Participants in the intervention groups will be reviewed at 6, 12, 18 and 24 months after the dispensing visit. During these visits the majority of measurements undertaken during the initial assessment will be repeated along with routine contact lens aftercare. Eye drops to relax the eye muscles and dilate the pupils will be instilled at the 12 and 24 month visits. For the anisohyperopic subjects, if the level of hyperopia in the more hyperopic eye reduces to a level that matches the less hyperopic eye then the intervention will be stopped. For the non-anisohyperopic subjects, the intervention will be stopped when the refractive error has reached a mean spherical error of +0.50D. At the end of an intervention period of 24 months the participants will be assessed after a period of 6 months to assess the growth of their eyes post-intervention.
