Outline of Final Research Achievements |
The mechanical friction between the upper eye lid and cornea during blinking causes various ocular surface diseases. The aim of this study was to investigate the lubricity of the ocular surface. To accomplish this, we developed an in vivo human ocular surface friction measuring system, and also developed a computational program using a algorithm for the empirical formulas to determine the lubricity. We also measured the frictional coefficient of the surface of the contact lenses with this device to invetigate the effect of the fricrion on the contact lens discomfort (CLD). The frictional coefficient of contact lenses after 2 weeks of wear increased significantly.
