of their eyes in order to alleviate symptoms and prevent complications. Dr. Keamy will diagnose dry eye after a thorough evaluation of your eyes and tear production with a Schirmer tear test.
Types of Dry Eyes
There are two types of dry eyes. One type can be due to pore reduction of the watering component. With the decreased secretion of tears or aqueous solution to coat to the eye, patients often feel they are always dry, causing a great deal of discomfort.The other type of dry eye can be described as evaporative dry eye. Approximately 86% of patients with dry eyes suffer from this specific type. The oil glands located along the eyelid are clogged, causing evaporative eyes. The oils secreted from the Meiobomian Gland form a protective layer to prevent the tears from evaporating. With the decrease in the oil layer, the aqueous layer experiences rapid evaporation, causing dry eyes.

Treatments Options For Dry Eye
Dry eye can make normal activities such as driving, watching television, reading or using a computer very uncomfortable. If left untreated, dry eye may cause sufferers to be unable to wear contact lenses and can lead to eye surface damage and vision problems over time.
At Keamy Eye & Laser Centre, we are able to provide many different treatment option to help alleviate dry eye symptoms. Our treatment options include the following:
There are many dry eye patients that suffer from blepharitis. This chronic inflammation is due to an overgrowth of normal bacteria living along the eyelid and the base of the eyelashes. This overgrowth causes crusting along the eyelid, or a sticky biofilm that harbors bacterial exotoxins. Throughout time the biofilm has a direct impact on the function of the tear glands, causing dry eyes. BlephyEx is an in office procedure performed to treat blepharitis by eliminating the biofilm and bacterial toxins. By eliminating the biofilm layer, this improves the overall health of the eyelid and allows proper function of the tear glands.
