Emmetropisation, squint, and reduced visual acuity after treatment

Abstract

In a sample of children used to assess the value of optical correction of hypermetropia from the age of 6 months the refraction of the most hypermetropic meridian frequently became less than 3.5 D as the children grew. When this occurred, the incidence of squint was significantly less (p<0001) and the last known acuity after treatment was significantly better (p<0001) than when it did not. This process of emmetropisation appears to have been impeded by the consistent wearing of hypermetropic spectacle correction from the age of6 months.
