Abstract:

Multifocal intraocular lenses(MIOL)form multiple focal points through refractive or diffractive principles,enabling patients to achieve full-range vision for distance,intermediate,and near.Their optical designs are categorized into three main types:refractive,diffractive,and hybrid.Refractive types use concentric rings or sectors for focal division,being susceptible to pupil reflex;diffractive types employ step diffraction gratings for light distribution,balancing light energy but reducing contrast sensitivity;hybrid types combine the advantages of both refractive and diffractive principles to achieve multifocal synergy.Extended depth of focus types can reduce visual disturbances by expanding the depth of field.Grasping MIOL product characteristics and their appropriate application can enhance clinical outcomes.

Key words: Multifocal intraocular lens, Cataract
