Abstract Details

Purpose:

To evaluate and compare the visual, refractive and intraocular aberrometric outcomes obtained after cataract surgery with implantation of the rotationally asymmetric refractive multifocal intraocular lens (IOL) Mplus and the diffractive trifocal IOL FineVision.

Setting:

Department of Ophthalmology (Oftalmar), Medimar International Hospital, Alicante, Spain

Methods:

A total of 45 eyes of 23 patients with ages ranging between 49 and 83 years old and undergoing phacoemulsification cataract surgery were included. This sample was divided into two groups according to the IOL implanted: Mplus group including a total of 26 eyes implanted with the rotationally asymmetric refractive multifocal IOL Mplus LS-313 (Oculentis) and Trifocal group including 19 eyes implanted with the trifocal diffractive IOL FineVision (Physiol). Both groups were equivalent preoperatively in terms of axial length, keratometry and anterior chamber depth. In both groups, the outcome of surgery was evaluated at 3 months after surgery by analyzing the distance and near uncorrected and corrected visual acuities, manifest refraction, defocus curve, and the intraocular aberrometry (iTrace system).

Results:

Distance logMAR uncorrected distance visual acuity was significantly better in Trifocal group compared to Mplus group (0.04±0.06 vs. 0.13±0.13, p<0.01) as well as near logMAR uncorrected near visual acuity (0.11±0.10 vs. 0.19±0.09, p=0.02). No statistically significant differences between groups were detected in postoperative spherical equivalent (Trifocal -0.26±0.37 D vs. Mplus -0.12±0.56 D, p=0.38). The analysis of the defocus curve showed significantly better visual acuity levels in Trifocal group for the defocus levels of -2.0, -1.5, -0.5 and +0.5 D (p≤0.01). Finally, more significant levels of intraocular higher order aberrations were found in Mplus group, especially for primary coma and (0.33±0.39 µm vs. 1.96±1.41 µm, p<0.01) and spherical aberration (-0.01±0.21 µm vs. +1.12±0.94 µm, p<0.01).

Conclusions:

The diffractive trifocal IOL FineVision provides significantly better levels of intermediate and near visual acuity than the rotationally asymmetric refractive IOL Mplus, with less induction of intraocular higher order aberrations.
