A woman in her 40s having post-laser-assisted in situ keratomileusis (LASIK) ectasia in both eyes developed acute hydrops in her right eye 19 years after LASIK. Anterior segment optical coherence tomography (ASOCT) did not reveal any Descemet's membrane break, which is usually present in acute hydrops. Corneal oedema was not resolved with conservative management, so descemetopexy with perfluoropropane (C3F8) gas was performed. Despite the descemetopexy with C3F8 gas, worsening of the corneal oedema was noted. In view of the non-resolving acute hydrops even after conventional treatment, a relaxing descemetotomy and full-thickness venting incision with descemetopexy and compression sutures were planned. The complete resolution of corneal oedema with a good visual outcome was achieved using this novel technique.
一名40多岁的女性双眼接受准分子激光原位角膜磨镶术（LASIK）后发生角膜扩张，在LASIK术后19年右眼出现急性角膜水肿。眼前节光学相干断层扫描（ASOCT）未发现通常在急性角膜水肿中出现的后弹力层破裂。保守治疗后角膜水肿未消退，因此进行了全氟丙烷（C3F8）气体后弹力层固定术。尽管使用了C3F8气体进行后弹力层固定术，但仍观察到角膜水肿加重。鉴于即使经过传统治疗急性角膜水肿仍未消退，计划进行松解性后弹力层切开术、全层排气切口并联合后弹力层固定术和压迫缝线。使用这种新技术实现了角膜水肿的完全消退，并获得了良好的视觉效果。
