The Multifocal IOLs segment is primarily differentiated by application and type. In terms of application, three core uses dominate: cataract surgery, refractive surgery, and presbyopia correction. Cataract surgery accounts for the largest share, driving volume because multifocal lenses replace the clouded natural lens and simultaneously address distance‑ and near‑vision deficits. Refractive surgery leverages multifocal designs to reduce dependence on spectacles after laser procedures, while presbyopia correction targets patients seeking spectacle‑free near vision without cataract involvement. Regarding type, the market splits into diffractive, refractive, and hybrid lenses. Diffractive multifocals are further sub‑typed into step‑wise and aspheric designs, each creating distinct focal points through concentric rings. Refractive lenses include apodized and non‑apodized variants that modify surface curvature to distribute light. Hybrid models combine diffractive optics with refractive surface shaping to balance visual quality and contrast sensitivity. Collectively, these application and type sub‑segments define the overall Multifocal and Trifocal Intraocular Lenses (Multifocal and Trifocal IOLs) segmentation, influencing pricing, adoption rates, and regional market share.
