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 98â% and 100â% 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 100â% of eyes, and in 96.3, 95.8 and 90.9â% 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.
