About this study

The Clareon(R) T2 IOL and the Clareon (R) non-toric IOL will be randomly implanted in subjects determined to be appropriate for the T2 IOL. Visual acuity, low contrast acuity and contrast sensitivity will be measured 3 months postoperatively.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • candidate for cataract surgery, suitable for implantation with a low cylinder toric IOL
