Effects of blue-light-filtering intraocular lenses on contrast sensitivity in patients with glaucoma.

To compare the effects of blue-light-filtering intraocular lenses (BF-IOLs) and conventional ultraviolet-blocking intraocular lenses (UVB-IOLs) on contrast sensitivity in patients with concurrent cataracts and glaucoma. This prospective randomized comparative interventional study enrolled glaucomatous patients with concurrent cataracts scheduled for cataract surgery with IOL implantation at Siriraj Hospital, Bangkok, Thailand, between October 2016 and March 2018. The patients were randomly assigned to receive BF-IOLs or UVB-IOLs.
