Dry eye is a common ocular surface disease caused by old age, excessive eye use, systemic diseases and medications (mainly eye drops). Patients show symptoms such as dry eyes, redness, foreign body sensation, itchy eyes, eye fatigue and blurred vision, which can lead to vision loss or even blindness in severe cases. If patients suffer from dry eye disease and abuse eye drops, not only will they fail to achieve effective treatment, but they will also aggravate the disease and even cause serious complications. Patients with dry eye disease must be individualized after detailed examination by a specialist, such as mild dry eye disease patients only need to treat the cause and local point artificial tears treatment; while patients with moderate and severe dry eye disease, such as the use of drugs only, not only the efficacy is poor, frequent daily point eye more trouble, and artificial tears are often more expensive, thus long-term use of drugs will bring a great economic burden to patients. Therefore, at present, the more ideal treatment method for patients with dry eye disease is to implement tear suppository treatment, because, this method is simple and non-invasive and painless, not only to stop the loss of the eye surface of their own tears and artificial tears, but also to extend the residence time of tears in the eye surface, which can make patients stop using or reduce the number of artificial tears, and remove the plug if necessary. Of course, individual patients with dry eye need anti-inflammatory or even surgical treatment.
