Ocular Surface Diseases are disorders of the tear-film, lid-margin, conjunctiva and the epithelial layer of the cornea which can seriously affect the patient's visual quality and quality of life. As one of the most common Ocular Surface Diseases, Dry Eye has becomes a global health issue. It is estimated that at least 300 million people suffer Dry Eye in China. Factors including the excessive use of mobile phones or computers, environmental pollution, systemic diseases (diabetes, hyperthyroidism, rheumatic autoimmune disease, etc.) and others have led to an increasing incidence of Dry Eye. Symptoms of Dry Eye include discomfort or pain, redness, itching and blurry vision and in severe cases, blindness due to corneal epithelium defect, corneal ulcer and scarring. Allergy, infection and pterygium are other common causes for a patient's discomfort and visual impairment. Some rare ocular surface disorders such as pemphigus, symblepharon, tumour and Stevens-Johnson syndrome can result in the loss of vision and physical appearance.
