You may qualify if…

• The study population consisted of all adult patients (at least 65 years) who underwent bilateral cataract surgery between January 01, 2012 and January 01, 2018 within the University of Pittsburgh Medical Center (UPMC) healthcare system. To be considered bilateral and concomitant, cataract surgery had to be performed on both the left and the right eye within a 365-day period.

You may not qualify if…

• We excluded patients undergoing unilateral cataract surgery, surgery to replace or repair a previously implanted IOL, or bilateral implantation with one Blue-IOL and one Natural-IOL (i.e., mixed IOL transmission properties).
