AIM:To observe the differences of central cornea thickness, anterior chamber depth, corneal anterior curvature and corneal posterior curvature between the Kazak and the Han nationality college emmetropia students, and analyze the relationship of corneal thickness and corneal curvature.

METHODS: More than 500 students in grade one in Xinjiang Medical University for screening, selected 55 emmetropia eyes in Han nationality students and 51 in Kazak students. Sirius corneal topography was applied to the measurement.

RESULTS: Kazak and the Han nationality college emmetropia students' central cornea thickness(Kazak:0.52±0.03mm, Han:0.54±0.03mm), anterior chamber depth(Kazak: 2.97±0.31mm, Han: 3.14±0.25mm)had significant difference(P<0.05). Corneal anterior curvature and corneal posterior curvature were no significant difference(P>0.05). Han had no significant relationship in corneal thickness and corneal anterior curvature(r<0), or in corneal posterior curvature(r<0.1). Kazak had no significant relationship in corneal thickness and corneal anterior curvature(r<0), or in corneal posterior curvature(r<0.1).

CONCLUSION: There are significant differences between the Kazak and the Han nationality college emmetropia students in cornea thickness, anterior chamber depth. There is no significant relationship between corneal thickness and corneal curvature(K1, K2)in Kazak and the Han nationality college emmetropia students.
