The purpose of the study is to determine if visual function is improved with implantation of a low-cylinder toric intraocular lens, relative to a non-toric intraocular lens.
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.
