Abstract
Neuroadaptation is a change in the nervous system induced by new conditions of visual perception. Various articles emphasize the importance of neuroadaptation in multifocal lens implantation. Purpose: to study the processes of neuroadaptation after implantation of multifocal IOLs. Material and methods. The study involved 118 patients after implantation of various MF IOLs, with whom a survey was conducted at different times after the operation. All patients were divided into 2 groups: 1st group – 0–3 months after MF IOL implantation (56 people), 2nd group – 3–6 months after MF IOL implantation (62 people). The questionnaire The Visual Functioning Index (VF-14) was chosen for the survey. Results. Patients of 2nd group in most cases do not experience difficulties in performing daily activities, that is, they are more satisfied with the vision obtained than patients of 1st group. Conclusion: 1) The comfort and satisfaction of patients with visual functions after implantation of the MF IOL increases over time (more than 3 months after the operation). 2) The number of dysphotopsias and other optical phenomena decreases, which is most likely due to the processes of neuroadaptation in the brain. 3) The presence of optical phenomena requires appropriate preoperative informing of patients. 4) The survey data are subjective, therefore, further study of this issue using objective methods is required. Keywords: neuroadaptation, multifocal IOLs, dysphotopsia.
