“T形”(横置的“T”)矫正术用以治疗严重的下泪点外翻。手术原理是利用垂直下睑缘的全层“V”形切除来矫正眼睑在水平方向的松弛;而用平行于睑缘切除部分睑结膜和睑板的方法来矫正眼睑在垂直方向的松弛。二条伤口缝合后恰如一个横置的“T”字,这时下泪点就恢复了原来的生理位置。局麻或全麻均可采用。局麻时应尽量减轻组织的肿胀和变形。手术方法如下: T-shaped (transverse “T”) orthosis is used to treat severe eroded tears. The principle of operation is to correct horizontal eyelid relaxation by using full-thickness “V” resection of the vertical lower eyelid; and to correct the eyelid vertical relaxation by resecting part of the conjunctiva and tarsal plate parallel to the eyelid. Two wound suture just as a transverse “T” word, then tear down the point to restore the original physiological position. Local anesthesia or general anesthesia can be used. Local anesthesia should try to reduce tissue swelling and deformation. Surgical methods are as follows:
