Abstract
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 1mo and 3mo, and defocus curve examination at 3mo 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 1mo after the surgery was slightly better than that after 3mo (P=0.026). The defocus curve after 3mo 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 3mo 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 3mo 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.
