Multifocal IOL
Cataract & Refractive Surgery
Key Points
- •Patient selection is the most important factor for multifocal IOL success - macular disease, glaucoma, irregular astigmatism, and unrealistic expectations are contraindications.
- •Multifocal IOLs are very sensitive to residual refractive error - even 0.50 D of residual spherical equivalent significantly degrades performance.
- •Trifocal IOLs (PanOptix, FineVision) are the current gold standard, providing 80–90% spectacle independence for distance, intermediate, and near vision.
- •All multifocal IOLs cause some degree of photic phenomena (haloes, glare) and 15–20% reduction in contrast sensitivity - most patients neuroadapt by 3–6 months.
- •EDOF IOLs (Vivity, Symfony) offer fewer photic phenomena but weaker near vision - ideal for patients prioritising intermediate vision with minimal dysphotopsias.
