  1. Statistical significance was tested using Student’s t-test. Missing data and data with gross errors were not included in the analysis
  2. ACD = anterior chamber depth; AL = axial length; CP = corneal power; D = diopter; DM = diabetes mellitus; LT = lens thickness; IOP = intraocular pressure; SD = standard deviation; SE = spherical equivalents
