Comparison of visual and refractive outcomes after implantation of a new diffractive trifocal toric lens, a trifocal lens and a monofocal toric lens

Abstract

PurposeTo evaluate a diffractif trifocal toric intraocular lens (IOL) comparated with a trifocal IOL and a monofocal toric IOL.MethodsThis retrospective comparative study included patients with visually significant cataract or presbyopia who were scheduled for lensectomy and implantation of IOL. They were included in 3 groups according to the IOL implanted: multifocal group, multifocal toric group and toric group. At 1 month postoperatively, visual acuity (VA) at long and near distance, and refractive outcomes were examined.Results70 eyes of 45 patients were included. 21 eyes in the multifocal group, 22 in the multifocal toric group, and 27 in the toric group. The mean age of patients was 70.7 years +/− 10.6 (range 52–91 years). Postoperatively, the mean refractive astigmatism decreased to 0.71D, 0.77D and 0.72D respectively in the 3 groups. The distance uncorrected VA was 0.13logMar +/− 0.11 for multifocal group, 0.13logMar +/− 0.16 for multifocal toric group and 0.12logMar +/− 0.11 for toric group. There were no statistically differences between the 3 groups for the uncorrected distance VA, and between multifocal group and multifocal toric group for the uncorrected near VA.ConclusionsDiffractif trifocal toric IOL provided useful VA at any distance. The addition of a toric surface to the aspheric diffractive multifocal IOL resulted in a comparable visual performance.
