AIM: To analyze the influence of trifocal lens(AT LISA tri 839MP), Lenstec SBL-3 intraocular lens(IOL)and T SPHERIS 209M monofocal IOL implantation on vision and visual quality of patients with age-related cataract(ARC).

METHODS: Totally 114 patients(114 eyes)with ARC undergoing elective surgical treatment in the hospital between October 2018 and April 2019 were enrolled in the prospective clinical study. They were divided into LISA tri group, SBL group and monofocal group with 38 cases(38 eyes)in each group. They were treated with trifocal IOL(AT LISA tri 839MP), Lenstec SBL-3 IOL and CT SPHERIS 209M monofocal IOL, respectively. The corneal endothelium, vision and visual quality before operation and 3mo after operation were compared.

RESULTS:Three months after operation, no significant changes in corneal endothelial cell density(ECD), central corneal thickness(CCT)and the proportion of hexagonal cells in the three groups compared with preoperation(P>0.05), while the uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA)and uncorrected near visual acuity(UCNVA)were significantly improved(P<0.001). UCDVA, UCIVA and UCNVA of LISA tri group were(0.11±0.03)LogMAR,(0.17±0.05)and(0.09±0.02), which of SBL group were(0.12±0.02, 0.19±0.05, 0.08±0.02), all significantly better than(0.21±0.04, 0.24±0.07, 0.15±0.03)in monofocal group(P<0.05). 3mo after operation, the near off-glasses rate and visual satisfaction in LISA tri group were 92% and 97%, which in SBL group were 95% and 92%, all significantly higher than 66% and 68% in monofocal group(P<0.017). Compared with preoperation, the visual function and quality of life(VF-QOL)scores of the three groups significantly increased(P<0.001), which were significantly higher in LISA tri group and SBL group than in monofocal group(P<0.05).

CONCLUSION: Trifocal IOL(AT LISA tri-839MP)and Lenstec SBL-3 multifocal IOL implantation is superior to monofocal IOL in the treatment of patients with ARC, which can effectively improve vision and visual quality.
