Then, the conjunctiva is cut annularly along the corneal limbus, and the conjunctiva and subconjunctival tissues are separated downward below the equatorial line;

Then separate the four rectus abdominis muscles, sew them at the stopping point of rectus abdominis muscle and cut them into a figure of eight. It must be noted that the medial rectus muscle should leave 0.5mm tendon to pull the eyeball;

The optic nerve scissors should be separated from the upper inside, and the optic nerve should be cut after the goal is scored. Then clamp the stump of rectus muscle in the eyeball, gouge out the eyeball, and cut off tiny neurovascular tissues such as the upper and lower oblique muscles against the sclera.

After the eyeball is taken out, fill the orbit with wet gauze or hemostatic iron ball, and take it out after hemostasis. Finally, suture the broken ends of internal and external rectus muscle, and suture the broken ends of upper and lower rectus muscle. Tenon capsule and conjunctiva were sutured in layers, and then pressure bandaged.
