Purpose. To analyze the “in vitro” aberrometric pattern of a refractive IOL and two extended depth of focus IOLs.Methods. A special optical bench with a Shack-Hartmann wavefront sensor (SH) was designed for the measurement. Three presbyopia correction IOLs were analyzed: Mini WELL (MW), TECNIS Symfony ZXR00 (SYM), and Lentis Mplus X LS-313 MF30 (MP). Three different pupil sizes were used for the comparison: 3, 4, and 4.7 mm.Results. MW generated negative primary and positive secondary spherical aberrations (SA) for the apertures of 3 mm (−0.13 and +0.12 μm), 4 mm (−0.12 and +0.08 μm), and 4.7 mm (−0.11 and +0.08 μm), while the SYM only generated negative primary SA for 4 and 4.7 mm apertures (−0.12 μm and −0.20 μm, resp.). The MP induced coma and trefoil for all pupils and showed significant HOAs for apertures of 4 and 4.7 mm.Conclusions.In an optical bench, the MW induces negative primary and positive secondary SA for all pupils. The SYM aberrations seem to be pupil dependent; it does not produce negative primary SA for 3 mm but increases for higher pupils. Meanwhile, the HOAs for the MW and SYM were not significant. The MP showed in all cases the highest HOAs.

Aim. Evaluation of the visual and functional results of bilateral implantation of the diffractive trifocal intraocular lens (IOL), the incidence of adverse optical phenomena and the degree of patient satisfaction. Methods. A prospective, open-label study included 82 patients (164 eyes) with presbyopia who underwent cataract phacoemulsification (n = 128) or refractive lensectomy (n = 36) with bilateral implantation of a new multifocal IOL AT LISA tri 839MP. The mean age of the patients was 61.2 ± 11.8 (32-84) years. The period of observation of patients was from 6 to 36 (18.3 ± 3.9) months. Results. After 1 year of follow-up, the increase in UCNVA was observed from 0.19 ± 0.17 to 0.89 ± 0.21, UCIVA from 0.18 ± 0.20 to 0.78 ± 0.17, UCDVA from 0.26 ± 0, 23 to 0.9 ± 0.12 (p
