Abstract

Purpose To evaluate and compare the visual performance of a trifocal and a trifocal-toric intraocular lens (IOL) based on the same diffractive platform. Methods Prospective non-randomized comparative study enrolling 142 eyes of 77 patients (age 40-73 years) undergoing uneventful phacoemulsification lens surgery. Two groups were differentiated according to the implanted IOL: trifocal group, 98 eyes (50 patients) implanted with the trifocal diffractive IOL AT LISA tri 839MP (Carl Zeiss Meditec), and trifocal-toric group, 44 eyes (27 patients) implanted with the trifocal-toric diffractive IOL AT LISA trifocal-toric 939MP (Carl Zeiss Meditec). Visual and refractive changes were evaluated 3 months postoperatively. Results No significant differences between groups were found in postoperative refraction (p ≥ 0.144), monocular and binocular uncorrected intermediate visual acuity (UIVA; p = 0.519 and 0.398, respectively) and binocular uncorrected near visual acuity (UNVA; p = 0.073). In contrast, significantly better monocular and binocular uncorrected distance visual acuity (UDVA; p ≤ 0.002), as well as monocular UNVA (p = 0.005), were found in the trifocal group. A postoperative spherical equivalent within ± 1.00 D was found in 98 % and 100 % of eyes in the trifocal and trifocal-toric groups, respectively. Postoperative binocular UDVA, UIVA and UNVA of 20/30 or better were found in 100, 95 and 100 % of eyes, and in 96.3, 95.8 and 90.9 % of eyes in the trifocal and trifocal-toric groups, respectively. Conclusions The evaluated trifocal and trifocal-toric IOLs both provide a successful restoration of the visual function after cataract surgery, with good levels of refractive precision, as well as UIVA and UNVA.
