- NCT02219997
- Lead Sponsor
- Alcon Research
- Brief Summary
The purpose of this study is to compare the reaction time (as measured by braking reaction time in seconds during simulated driving) under glare and no-glare conditions in subjects implanted with ACRYSOF® IQ intraocular lenses (IOLs) to subjects implanted with clear IOLs. This study will enroll subjects previously implanted with IOLs in both eyes for at least 3 months.
- Detailed Description
Subjects completed 2 visits to the investigational site.

- Primary Outcome Measures
Name Time Method Change in Braking Reaction Time From No-glare to Glare Visit 2, up to Day 30 Braking reaction time (time to brake, in seconds) was assessed using a driving simulator in no-glare and glare conditions. The subject was presented with a driving scenario during which an obstruction (car pulling over from either side of the road in a random fashion) was presented. Subjects braked in an attempt to avoid colliding with the obstruction, and the braking reaction time was recorded. The experiment was repeated with a glare source present. Both assessments (no-glare and glare) occurred on the same day. Change in braking reaction time was calculated as glare minus no-glare.
- Secondary Outcome Measures
Name Time Method Change in Braking Reaction Time From No-glare to Glare (Clear IOLs) Visit 2, Up to Day 30 Braking reaction time (time to brake, in seconds) was assessed using a driving simulator in no-glare and glare conditions. The subject was presented with a driving scenario during which an obstruction (car pulling over from either side of the road in a random fashion) was presented. Subjects braked in an attempt to avoid colliding with the obstruction, and the braking reaction time was recorded. The experiment was repeated with a glare source present. Both assessments (no-glare and glare) occurred on the same day. Change in braking reaction time was calculated as glare minus no-glare. This outcome measure was pre-specified for Clear IOL only.
Change in Braking Reaction Time From No-glare to Glare (ACRYSOF® IQ IOL + Placebo Filter; Clear IOL + BLF) Visit 2, Up to Day 30 Braking reaction time (time to brake, in seconds) was assessed using a driving simulator in no-glare and glare conditions. The subject was presented with a driving scenario during which an obstruction (car pulling over from either side of the road in a random fashion) was presented. Subjects braked in an attempt to avoid colliding with the obstruction, and the braking reaction time was recorded. The experiment was repeated with a glare source present. Both assessments (no-glare and glare) occurred on the same day. Change in braking reaction time was calculated as glare minus no-glare.
