BackgroundTo assess the visual and refractive outcomes of the non-diffractive extended depth of focus (EDOF) AcrySof ® IQ Vivity™ (Alcon, Fort Worth, TX, USA) intraocular lens (IOL) after bilateral implantation in patients undergoing phacoemulsification surgery. MethodsIn this prospective non-comparative study, 20 patients willing to undergo bilateral implantation of AcrySof ® IQ Vivity™ IOL were recruited at a single center (Eye Day Clinic, Athens, Greece). Pre- and post-operative clinical assessment of the patients included slit lamp examination, assessment of corrected distance visual acuity (CDVA) at 6 m, uncorrected distance visual acuity (UDVA) at 6 m, uncorrected intermediate visual acuity (UIVA) at 66 cm, uncorrected near visual acuity (UNVA) at 33 cm and optical biometry. Moreover, the presence of visual disturbances and the contrast sensitivity (CS) thresholds of all patients were assessed.ResultsThe mean ± standard deviation (SD) of monocular UDVA, UIVA and UNVA were 0.05 ± 0.08, 0.07 ± 0.09 and 0.23 ± 0.09 LogMAR, respectively. More specifically, 97.5%, 70% and 15% of eyes achieved UDVA, UIVA and UNVA of 20/25 or higher, while 6 patients in total reported mild glare, blurred vision, fluctuation in vision and/or depth perception difficulty. The mean ± SD of LogCS threshold was 1.68 ± 0.26.ConclusionsBilateral implantation of AcrySof ® IQ Vivity™ IOL could be a solution to patients seeking independence from optical aids. Further comparative studies are warranted to confirm our results. |
