What are the sequelae of orbital surgery

Orbital surgery is prone to cause some sequelae, such as dry eyes or severe keratitis, which can cause vision loss. Therefore, after these operations, you must pay attention to health care to prevent these complications.

1. Types of sequelae

First, dry eye syndrome (this is a very difficult eye disease, and the current treatment is only symptomatic

Myopia surgery

Myopia surgery

cannot be fundamentally resolved);

Second, [complication of severe keratitis] (such as the need for corneal transplantation when viral keratitis is at its worst);

Third [Visual regression] (regress to the original state or slightly better);

Fourth, [corneal flap rupture caused by accidental collision after surgery] is complicated by a series of serious complications;

Fifth [Keratoconus] (can only be treated with corneal transplantation. The best visual acuity after the operation can reach 1.0. The quality of visual acuity mainly depends on factors such as suturing skills and whether there is rejection reaction).

2. Preventive measures

1. Strictly grasp the indications. As we all know, no matter what surgery is done, there is an indication problem. Not all myopia can be treated surgically. Some do not need or are not suitable for myopia surgery, such as fundus lesions, vitreous opacities, severe irregular astigmatism, etc. Myopia surgery will not only fail to increase vision, but will bring many complications.

2. Good nursing conditions and quiet and comfortable ward facilities are also indispensable for preventing complications, such as bruising the operated eye due to improper nursing, falling out of bed while bandaging both eyes after surgery, or contamination of the wound during dressing changes, leading to infection.

3. The patient's full mental preparation and active cooperation with treatment during and after the operation are another important link to ensure the success of the operation. Complications may occur if one is not mentally prepared enough, is overly nervous during the operation, or moves the head.

4. The surgeon must have extensive experience in microsurgery, have undergone rigorous microsurgery training, be familiar with the microsurgical instruments used in surgery, and be familiar with the conditions of the cornea and eyeball with various types of refractive errors. He must also be able to cope with various unexpected situations during surgery, properly handle various problems, and prevent and reduce the occurrence of complications.

5. Effective retrobulbar anesthesia is an important part of ensuring the success of the operation. Inadequate anesthesia, intraoperative patient pain or orbicularis oculi muscle contraction, eye movement, etc. may cause unexpected complications.
