Intraocular Lens Exchange Procedures Due To Quality Of Vision Concerns

To evaluate clinical and patient-reported outcomes of patients who underwent an exchange of a multifocal IOL due to quality of vision issues.

The data of patients dissatisfied with multifocal IOLs who underwent lens explant between January 2008 and June 2022 were retrospectively reviewed. The total number of eyes included in the analysis was 917 (616 patients). Refractive, visual acuity, and patient- reported outcomes prior to lens explant were compared to the last available follow-up visit after the lens exchange. The mean time between the primary IOL procedure and the exchange of IOL was 13.6 ± 11.2 months.

The secondary implanted IOLs were monofocal IOLs (66.7%), followed by other types of multifocal IOLs (e.g. IOLs with a lower near addition - 33.0%) and accommodative IOLs (0.3%). The percentage of eyes achieving 20/20 UCDVA increased from 67.5% prior to 74.6% post-exchange. Following the lens exchange, the MSE was within ±0.50 D in 71.0% of eyes and within 1.0 D in 91.6% of eyes. The percentage of eyes experiencing severe QOV symptoms decreased by 8.4% to 10.7%. The incidence of significant adverse events was low.

IOL exchange is a viable option that results in satisfactory visual acuity & decreased QOV side effects. A small minority of multifocal IOL cases will undergo an exchange, with the vast majority completing successful adaptation.
