However, before the treatment of dry eye disease requires a clear examination, the examination of dry eye disease is more complex, currently there are several commonly used methods, such as tear secretion test, tear film rupture time, biopsy and blot cytology, fluorescein staining, tiger red staining, tear lysozyme content, tear osmolarity, lactoferrin and other tests, only after a clear diagnosis of the specific cause, can be targeted treatment. The starting point of current treatment is mainly the following, such as elimination of causative factors (reduction of prolonged eye use), replacement therapy of tear components (artificial tears such as methylcellulose drops), prolongation of tear residence time on the eye surface (silicone eye shields), and others (avoidance of drugs that reduce tear secretion). To sum up, the best treatment for dry eyes still needs to be based on the patient’s specific situation and professional treatment to develop a suitable plan to achieve effective treatment.
