Dry Eye

Dry Eye Treatment

Serving Eye Patients in Johannesburg, Africa

Patients with dry eye either do not produce enough tears or lack good quality tears to properly nourish the eye. Tears are essential to maintaining healthy eyes because they serve as lubrication, help prevent infections, and wash out harmful debris. Dry eye is not only uncomfortable; it can also damage the surface of the eye and cause vision problems if left untreated.

Tears consist of three layers:

  1. Oily layer – reduces evaporation of tears
  2. Watery layer – cleanses the eye
  3. Mucus layer – Allows the watery layer to spread out smoothly and moistens the eye

Patients who suffer from dry eye often have a problem creating enough of one or more of these layers. Dry eye can actually cause the over production of tears as well. If a person has low-quality tears, the eye is not moistened properly and can become irritated. This can cause excess tearing or “watery eyes.”


Dr. Guglielmetti can prescribe a specific treatment to correct your unique dry eye condition. Mild dry eye can usually be treated with tear replacement eye drops that can be used as often as several times an hour. Some patients even find relief by taking omega-3 fatty acids to help supplement their tear production. Other patients with more severe cases may need to be prescribed medications or undergo eye surgery. Tear ducts can be temporarily or permanently closed to conserve more of your own tears, especially if the cause of dry eye is low production of tears.


Chronic dry eye can be diagnosed during a general eye exam with special attention to the quality and amount of tears the patient produces. Dr. Guglielmetti can perform tests to determine the cause and severity of your dry eye. Possible causes of dry eye include aging, certain medications, climate, and heredity. It can also be a side effect of laser eye surgeries such as LASIK.

Dr. Guglielmetti also performs cataract surgery and is a top glaucoma treatment provider in Johannesburg, South Africa. He specializes in lasik eye surgery and other surgical vision procedures.
