    Comparative analysis of the functional results after implantation of various EDOF IOL models

    The aim of the current work is a comparative assessment of extended focus intraocular lenses (IOL) based on the most important criteria for the patient – visual acuity at different distances and the pattern of subjective visual sensation

    The following IOL models were compared: Comfort (Teleon), Tecnis Symfony (J&J), Ac.JQ Vivity (Alcon), Ray One EMV (Rayner), Tecnis Eyhance (J&J), Lux Smart (Bausch & Lomb). 180 patients were under observation after phacoemulsification, with bilateral implantation of the above named IOL. All patients were divided into 6 groups depending on the type of lenses, their visual acuity at various distances was determined in the postoperative period and they were asked to fill out a 14-questions questionnaire.

    Conclusions. Visual functions in patients after IOL implantation were slightly different from one another, which makes it possible to recommend them differentially to each patient depending on his age, gender, occupation and habits. Implantation of the IOL Comfort with a low addition more often than other lenses provides better visual acuity at a short distance, however distance visual acuity usually does not reach its maximum values. One fourth of patients with the IOL Comfort report halos and spots of light in the dark. Distance visual acuity is the highest in case of Symfony, Vivity, Eyehance IOL implantation, however, at medium and close distances it is usually insufficient for reading of an ordinary text. One third of patients with Symfony IOL implantation report halos around light sources in the dark. Lenses with a dosed combination of spherical aberrations (Ray One EMV, Lux Smart) are characterized by highly balanced values of visual acuity at different distances. There are complaints of light phenomena at night, but they are minimal.
