Pterygium is a common eye disease. It mainly manifests as a proliferation of wing-like neoplasms on the surface of the eye, the head of which can invade the cornea and even obscure the pupil, seriously affecting vision. The main treatment for pterygium is surgical excision. The surgery is mainly performed with a scalpel to remove the pterygium from the surface of the cornea and sclera, and often requires an autologous conjunctival flap transposition in order to reduce postoperative recurrence. The greatest risk of pterygium surgery is cutting through the cornea or sclera resulting in rupture of the eye, as well as accidental injury to the internal rectus muscle resulting in postoperative strabismus and diplopia. This serious surgical complication is often caused by the patient’s intraoperative eye movement. How can this serious complication be minimized? In general, ophthalmologists who are qualified to perform this type of surgery are basically able to control the force in their hands. The most significant risk factor comes from the patient. Many patients are not able to control the movement of the eye freely and there is an involuntary turning of the eye. When the surgeon asks the patient to look to the right during surgery, he or she is asking the patient to stare at a certain point on the right side, and to keep the eye still at that point on the right side. The patient often looks to the right and then immediately looks straight ahead again. This rotation is sometimes violent. Because the surgeon’s scalpel may be operating on the corneal surface, there is a high risk of complications at this point and damage to the cornea or sclera. If the patient’s eye is slowly turned to the surgeon’s designated position and held stationary for at least a few minutes during surgery, the surgeon’s field of view will be more stable, allowing for more complete removal of the pterygium without damaging normal tissues such as the cornea and sclera. It is my custom to communicate with the patient prior to surgery and have the patient do the following eye movement exercises. Have the patient lie flat on the bed with hands on either side of the body and head squared, basically parallel to the ceiling, without raising or lowering the head, much less twisting it. The position of the body and head should be kept constant during the whole exercise. Keep your head still, turn your eyes to the right, stare at the right side of a fixed point for 5-10 minutes, you can blink in the middle, but the eyes can not turn, the head can not turn. Eye rotation should be slow and not too violent. After practicing a few times to achieve the above requirements, you can remove the right gaze point and continue practicing. In other words, even if you can’t see anything, you can keep your eyes in a fixed eye position without turning. That is all. Because a thin layer of wet cotton is often applied to the surface of the cornea to protect it during surgery, the patient may not be able to see anything. What directions do I have to practice? Pterygium usually grows on the surface of the eye on the inside of the black eye near the nose. Then the pterygium in the right eye should be practiced to look to the right, while the left eye should be practiced to look to the left. In either eye, you should practice looking down (in the direction of your feet) and sometimes down to the right and left. It is important to be able to stare motionless for 5 to 10 minutes in each direction, especially in the horizontal direction, preferably for 10 minutes. The vast majority of patients can do this with a few days of practice. For those who are unable to control the eye rotation, sutures are made at the corneoscleral margin or at the muscle stop, and the surgeon or assistant controls the patient’s eye movement. In conclusion, by practicing slow eye rotation and staring at the designated direction for a longer period of time, the patient can cooperate well with the surgeon during surgery, thus greatly reducing the occurrence of serious surgical complications such as corneoscleral cut through and damage to the internal rectus muscle. Moreover, because the surgical field of view is stable, the surgeon can remove the pterygium more thoroughly without being tired of dealing with the spinning eye, and the postoperative recurrence rate will be greatly reduced. Therefore, it is very beneficial to practice eye rotation before surgery.
