Pterygium is a common eye disease. The main features of the surface of the eye is a new biological proliferation of the head, the head can invade the cornea, and even cover the pupil, a serious impact on vision. The main treatment of pterygium is surgical resection. The operation is to remove the cornea and sclera surface with a scalpel, in order to reduce postoperative recurrence, often need to do autologous conjunctival flap transposition.

The risk of pterygium surgery is the largest cut through the corneal or scleral cause eyeball rupture, and injury of medial rectus cause postoperative diplopia, strabismus. This is often a serious complication in patients with eyeball because touch to.

How can we minimize the serious complications? Generally speaking, there are eye doctor qualification of the operation are basically can control their own hand strength. The main risk factors are patients. Many patients can not control the movement of the eye, the eye will be involuntarily rotation. During the surgery, doctors asked patients to look right, to a point on the right of patients, but also keep the eye on the right of this point. The patient is often seen on the right eye, once again looking straight ahead. This rotation is sometimes very fierce. Because the surgeon's scalpel may be operating on the corneal surface, there is a chance of complications, damage to the cornea or sclera. If the patients' eye surgery can slow to specify the range of physicians and maintain fixed to a few minutes, the operation view of surgeons will be relatively stable, can more thorough resection of pterygium and ocular surface injury of cornea and sclera and normal tissue.

My habit is to communicate well with patients before the operation, so that the patient according to the following requirements to do eye exercises.

Let the patient lie down on the bed, hands on both sides of the body, head straight, and the ceiling in parallel, not looked not bow, but not turn. Throughout the exercise, the body and head position to remain unchanged. Keep the head, eyes turning right, right on a fixed point for 5-10 minutes, midway can blink, but the eye can not rotate, but can not turn head. The eye moves slowly, not too fast. Practice a few times can meet the above requirements, can be put on the right side of the fixation point removed, continue to practice. In other words, even if you can not see anything, you can also maintain the eye to maintain a fixed position does not rotate. That's all right. Because the operation in order to protect the cornea, often in the surface of the cornea with a thin layer of wet cotton film, the patient may not see anything. Which direction should we practice? Usually, the surface of the eyeball is close to the nose. Then the right eye of the right wing to be trained to see, and the left eye to practice to the left. No matter what eyes, we must practice to look down (pointing to the direction of the foot), and sometimes also need to look at the bottom right and left. Each direction should be able to stare at 5 to 10 minutes, especially in the horizontal direction, it is best to maintain for 10 minutes. The vast majority of patients through several days of practice can do. It is a person is unable to control eye rotation, intraoperative to limbus or muscle insertion suture, by the surgeon or assistant to control the patient's eye movement.

In conclusion, preoperative eye through the practice of slow rotation and a long time at the specified direction, can cooperate with the doctor in the operation of good operation, thus greatly reduce the corneoscleral cut, medial rectus injury and other serious complications. Moreover, because of the stable visual field of surgery, the surgeon can take a more radical excision of pterygium, do not need to be tired of dealing with the rotation of the eyeball, postoperative recurrence rate will be greatly reduced. Therefore, preoperative eye rotation is very useful.
