The Lazy-T procedure is used to correct moderate-to-severe punctal ectropion in the lower eyelid. It includes full-thickness wedge resection of the medial lower eyelid and horizontal tarso-conjunctival diamond excision inferior to the lower punctum. However, the skin wound vertical to the relaxed skin tension lines is often conspicuous and horizontal excision of a part of the tarsus may impair function of the meibomian gland. In this study, the authors developed a modified Lazy-T procedure, which includes subciliary incision, pentagonal tarso-conjunctival resection, and medial spindle excision for submerging the vertical wound after suturing the pentagonal tarso-conjunctival resection under the skin flap and minimizing damage to the tarsus. The modified Lazy-T procedure was applied in 4 eyelids of 3 patients and achieved good anatomical results with cosmetically acceptable postoperative appearances and no remarkable complication.
Lazy-T手术用于矫正下睑中重度泪点外翻。它包括下睑内侧全层楔形切除以及下泪点下方的水平睑板结膜菱形切除。然而，垂直于松弛皮肤张力线的皮肤伤口往往很明显，部分睑板的水平切除可能会损害睑板腺的功能。在本研究中，作者开发了一种改良的Lazy-T手术，包括睫毛下切口、五边形睑板结膜切除以及内侧梭形切除，以便在将五边形睑板结膜切除缝合于皮瓣下后埋没垂直伤口，并将对睑板的损伤降至最低。改良的Lazy-T手术应用于3例患者的4只眼睑，取得了良好的解剖学效果，术后外观在美容上可以接受，且无明显并发症。
