Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Axial length	To compare axial length growth of white European myopic children wearing Menicon Z Night orthokeratology contact lenses to a control group of distance, single-vision glasses and soft contact lens wearers. Measurements of axial length were taken with the Zeiss IOLMaster (Carl Zeiss Jena GmbH, Jena, Germany). Three separate measurements of axial length were recorded per subject and per visit, and a mean obtained.	11 years
