Abstract

PurposeTo present preliminary results of distance, intermediate and near visual acuity, objective and manifest refraction in two groups of patients: targeted on emmetropia and targeted on small myopia after cataract surgery with an implantation of Extended Depth-of-Focus AcrySof<sup>®</sup> IQ Vivity<sup>®</sup> DFT015 (Alcon Inc., Fort Worth, TX, USA) intraocular lens in three months follow-up.Material and MethodsA total of 18 eyes of 15 patients underwent 2.4 mm coaxial cataract surgery with an implantation of AcrySof<sup>®</sup> IQ Vivity<sup>®</sup> DFT015 intraocular lens (Alcon Inc., Fort Worth, TX, USA). Before surgery best-corrected distance visual acuity, objective and manifest refraction and corneal keratometry were evaluated. Three months after the surgery uncorrected and best-corrected distance visual acuity, uncorrected intermediate visual acuity uncorrected and best-corrected near visual acuity, objective and manifest refraction and corneal keratometry were analyzed in both groups.ResultsThree months after the surgery in the emmetropic group refractive outcomes were: mean uncorrected distance visual acuity 0.04 ± 0.05, mean best-corrected visual acuity 0.01 ± 0.04, mean uncorrected intermediate visual acuity 0,01 ± 0,03, mean uncorrected near visual acuity 0.15 ± 0.09 and mean best-corrected near visual acuity 0.00 ± 0. In the mini monovision group: mean uncorrected distance visual acuity was 0.13 ± 0.11, mean best corrected visual acuity 0.01 ± 0.02, mean uncorrected intermediate visual acuity 0.00 ± 0, mean uncorrected near visual acuity 0.09 ± 0.13 and mean best-corrected near visual acuity 0.00 ± 0. There was no significant change in corneal keratometry in flat and steep meridian (<i>p</i> = 0.59 and <i>p</i> = 0.4) in whole group. There were no intra- and post-operative complications in any of the patients.ConclusionsAcrySof<sup>®</sup> IQ Vivity<sup>®</sup> DFT015 (Alcon Inc., Fort Worth, TX, USA) provided good distance and intermediate visual acuity with the functional near. It is well tolerated with poor impact of post-operative optical phenomena. Significant gains in binocular near vision can be achieved by leaving the nondominant eye of patients with 0.50 D to 1.00 D of myopia.
