Restasis, whose generic name is Cyclosporine, is an FDA-approved prescription medication used to treat chronic dry eye disease (keratoconjunctivitis sicca). The condition occurs when the eyes fail to produce sufficient tears, leading to discomfort, redness, and a gritty sensation. Restasis is available in the form of eye drops and is typically prescribed by ophthalmologists.

Restasis works in a unique and fascinating way to combat chronic dry eyes. It contains a key active ingredient called cyclosporine, which is an immunosuppressive agent. The primary mechanism of Restasis involves suppressing the immune system response in the eyes. This action helps to reduce inflammation and allows the tear-producing glands (lacrimal glands) to function more effectively.

When someone uses Restasis, the cyclosporine penetrates the ocular tissues and modulates the activity of specific T-cells, which are part of the immune system. By inhibiting the T-cells, the inflammation in the lacrimal glands diminishes, promoting tear production and restoring the tear film’s natural balance. As a result, the symptoms of dry eyes gradually alleviate, providing much-needed relief to the affected individuals.

Chronic Dry Eye Disease (Keratoconjunctivitis Sicca)

Chronic dry eye disease, also known as dry eye syndrome or keratoconjunctivitis sicca, is a condition that affects the tear film and ocular surface. The tear film plays a crucial role in maintaining the health and clarity of the eye’s surface, while also protecting it against infections. When this film is compromised, it can lead to a range of uncomfortable symptoms.

Understanding the root causes of chronic dry eye disease is essential for effective management and treatment. Several factors can contribute to the development of this condition, including aging, environmental factors, medical conditions, medications, prolonged screen time, and hormonal changes.
