Abstract Details

Purpose:

To update the clinical and visual outcomes, subjective change in quality of vision, visual function and satisfaction in a series of cases in which multifocal intraocular lenses (MF-IOLs) were exchanged with another multifocal technology due to neuroadaptation failure

Setting:

Vissum, Ophthalmology Institute of Alicante, Alicante, Spain. Division of Ophthalmology, Miguel Hernández University, Alicante, Spain

Methods:

This update include a series of   35 eyes of 20 patients that underwent explantation of a MF-IOL followed by an implantation of another MF-IOL of a different optical technology. Subjective alidated questionnaires were used to assess quality of vision, visual function and satisfaction before and after the multifocal IOL exchange. The questionnaires were the Quality of Vision (QoV) questionnaire, the Visual Function Index-14 (VF-14) and a satisfaction questionnaire. The main outcome measures were the change in subjective quality of vision, visual function, and satisfaction, and the secondary visual outcomes were refractive and visual outcomes.

Results:

Multifocal IOLexchange was successful with no significant complications.The mean time from explantation to implantation was 9 months.Quality of vision improved with a pre-exchange QoVscore of 52±3.13 to post-exchange of 42.7±23.34 (P=0.041) [Frequency subscale]. Visual function improved with a change in VF-14 score from 56.00±20.14 to 90.1±10.14 (P=0.001). For satisfaction, 85% of patients reported they would repeat the procedure. The mean uncorrected distance visual acuity(UDVA) improved significantly from 20/430 to 20/25 after the exchange(P=0.015). The corrected distance visual acuity (CDVA) improved from 20/30 to 20/22.5(P=0.001). Safety and efficacy indices reached 1.36 and 1.09 respectively

Conclusions:

Treatment of neuroadaptation failure following multifocal IOL surgery by MF-IOL exchange with a different MF-IOL optical technology improves quality of vision, visual function and increases significantly patient’s satisfaction.
