Summary

This study tested a new device called the EYESTAR 900, which uses light to take detailed measurements of the eye's shape. 29 people with healthy eyes, corneal scarring, or irregular astigmatism took part. The goal was to see how well the new scanner measures eye geometry compared to an existing device. No treatment or medication was given.
