About

The main purpose of this study was to identify electrophysiological predictive markers of post-correction visual comfort for presbyopic patients.

Full description

For each participant, presbyopia was compensated with contact lenses by monovision during three weeks and multifocality (three weeks again). A break of two weeks without any presbyopia compensation came in between the two phases of the test that were randomized.

All subjects were tested three times: before any compensation, after three weeks with monovsion and after three weeks with multifocality.

Each testing session was strictly the same including visual examinations and VEPs (visual evoked potentials).
