Analyse The Result Of 900 Eyes Hanzu College Students's Refractive Factors

Objective: To measure and analyze the relation between the result of length axis,lens thickness,vitreous depth,cornea diopter ,anterior corneal surface semidiameter and the different refration status. Methods: 474Hanzu college students was collected from the Xinjiang Medical University,Tropicamide was applied to 900 eyes of 474 college students at the age of 18-24 for three times successively, Then optometry for diopter,A-ultrasonic biometry for length axis,lens thickness,vitreous depth,cornea diopter ,anterior corneal surface semidiameter .The data was analyzed with SPSS and conclued the relationship between the diopter and refractive factors. Results: Among 474 cases measured and analyzed, There were no significant distinguish between male and female in emmetropia about length axis, vitreous depth , cornea diopter in the adult years of life. The axial length of emmetropia is longer than the axial length of hyperopia , The axial length of myopia is longer than the axial length of emmetropia ,the level of myopia has apositive correlation with len gth axis , vitreous depth . The axial length of eyeball was gradually increased accompanying with the increases of diopter. Conclusions: The different refractive status depend on the mate of the different refractive factors. The axial length of eyeball was the chief factor influencing the level of myopia.
