Logarithmic aberration data from right eyes were used. The variables with a P value than 0.200 in the single-factor analysis are shown on the table. AL and SE entered the multi-factor model respectively. In the multi-factor model including AL or SE, the trend of other factors is consistent, and the coefficients are filled in according to the AL model. *, statistically significant (P<0.05); #, included in the Stepwise analysis because of clinical relevance. AL, axial length; ACD, anterior chamber depth; SE, spherical equivalent of ocular refraction; RAL, radius of the anterior lens surface curvature; RPL, radius of posterior lens surface curvatures; DIA, lens diameter; LT, lens thickness; TILT, the extent of lens tilt; DEC, the extent of lens decentration; CI, confidence intervals; T-IHOA, total internal higher order aberration; SA, Secondary astigmatism.
