眼科手术时，保持眼表对无菌是很难的，而眼科手术一旦感染，带给患者的后果是相当严重的。

During ophthalmic surgery, it is difficult to keep the ocular surface absolutely sterile, and once ophthalmic surgery is infected, the consequences to patients are quite serious.

所以要特别注意可能引起感染的潜在因素，如泪囊炎、结膜炎、睑缘炎、全身状态、卫生情况等。

Therefore, we should pay special attention to the potential factors that may cause infection, such as dacryocystitis, conjunctivitis, blepharitis, general state, hygiene, etc.

对于术者来讲，除了精湛的手术技术，严格的无菌操作是非常重要的。

For the operator, in addition to exquisite surgical techniques, strict aseptic operation is very important.

其中，手术贴膜是手术开始的一个关键步骤。

Among them, surgical film is a key step in the beginning of surgery.

贴膜时用棉签将睑缘周围的泪液擦干，以便贴膜更好的贴伏，不要用手指直接接触术野；

When applying the film, wipe the tears around the eyelid margin with a cotton swab so that the film can be applied better. Do not directly contact the operation field with your fingers;

塑料膜要围绕眼区牢固的与眼睑包括睫毛及周围皮肤紧密粘着，避免液体进入贴膜下，减少术野污染机会；

The plastic film should firmly adhere to the eyelid, including eyelashes and surrounding skin around the eye area to avoid liquid entering under the film and reduce the chance of contamination of the operation field;

开睑器开睑时应将贴膜包饶睑缘和睫毛，避免睑板腺分泌物进入结膜囊；

When the eyelid opener is used to open the eyelid, the film shall be wrapped around the eyelid margin and eyelashes to avoid the secretion of meibomian gland from entering the conjunctival sac;

铺巾时动作轻柔，避免空气中棉絮、微粒飞扬；

When laying the towel, move gently to avoid the flying of cotton wadding and particles in the air;

铺巾后要留给患者足够的呼吸空间，必要时吸氧；

After laying the towel, leave enough breathing space for the patient and take oxygen if necessary;

无菌一次性使用自带贴膜手术巾具有使用方便、无棉絮、不需人工清洗、灭菌等优点，可推广使用。

Aseptic disposable surgical towel with film has the advantages of convenient use, no cotton wadding, no manual cleaning and sterilization, and can be popularized.
