Refraction during incipient presbyopia: The Aston Longitudinal Assessment of Presbyopia (ALAP) study

Conclusion The incidence of a myopic shift in refraction during incipient presbyopia does not appear to be as large as previously indicated by retrospective research. The changes in axis indicate ocular astigmatism tends towards the against-the-rule direction with age. The structural origin(s) of the reported myopic shift in refraction during incipient presbyopia warrants further investigation.
