Clinical Trial Summary

The overall objective of this study is to compare the effect on simulated driving performance of multifocal (MF) versus monovision (MV) soft contact lenses in mid-late presbyopes.


Clinical Trial Description

In this crossover study, subjects wore lotrafilcon B MV (AOAMV) and lotrafilcon B MF (AOAMF) soft contact lenses as randomized for 2 weeks each. Subjects were assessed using a standardised driving simulation for each of the two treatments. A fresh pair of lenses was dispensed for the assessment. Subjects also wore lotrafilcon B single vision distance (SVD) and comfilcon A MF contact lenses during Period 1 and Period 2 respectively for an additional same-day assessment. Habitual correction was worn for an acclimatization drive in the driving simulator during Period 1. ;
