About

The goal of this clinical trial is to learn about the influence of artificial tears on measurements of healthy eyes with three different devices. The main questions it aims to answer are:

  • Do artificial tears alter the measurements of the corneal surface
  • Is there a difference between the devices used in this study

This is relevant because high quality measurements improve the postoperative outcome after cataract surgery.
