About this study

VTI has an FDA cleared soft contact lens product. Its optical design creates an enhanced depth of focus (EDOF), which provides clear distance, intermediate, and near vision. This study is to quantify the enhanced depth of focus and visual impact.

Read the detailed description

This study will develop defocus curves for Baseline best corrected spectacle refraction and then for the EDOF lens used in this study. A comparison of thge depth of focus for each condition will be made.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

LogMAR Visual Acuity (time frame: 4 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
