Summary

This study tested two different lens approaches for cataract surgery: one group got two different extended-depth-of-focus lenses (one in each eye), and the other got the same trifocal lens in both eyes. The goal was to see which caused fewer halos and better vision. 36 adults having cataract surgery in both eyes took part. Researchers measured halo size and visual sharpness three months after surgery.
