最近，大直径硬性透气性接触镜（CL）（也称为“巩膜镜片”、“角膜巩膜镜片”和“角膜缘硬性CL”）的处方正在增加，用于治疗中度和重度眼表疾病（OSD）。与巩膜透镜相比，角膜缘刚性CL的直径通常较小，即，直径范围为13.0至14.0 mm，并且它们被设计成使得外周边缘压在利姆布斯上。Suncon Kyoto-CS（Sun Contact透镜有限公司，（香港）是一种新颖的角膜缘刚性CL设计，外周边缘具有多阶曲线，可在眨眼期间轻松更换泪液，可清除碎屑并防止透镜混浊或起雾，从而使患者能够享受更长的CL日常佩戴时间。在严重OSD病例中，术后角膜缘硬性CL配戴是一种非侵入性治疗方法，可以中和角膜不规则性，减少干眼症状，预防睑球粘连的进展或复发，并改善患者的视力和整体生活质量。因此，手术如羊膜移植和培养的口腔粘膜上皮移植，以及角膜缘刚性CL磨损，这是非侵入性的，是有价值的和有效的治疗策略，现在可以应用于严重的OSDs患者的管理。
Recently, the prescription of large-diameter rigid gas-permeable contact lenses (CLs), also known as “scleral lenses,” “corneoscleral lenses,” and “limbal-rigid CLs,” is on the rise for the treatment of both moderate and severe ocular surface disorders (OSDs). Compared with scleral lenses, the diameter of limbal-rigid CLs is generally smaller, that is, a diameter ranging from 13.0 to 14.0 mm, and they are designed so that the peripheral edge bears on the limbus. The Suncon Kyoto-CS (Sun Contact Lens Co., Ltd.) is a novel limbal-rigid CL design with multistep curves on the peripheral edge for easy tear exchange during blinking that removes debris and prevents lens clouding or fogging, thus allowing patients to enjoy a longer daily duration of CL wear. In severe OSD cases, limbal-rigid CL wear after surgery is a noninvasive therapeutic approach that can neutralize corneal irregularities, decrease dry eye symptoms, prevent the progression or recurrence of symblepharon, and improve the patient's visual acuity and overall quality of life. Thus, surgeries such as amniotic membrane transplantation and cultivated oral mucosal epithelial transplantation, as well as limbal-rigid CL wear, which is noninvasive, are valuable and effective treatment strategies that can now be applied for the management of patients afflicted with severe OSDs.
