Corneal histopathology changes of the soft contact lens long-time wearers / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM:To investigate the corneal histopathology changes induced by soft contact lenses ( SCL) at diffent time. METHODS: Central and peripheral cornea structures of myopic patients wearing SCL (150 cases) and the control goups ( 150 cases ) were observed with confocal microscopy. The examinations were performed 1, 3, 5, 8 and 10a after contact lenses wearing respectively. RESULTS: After wearing the contact lenses for 5a, the cell density of corneal surface epithelial was lower in SCL wearers compared with control goups (P0.05). The SCL wearers showed a thinner thickness of central corneal epithelium than control group (P<0. 05).CONCLUSION: The corneal morphologic changes are more obvious with the longer time, and the changes is not ignored.
