Treatment:
Before starting treatment for dry eyes, the eye-care specialist will first diagnose the cause of the problem and then prescribe appropriate treatment, depending upon the cause. Artificial tear drops are amongst the most basic treatment for mild dryness. However, for severe and chronic conditions, the doctor may prescribe medicated eye drops like Restasis to relieve dryness and inflammation. Restasis is an immunosuppressive agent and works by increasing tear production in the eyes. However, these are prescription drops and should only be used after consulting an eye specialist.
The eyes are a very sensitive and delicate organ. Ignoring the symptoms or delaying treatment can lead to further complications. These simple self-care measures will help prevent dry eyes, but are not meant to substitute for the treatment prescribed by the doctor.
