上睑板结膜与接触透镜的表面持续摩擦。使用生物显微镜和印模细胞学研究了80名软性和透气性接触透镜配戴者（各40名）和20名对照者的结膜表面。使用过滤溶解技术处理结膜印迹。采用四级分级系统对结膜进行生物显微镜和细胞学分级。印模细胞学检查是一种非侵入性、无痛的检查方法。改变后的处理技术产生了更好的细胞结构和出色的细胞细节。在生物显微镜和细胞学检查中，所有对照组均显示1级外观。发现有症状的软透镜配戴者与无症状的配戴者相比，生物显微镜和细胞学分级均显著增加。未发现透镜使用时间与生物显微镜或细胞学分级之间存在相关性。所有的变化在软性透镜配戴者中更为严重。
The upper tarsal conjunctiva is in constant friction with the surface of the contact lens. The conjunctival surfaces of 80 soft and gas-permeable contact lens wearers (40 each) and 20 controls were studied using biomicroscopy and impression cytology. A filter dissolution technique was used to process the conjunctival imprints. Biomicroscopic and cytologic grading of the conjunctivae was performed using four-tier grading systems. Impression cytology is a non-invasive, painless procedure. The altered technique of processing yielded better cellularity and excellent cellular detail. On biomicroscopy and cytology, all controls showed Grade 1 appearances. Soft lens wearers who were symptomatic were found to have a significant increase in both biomicroscopic and cytologic grades, when compared with their asymptomatic counterparts. No correlation was found between duration of lens use and biomicroscopic or cytologic grades. All changes were found to be more severe in soft lens wearers.
