Clinical outcomes of implantation of multifocal IOLs Ascrysof IQ Restor +2,5, Ascrysof IQ Restor +3,0 and combined bilateral implantation in patients after cataract phacoemulsification have been compared. The multifocal lens Ascrysof IQ Restor +3,0 has been implanted bilaterally in 18 patient (36 eyes), the multifocal lens Ascrysof IQ Restor +2,5 has been implanted bilaterally in 11 patient (22 eyes), and combined bilateral implantation has been performed for 10 patients (20 eyes) (Acrysof IQ Restor +2.5 in the dominant eye and Acrysof IQ Restor +3,0 in the non-dominant). The control group consisted of 20 patients (40 eyes) with bilateral implantation of a monofocal IOL Ascrysof IQ. Combined bilateral implantation Ascrysof IQ Restor +2,5 in the dominant eye and Ascrysof IQ Restor +3,0 in the non-dominant eye can increase the range of high rates of uncorrected visual acuity nearby and in the middle distance from 40 to 60 cm in patients after cataract phacoemulsification, while maintaining high visual acuity at a distance. The results show the prospects of a combined bilateral implantation of the above IOLs after phacoemulsification of a cataract in patients who want to minimize the need for spectacle correction in the postoperative period.
Key words: multifocal intraocular lens, apodization, bifocal diffractive-refractive IOLs.
