Summary: 

Purpose: To 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. IQ Vivity. DFT015 (Alcon Inc., Fort Worth, TX, USA) intraocular lens in three months follow-up.

Material and Methods: A total of 18 eyes of 15 patients underwent 2.4 mm coaxial cataract surgery with an implantation of AcrySof. IQ Vivity. 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.

Results: Three months after the surgery in the emmetropic group refractive outcomes were: mean uncorrected distance visual acuity 0.04 Å} 0.05, mean best-corrected visual acuity 0.01 Å} 0.04, mean uncorrected intermediate visual acuity 0,01 Å} 0,03, mean uncorrected near visual acuity 0.15 Å} 0.09 and mean best-corrected near visual acuity 0.00 Å} 0. In the mini-monovision group: mean uncorrected distance visual acuity was 0.13 Å} 0.11, mean bestcorrected visual acuity 0.01 Å} 0.02, mean uncorrected intermediate visual acuity 0.00 Å} 0, mean uncorrected near visual acuity 0.09 Å} 0.13 and mean best-corrected near visual acuity 0.00 Å} 0. There was no significant change in corneal keratometry in flat and steep meridian (p = 0.59 and p = 0.4) in whole group. There were no intra- and post-operative complications in any of the patients.

Conclusions: AcrySof. IQ Vivity. 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.
