MODERN ASPECTS OF MULTIFOCAL INTRAOCULAR CORRECTION: A REVIEW

Cover Page

Abstract


During the last decade multifocal intraocular lenses (IOL) became widely used in cataract surgery and proved to be effective in recovery of visual functions. Lots of clinical studies with different multifocal IOL models showed high effectiveness of multifocal correction to achieve good visual quality for far, intermediate, and near distances. Uncorrected visual acuity at a distance is equal to multifocal and monofocal correction, while uncorrected near vision is significantly better with multifocal IOLs. Additional segment position in asymmetric multifocal IOL models did not significantly influence on visual acuity. Multiple multifocal IOL designs (bifocal, trifocal) and ADD power level provide different functional results for near and intermediate distances which allows to select the specific IOL model depending on the patient`s needs. The review covers the following aspects of multifocal intraocular correction: update for classification of multifocal IOLs, visual acuity (functional results) at different distances after multifocal IOL implantation, comparison of clinical results with different multifocal IOL designs and add power levels, influence of add segment position in asymmetric multifocal IOLs on visual quality, comparison between multifocal and monofocal correction.
