The purpose of this study was to compare ease of handling and vision acuity of two multifocal contact lenses to correct presbyopia that are currently CE marked and on the UK market.
This was an interventional, prospective, open label, sequential design study. Participants wore each study contact lens on a daily disposable wearing modality for 14 ± 3 days and attended the clinic for a total of three study visits.

Overall Lens Handling
The ease of contact lens insertion and removal over the week preceding the follow-up visit measured on a 100-point visual analog scale, where 0=Very difficult, Painful and 100=Very easy, Can't feel the lenses
Time frame: 1 week
Overall logMAR Visual Acuity - Dominant Eye
The mean logMAR visual acuity of the dominant eye calculated as the mean of distance, intermediate, and near logMAR visual acuities. This value was recorded at the follow-up visit.
Time frame: 14 days
Overall logMAR Visual Acuity - Non-Dominant Eye
The mean logMAR visual acuity of the non-dominant eye calculated as the mean of distance, intermediate, and near logMAR visual acuities. This value was recorded at the follow-up visit.
Time frame: 14 days
Overall logMAR Visual Acuity - Binocular
The mean binocular logMAR visual acuity calculated as the mean of distance, intermediate, and near logMAR visual acuities. This value was recorded at the follow-up visit.
Time frame: 14 days
