Multifocal Pilot Study: Refitting Drop Outs

2014-07-23 21:13:33 | BioPortfolio

Summary

The objective of the study is to assess the visual performance and the success rate of AIR OPTIX Aqua multifocal lenses compared with a contact lens and reading glasses combination.

The hypothesis of the study is that the AIR OPTIX Aqua multifocal lenses will offer a more improved contact lens wearing experience than single vision contact lenses with over-reading spectacles.
