The effect of unpreserved topical anaesthetic on tear film stability (0.4% oxybuprocaine hydrochloride) was investigated in a double masked randomised study in 12 healthy volunteers, using a noninvasive tear film break up technique (NIBUT). It was found that the topical anaesthetic did not reduce the pre-corneal tear film stability, contrary to the electron microscopic evidence.
在一项针对12名健康志愿者的双盲随机研究中，使用非侵入性泪膜破裂技术（NIBUT），研究了未保存的局部麻醉剂（0.4%盐酸奥布卡因）对泪膜稳定性的影响。结果发现，与电子显微镜证据相反，局部麻醉剂并未降低角膜前泪膜的稳定性。
