Abstract
PURPOSE: To investigate the 3-month outcomes of visual performance and satisfaction of patients with high myopia after implantation of trifocal intraocular lens (IOL). SETTING: Army Medical Center of PLA, Chongqing, China. DESIGN: Retrospective case series. METHODS: Patients were divided to 2 groups according to the spherical equivalent (SEQ) (high myopia ≤-6.0 diopters [D] and nonhigh myopia >-6.0 D). Corrected distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA) at 5 m, uncorrected intermediate visual acuity (UIVA) at 60 cm, uncorrected near visual acuity (UNVA) at 40 cm, defocus curve, refraction, visual quality, and satisfaction were compared at 3 months postoperatively. RESULTS: Of 57 patients (89 eyes) enrolled, 32 eyes (36%) were highly myopic and 57 eyes (64%) were nonhighly myopic. At 3 months, both groups exhibited smooth defocus curves, with better visual acuity at 0 D, -0.5 D, and -2.0 D. Mean SEQ was -0.19 (-0.25, 0.00) D and 0.00 (-0.25, 0.00) D in the highly myopic and nonhighly myopic groups, respectively, with no significant difference ( P = .34). There were no significant differences between the 2 groups in CDVA, UDVA, UIVA, UNVA, spectacle independence, or satisfaction ( P > .05). Higher-order aberrations (HOAs) and trefoil aberration were greater in the highly myopic group ( P < .05). CONCLUSIONS: Trifocal IOL implantation provides satisfactory full-range visual acuity on the premise of no complications, with a spectacle independence rate of more than 90%. Although HOAs and trefoil aberration were greater in patients with high myopia, they achieve comparable visual acuity and spectacle independence rates, with a high satisfaction.
