Abstract

Purpose: To compare binocular reading performance following implantation of a Bifocal, Trifocal and EDOF MFIOL in different light and contrast conditions.

Methods: 90 Patients fluent in English undergoing phacoemulsification with bilateral MFIOL implantation using either: Bifocal/Trifocal/EDOF were included and divided into 3 groups (30 patients each). At 3 months Refraction and Salzburg Reading Desk (SRD) at patient preferred length for near and intermediate vision was noted in 100% (Photopic); 75% (Mesopic) and 30% (Scotopic) conditions.

Results: In photopic Light conditions for intermediate distances EDOF IOL patients had highest reading speeds of 207.6 (p<0.05). In mesopic conditions (near and Intermediate) Trifocal IOL group had highest reading speeds for near of 160.6 WPM (p 0.06). In scotopic condition for near and intermediate work EDOF group performed better. Conclusions: Different MFIOLs can be prescribed to different patients based on careful consideration of their needs.
