The difference between expected and achieved refraction in both measurement methods with myopic shift in the ultrasound biometry measurement group (a) and the optical biometry measurement group (b) (). USG_expected_impl: USB expected refraction; USG_achieved_IMPL: USG achieved refraction; USG_exp._fix.: USG expected refraction; USG_achieved_FIX.: USG achieved refraction; OB_exp._impl.: OB expected refraction; OB_achieved_IMPL: OB achieved refraction; OB_exp._fix.: OB expected refraction; OB_achieved_FIX: OB achieved refraction.
