A retrospective analysis of lens binding was performed using records from 279 cases of overnight wear of rigid gas permeable (RGP) lenses in a variety of materials and designs. The overall incidence of lens binding on eye opening was 22%. Typically, the lens was bound nasally, became mobile spontaneously in less than 1 h, and produced staining of the central cornea and inferior conjunctiva. A corneal indentation ring was noted in 53% of eyes that experienced a bound lens. A statistical analysis was performed to determine whether RGP lens binding was associated with particular lens parameters, patient characteristics, or lens fitting factors. Overnight lens binding was found to occur more frequently with lenses of large diameter, flat base curve and minimal axial edge lift, fitted "on-K" or flat relative to central corneal curvature, and exhibiting less than optimal on-eye lens movement before eye closure.
利用279例各种材质和设计的硬性透气性（RGP）镜片过夜佩戴记录进行了镜片黏附的回顾性分析。睁眼时镜片黏附的总体发生率为22%。通常，镜片在鼻侧发生黏附，在不到1小时内自行活动，并导致中央角膜和下结膜染色。在53%经历镜片黏附的眼中观察到角膜压痕环。进行了一项统计分析，以确定RGP镜片黏附是否与特定的镜片参数、患者特征或镜片适配因素相关。发现过夜镜片黏附在大直径、平基弧和最小轴向边缘提升的镜片中更频繁发生，这些镜片相对于中央角膜曲率“平贴”或较平，并且在闭眼之前显示出低于最佳的眼内镜片移动。
