| description | AIM: To explore correlation, consistency and comfort between traditional tear film examination methods and Oculus Keratograph. <p>METHODS: A retrospective study. Totally 101 cases(101 eyes)were diagnosed myopia and then accepted LASEK(laser epithelial keratomileusis). Non-invasive tear film break-up time(NIBUT), lower tear meniscus height(LTMH)were measured with Oculus Keratograph, fluorescein tear film break-up time(fl-BUT)and Schimer Ⅰ test(SⅠt)were performed on all cases. The correlations analysis between NIBUT and fl-BUT, LTMH and SⅠt were performed by Spearman rank correlation, consistency check between NIBUT and fl-BUT by Bland-Altman analysis. Visual analogue scale(VAS)was applied on evaluating the comfort of two kinds of examination methods. <p>RESULTS: LTMH and SⅠt showed positive correlation(<i>r</i><sub>s</sub>=0.346, <i>P</i>=0.001). NIBUT and fl-BUT showed positive correlation(<i>r</i><sub>s</sub>=0.393, <i>P</i>=0.001), 95% consistency limits range -9.62 to 14.18 in Bland-Altman Figure. There was significant difference between VAS of NIBUT and VAS of fl-BUT(<i>z</i>=-2.324, <i>P</i>=0.020). There was significant difference between VAS of LTMH and VAS of SⅠt(<i>z</i>=-8.845,<i>P</i>=0.001).<p>CONCLUSION: Oculus Keratograph can objectively measure NIBUT and LTMH, and was more comfortable than traditional tear film examination methods. It can effectively assess tear film function before corneal refractive surgery. |
