Managing dissatisfaction after multifocal intraocular lens implantation through lens exchange using monofocal or alternative multifocal IOLs

Purpose To manage patient dissatisfaction following multifocal intraocular lens (MF‐IOL) implantation by IOL exchange with either a monofocal or an alternative MF‐IOL, and to compare outcomes in these two groups. Methods MF‐IOL exchange was performed in 32 patients (64 eyes) with neuroadaptation failure. The MF‐to‐MF group involved patients who had a MF‐IOL exchanged with another MF‐IOL of a different optical profile and the MF‐to‐MO group involved patients who had a MF‐IOL exchanged to a monofocal IOL. Visual outcomes and complications were analysed. The Quality of Vision (QoV) questionnaire, Visual Function Index (VF‐14) and its Rasch‐revised version (VF‐8R) were also used to assess outcomes. Results There were no significant differences (p > 0.05) in the QoV scores between the two groups, both preoperatively and postoperatively. Preoperatively, there were no significant differences in VF‐14 scores between both groups (p > 0.05). Postoperatively, there were statistically significant differences in VF‐14 (total score, intermediate vision and near vision) in favour of the MF‐to‐MF group (p
