  1. P value was calculated by bootstrap method, using the phakic eyes as the standard.
  2. Dataset used for evaluation of phakia compared to pseudophakia is Singapore Epidemiology of Eye Diseases study, which comprises of Singapore Malay Eye Study, Singapore Indian Eye Study and Singapore Chinese Eye Study.
  3. AUC area under receiver operating curve, CI confidence interval, SEED Singapore Epidemiology of Eye Diseases study.
