Visual outcomes and satisfaction in patients with high myopia after cataract surgery with trifocal intraocular lens implantation.

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.
