Background technique

Eyes are particularly important to people's lives in daily life. Due to the frequent use of eyes, various problems have arisen in the eyes. In the current treatment of eyes, eye drops are often used as adjuvant therapy. Most of the methods used for eye drops are to open the eyelids by hand. Due to postoperative eye pain and conditioned reflexes, it is difficult to open the eyes and instill the eye drops smoothly. Instilling into the eye causes waste and requires a second drop of medicine, which is not conducive to the recovery of the patient's eye after surgery; and it is difficult to see the drop of the eye drop when the eye drop is instilled, and it is difficult to judge when the eye drop falls to open the eyelids. There is a short waiting time during the drop of the eye drops. When the eye drops are instilled, the patient’s lack of psychological preparation is abrupt, which makes the instillation of the eye drops not smooth enough.

To sum up, there are the following problems in the current application of eye drops: it is difficult to open the eye after surgery and instill the eye drops smoothly, and it is easy to blink during the instillation, so that the drops cannot be instilled into the eyes, causing waste and requiring a second drop. It is not good for the eye recovery of patients after surgery; and it is difficult to see the drop of the eye drops during eye drops, and it is difficult to judge when the eye drops fall to open the eyelids; the use of both hands with eye drops is not sterile Operation requirements, easy to cause eye infection.
