Abstract
Poor stability of the precorneal tear film causes dry eye symptoms and has detrimental effects on the optical function of the eye. In 50 patients with dry eyes the local instillation of artificial tears significantly improved contrast sensitivity (P < 0.001), using the Vision Contrast Test System 6500. In the untreated eyes no significant changes were found to occur (P = 0.56).
摘要
角膜前泪膜稳定性差会导致干眼症状，并对眼睛的光学功能产生不利影响。在50例干眼患者中，使用视觉对比测试系统6500，局部滴入人工泪液可显著提高对比敏感度（P < 0.001）。在未治疗的眼睛中未发现显著变化（P = 0.56）。
