| description | AIM: To evaluate the relationship between axial length(AL), corneal and lens refractive power, and the refractive error in children.<p>METHODS:Totally 44 children 88 eyes with refractive error who underwent retinoscopy with cycloplegia, to be measured spherical equivalent refractive error. Axial length was measured by a noncontact optical biometry(ZEISS IOL-Master), and corneal K and anterior chamber depth(ACD)were also measured by the same machine. The refractive power of the lens was calculated by using the SRK formula. The patients were divided into 3 groups, myopia(SE<0), hyperopia(SE>+0.50D)and emmetropia(0 to +0.50D). Linear Correlation and Regression were used to evaluate the correlation among the optical parameters.<p>RESULTS:Totally 44 subjects, 88 eyes, average 9.04±2.39 years, spherical equivalent(SE)-3.50D to +8.75D. Hyperopic AL was shorter than the other two groups(<i>P</i><0.05), same trend in lens power. No significant differences among the 3 groups in corneal K and ACD. There was a negative correlation between age and SE, SE and AL, SE and lens refractive power, and there was a positive correlation between age and AL, age and lens power. <p>CONCLUSION:As the children's growing up, SE trends to myopia, and AL becomes longer, and lens power is stronger. |
