Abstract：
Keratoglobus is a rare subset of noninflammatory corneal ectasia, which is a group of disorders characterized by corneal thinning, projection, and scarring. Patients with keratoglobus commonly present with poor vision. A case of advanced keratoglobus was managed by a modified phacoemulsification surgical technique using endoillumination and capsular staining with trypan blue. In this case, we present a 54-year-old man with keratoglobus. In January 2023, a modified phacoemulsification surgical technique using endoillumination was described with a video in a patient with bilateral corneal opacification, neovascularization, significant peripheral thinning, and moderate to severe corneal opacity in which cataract surgery had to be performed alone without considering penetrating keratoplasty. Postoperatively, the patient was doing well with no leaks. We may conclude that this method allows for better visualization during surgery and decreases the risk of intraoperative complications due to poor visualization in patients with severe corneal opacity.
摘要：
角膜扩张是一种罕见的非炎性角膜扩张的子集，这是一组以角膜变薄为特征的疾病，投影,和疤痕。角膜角化症患者通常表现为视力不良。通过改良的超声乳化手术技术，使用内窥镜照射和锥虫蓝的包膜染色来治疗一例晚期角膜角球。在这种情况下,我们向一名54岁的男子展示角膜角膜炎。2023年1月，在双侧角膜混浊患者的视频中描述了使用内窥镜照明的改良超声乳化手术技术，新生血管形成,显著的外周变薄，和中度至重度角膜混浊，其中白内障手术必须单独进行而不考虑穿透性角膜移植术。术后,病人情况很好，没有泄漏。我们可以得出结论，这种方法可以在手术过程中更好地可视化，并降低由于严重角膜混浊患者的可视化不良而导致的术中并发症的风险。
