Background

Currently, most ophthalmic surgery is local anesthesia surgery, and the surgical site of various ophthalmic surgery is not located at the cornea, and if the operation is performed at other parts of the eye, protection of the cornea is ignored. Under normal physiological conditions, the corneal surface is covered with tear film to prevent corneal dryness. In the ophthalmic operation process, the eyelid is often spread by an eyelid speculum, so that the cornea of a patient is exposed to the air for a long time, the normal breaking time of the tear film is about 15 seconds, which is far shorter than the operation time, and the bare cornea is exposed to the air after the tear film is broken, so that the occurrence of the exposed keratitis is extremely easy to occur. Meanwhile, in the ophthalmic surgery, light irradiates eyes of a patient, discomfort caused by strong light irradiation easily enables the patient to unconsciously rotate eyeballs, and the risk of accidental injury of the eyeballs by surgical instruments is increased.

Meanwhile, various ophthalmic surgeries need to stop blood, and common hemostatic devices used in ophthalmic surgeries are medical cotton swabs, medical cotton balls and medical gauze. Most ophthalmic operations are micromanipulations, medical swabs can be enlarged under a microscope, and the ophthalmic forceps are used for directly clamping the swabs to stop bleeding obviously and inconvenient. If the operation is performed by using the conventional medical cotton ball, the conventional medical cotton ball is far larger than an eyeball, so that the hemostatic operation is inaccurate, a doctor cannot determine whether to accurately stop bleeding or not, and in addition, the medical cotton ball is large in volume, too many parts which do not need to be hemostatic are easily shielded, the operation of the doctor is greatly interfered, and the difficulty is caused for smooth operation. In practical ophthalmic operation, doctors often intercept small parts of medical cotton balls and knead the medical cotton balls into various shapes for hemostasis in operation, and the operation has the following problems: firstly, the modified cotton balls have different shapes, and most of the cotton balls do not conform to the anatomical morphology and line trend of tissues at a plurality of positions of the ocular surface; secondly, the quantity of the 'cotton balls' intercepted is not fixed, if the quantity of the 'cotton balls' which are not accurately recorded before an operation is finished, if the 'cotton balls' manufactured before the operation are forgotten after the operation is finished, the difficulty is greatly increased for counting after the operation, and the key is that the condition that the cotton balls are left on eyes of a patient is easily caused, so that unnecessary injury is caused to the patient. Therefore, the defect of the hemostatic operation by adopting the conventional medical gauze is obvious.
