When the design of open canthus repair fails, the influence of tension will also be considered, and the surgical method will be selected according to the direction. The outermost angle of the inner canthus should not exceed the vertical line of the nose, otherwise the distance between the two eye tips will be too close. In order to make the eyes look more energetic, the tear mound is exposed at most 2/3 in the design. The failed design of opening the corner of the eye is slightly lower than the horizontal line of the long axis of the eyes, so the effect of the operation will be more natural.

The failed corner of the eye is difficult to repair, and it is necessary to know the indications of the operation well. It is best to choose different repair methods in different situations. Generally, patients can achieve good results after failing to repair the corner of their eyes, and patients do not have to worry about reoperation. The effect of the operation can be recovered well in a certain period of time. Repairing the failed canthus opening can improve the last operation.

There are also some precautions after the failure of canthus surgery, such as avoiding water in the surgical site within 5 days after the failure of surgery. Ensure the cleanliness of the failed canthus incision and repair operation site to prevent infection. If there is blood scab or secretion on the wound, it can be wiped with sterile physiological saline.
