AIM: To investigate the early outcomes of vision, objective visual quality and their correlation after cataract surgery with trifocal intraocular lens implantation.METHODS: The visual examination and objective visual quality analysis using Optical Quality Analysis System(OQAS) at 1 mo and 3 mo, and defocus curve examination at 3 mo were performed in 20 patients(27 eyes) after phacoemulsification combined with trifocal intraocular lens implantation surgery.RESULTS: The uncorrected distant(UD), intermediate and near visual acuity(VA) were significantly improved after surgery(P<0.001). UDVA at 1 mo after the surgery was slightly better than that after 3 mo(P=0.026). The defocus curve after 3 mo indicated that the peak of distant vision was close to 0 logMAR, and UDVA was lower than 0.3 logMAR in the range of-1.5 D to-3.0 D. The modulation transfer function(MTF) cutoff frequency, strehl ratio(SR), Optical Quality Analysis System values(OVs), includes OV100, OV20 and OV9 after the surgery were significantly better than before surgery(P<0.001), but the objective scattering index(OSI) was significantly decreased(P<0.001). UDVA at 3 mo after the surgery had correlations with MTF cutoff, OSI, OV100 and OV20(r=-0.400, 0.431,-0.437,-0.411, P=0.039, 0.025, 0.023, 0.033). The uncorrected intermediate VA after 3 mo of the surgery had correlations with OSI and OV100(r=0.478,-0.411, P=0.012, 0.033). CONCLUSION: Trifocal intraocular lens implantation can provide good distant, intermediate and near VA, and the vision shows a well correlation with objective visual quality during early surgery.
