Abstract
PURPOSE: To compare binocular static visual acuity (SVA), stereopsis, contrast sensitivity (CS) and dynamic visual acuity (DVA) of 5 combinations of bifocal intraocular lenses (IOLs), trifocal IOLs and extended-depth-of-focus (EDOF) IOLs in age-related cataract patients. METHODS: Two hundred and ninety-two eyes of 146 patients who underwent cataract surgery in the ophthalmology department of the First Affiliated Hospital of Chongqing Medical University were involved. Subgroups included group MM (33patients, bilaterally bifocal IOL, ZMB00), group TT (31patients, bilaterally trifocal IOL, AT LISA tri839MP), group XX (34patients, bilaterally EDOF IOL, ZXR00), group MX (25patients, bifocal IOL, ZMB00 + EDOF IOL, ZXR00) and group TX (23patients, trifocal IOL, AT LISA tri839MP + EDOF IOL, ZXR00). The uncorrected SVAs (UDVA, UIVA and UNVA), uncorrected DVAs (UDDVA, UIDVA and UNDVA), near and distance stereopsis, and CS were assessed 3 months postoperatively. RESULTS: Subgroups of TT, XX, MX and TX showed better UIVA than MM (bP = 0.039, 0.021, 0.035 and 0.037, respectively). MX showed better UNVA than MM and TX (bP = 0.031 and 0.013, respectively). MX group had the optimal outcomes of both near and distance stereopsis. In the UDDVA, XX group and MX group showed better outcomes than TX group at 24 fps (frames per second) (bP = 0.019 and 0.023, respectively). XX group and MX group showed optimal outcomes at all speeds of UIDVA (P = 0.001, 0.005, 0.003 and 0.005, respectively). As the speed increased, the XX group and the MX group showed better UNDVA than the MM group and the TT group (P = 0.019, 0.002 and 0.003, respectively). CONCLUSIONS: Mix-and-match implantation of bifocal IOLs and EDOF IOLs provides excellent and stable binocular visual outcomes including SVA, stereopsis and DVA in distant and near distances.
