Modern Approaches to Dysphotopsia Analysis, Assessmentof Patient Satisfaction and Spectacle Independence After Multifocalintraocular Correction: Review

Abstract

The core target of multifocal IOLs implantation is to provide advanced visual quality at different distances without spectacle or contact lenses that can be valuable when monofocal IOLs are implanted. Patients with monofocal IOLs need spectacles or contact lenses for the near and intermediate distance's vision. Multifocal intraocular lenses due to the optical part construction provide spectacle independence for patients in the postoperative period. The aim of this review was to analyze the modern approach to the several aspects of multifocal intraocular correction: spectacle independence, dysphotopsia, patient satisfaction. Patients’ questionnaire after surgery provides the data for evaluation of the quality of life, vision satisfaction at all range of distances on different levels of illumination, and patient activities of daily living. During the long period, a photic phenomenon (dysphotopsia) had been discussed in the literature as the principal reason for decrease of patients satisfaction with the treatment and lens explantation. Recently, high grade of spectacle independence and low risk of photic phenomena after modern multifocal IOLs implantation determine high-level patient satisfaction after cataract surgery. Multifocal intraocular correction is the effective technology for restoring passive accommodation that the wide range of the clinical studies proved. This review analyzes 33 studies (32 clinical studies and 1 metaanalisis) published in international peer-reviewed targeted titles.

Multifocal Intraocular Lenses Clinical Assessment. Patient Selection for Multifocal Intraocular Correction

“…Оценка субъективных особенностей также необходима, поскольку пациенты с идеальным результатом проведенной операции могут быть недовольны, если в предоперационном периоде не были учтены все нюансы. Пациентам следует в обязательном порядке знать о возможности развития световых явлений и возможной необходимости очковой коррекции [35]. При отборе пациента на мультифокальную интраокулярную коррекцию важно понять его образ жизни, зрительные потребности и ожидания от операции, провести подробный опрос об условиях работы и досуга, а также о количестве времени, проведенного в этих условиях.…”
