[0002] Ophthalmic surgery is a type of surgery specifically performed for eye diseases, and is mainly divided into internal eye surgery and external eye surgery. Internal eye surgery requires high sterile conditions, and external eye surgery is currently the most common conventional surgery. Internal eye surgery has a simple division of anterior and posterior segments, including the lens, iris, glaucoma, etc., and the level of precision required for surgery is relatively high. During ophthalmic surgery, the patient cannot keep his eyes open by himself and needs the help of an eyelid opener. The eyelid opener, also known as a face opener, is an instrument used to open the patient's eyelids during eye surgery to facilitate surgery. It is conducive to expanding the surgical field and facilitating doctors to perform surgery. It is an indispensable medical auxiliary device in ophthalmic surgery.

[0003] Most existing eyelid stretching devices simply use clips to clamp and stretch the eyelids, which can easily cause certain damage to the eyelids, and are difficult to adjust and adapt to the eyelids of different people. In addition, during the process of stretching the eyelids, the stretching components have poor adaptability to the eyelids, the stability of the stretching process is poor, the risk of secondary medical treatment is high, and the "hard contact" between the stretching components and the eyelids can easily cause additional damage to the patient.
