Correlation of refractive errors and ocular components ·Brief Report· Correlation analysis and multiple regression formulas of refractive errors and ocular components Chao-Kai Chang1, Jui-Teng Lin2,3, Yong Zhang4 1Nobel Eye Institute, Taipei 100, Taiwan, China corneal power and lens power[1-5]. However, the association 2New Vision Inc., Taipei 103, Taiwan, China between refractive errors and ocular biometrics such as 3Gong-Rui Medical Technology, Xiamen 361000, Fujian corneal power, central corneal thickness, anterior chamber Province, China depth (ACD), and lens thickness are inconclusive[6-13]. The 4Department of Ophthalmology, Shandong Provincial Hospital, recent study of Hashemi et al[14] for individuals aged 40-64y, Shandong University, Jinan 250021, Shandong Province, China showed that corneal power and axial length make the greatest Co-first authors: Chao-Kai Chang and Jui-Teng Lin contribution to spherical equivalent in high hyperopia and high Correspondence to: Jui-Teng Lin. New Vision Inc., Taipei myopia. Moreover, anterior segment biometric components 103, Taiwan, China.

Department of Ophthalmology, Shandong Provincial Hospital, They also reported that lower levels of refractive errors are Jinan 250021, Shandong Province, China. yzhangmd@ attributed to an imbalance among the components of ocular hotmail.com biometrics, whereas at higher levels, ACD plays a greater role. Received: 2018-06-19 Accepted: 2018-09-10 Due to the variation and correlations of biometric components during growth, the refractive error of the eye is governed Abstract by the multifactorial condition involving corneal and lens ● The multiple regression formulas and correlation of power, ACD and vitreous chamber depth (VCD) of the eye.
