目的：用扫描电子显微镜(SEM)观察软性接触镜(CL)配戴者与非CL配戴者角膜上皮细胞形态的差异。方法：对10例(10只眼)戴软性接触镜患者和10例(10只眼)非软性接触镜患者在准分子激光屈光性角膜切削术前摘除角膜上皮进行横断面观察。结果：两组角膜上皮细胞微绒毛数量差异无统计学意义(P=0.19)。软性CL佩戴者和非CL佩戴者分别为20%和80%(P=0.01)。CL患者对CL有较好的耐受性。结论：即使在无CL症状的情况下，CL佩戴者在扫描电子显微镜下也有明显的上皮粘液减少。
Purpose: To use scanning electron microscopy (SEM) to assess differences in corneal epithelium features between soft contact lens (CL) wearers and non-CL wear control.Methods: In a cross-sectional survey, the corneal epithelium removed before photorefractive keratectomy in 10 soft CL wearers (10 eyes) and in 10 non-CL wearers (10 eyes) was evaluated with SEM. The aim of the study was to assess ultrastructural differences in corneal epithelium between the 2 groups.Results: No statistically significant difference was present between the 2 groups as concerns the number of microvilli (P = 0.19). An amount of epithelial mucus > 20% was detected in 20% of soft CL wearers and in 80% of non-CL wearers (P = 0.01). A good tolerance to CL was referred by CL wearers.Conclusion: A significant reduction of epithelial mucus at SEM evaluation was present in the CL wearers even in absence of complaints referred to CL.
