AIM: To explore the relationship between refraction and the ocular components of Uygur college students.

METHODS: In this article, 475 Uygur college students(950 eyes)with different refractive status were enrolled. Measurements of axial length, anterior chamber depth, the corneal curvature(all by IOLMaster)and refraction. Nine eyes were excluded duo to an impact on refractive state of eye disease. The correlation between refraction and ocular components(axial length, anterior chamber depth, corneal curvature)were analyzed by statistical methods.

RESULTS: Uygur students in 941 eyes with refractive change, from -13.5～+8.00D, the axial length of the eyes was got short from long one, anterior chamber depth was becomed shallow from deep one, and the average corneal curvature changes were becomed flat from convex one. According to the different refractive state, they were divided into 7 groups, and there was significant difference for comparisons of axial length in each group(P<0.05). Anterior chamber depth and the average corneal curvature had no statistical difference between the refractive state of the situation(P>0.05). The correlation coefficient of spherical equivalent and ocular axial length, anterior chamber depth and the average corneal curvature were -0.834, -0.547, -0.208(P<0.01). The multivariate linear regression formula was D=83.229-2.150AL+2.171ACD-0.939K.

CONCLUSION: Changes in refractive factors between Uygur students determine the refractive state of the eyes, and provide the basis for the occurrence and development of Uygur refractive status.
