Data are presented as means (SDs). Absolute differences are defined as HAL—SVL; relative differences are defined as absolute differences/values of SVL. Abbreviations: IXT, intermittent exotropia; HAL, spectacle lenses designed with highly aspherical lenslets; SVL, single vision spectacle lenses; NFV, negative fusional vergence; PFV, positive fusional vergence; PD, prism diopters. |
