Purpose. To study the influence of various types of «intraocular lens – posterior lens capsule» (IOL–PLC) interface on visual acuity (VA) and refraction pseudophakic eyes in early postoperative period after femtosecond laser-assisted cataract surgery in patients with senile cataract.Material and methods. The study included 133 pseudophakic eyes of 133 patients after femtosecond laser-assisted cataract surgery. The study did not include patients with uncorrected VA less than 0.8 on the first day after surgery; with eye axial length less than 22 and more than 26 mm; with initial posterior capsule opacification in the central area; with corneal pathology; with corneal astigmatism more than 1 diopters; with pseudoexfoliation, rigid pupil and zonal weakness and with severe somatic pathology and cognitive impairment.On the first day and one month after the surgery, corneal astigmatism, the spherical and cylindrical component of objective refraction, uncorrelated and best corrected VA were studied and the type of IOL– PLC interface was determined.Results. On the first day after the surgery, all studied eyes were divided into 3 groups depending on the type of IOL–PLC interface and dependence of postoperative refraction on relations between IOL and PLC was revealed. The greatest changes in astigmatism during month after surgery were detected in eyes with initial incomplete contact IOL with PLC and presence of folds of the latter. The most stable indexes of VA and refraction in pseudophakic eyes were in presence full contact IOL and PLC.Conclusion. Initial incomplete contact IOL and PLC was exerted greatest negative influence on VA and refraction, which led to deformation PLC in form of residual folds and local sections of fibrosis in the central area in 51 eyes (66.2%) duri ng month after surgery.
