Corneal curvature and thickness were measured in 10 persons after overnght wearing of disposable hydrogel contact lens in the right eye only. The values in the left eye served as control. The cases were all females. The ages ranged from 19 to 27 years, average 22.4 years. The corneal thickness in the left eye increased by 1 to 27μm, average 16μm. This value accounted for 2.9% of corneal thickness the previous day. The corneal thickness in the right eye increased by 23μm to 72μm, average 50μm. This value accounted for 9.5% of the conreal thickness. There were no significant changes in the corneal curvature between both eyes. Above findings suggest the inherent danger of continuous wearing of disposable contact lens.
