Abstract Details

Purpose:

To evaluate the visual and refractive outcomes, quality of vision, visual function and satisfaction in a series of cases in which Multifocal-IOLs (MF-IOL) were exchanged with Monofocal-IOLs (MN-IOL) due to neuroadaptation failure.

Setting:

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

Methods:

This is a retrospective case series. 35 eyes (26 patients) with neuroadaptation failure after the implantation of MF-IOLs were enrolled in the study. The explantation of MF-IOLs was followed by implantation of MN-IOLs. UDVA and CDVA (LogMAR), sphere, cylinder, spherical equivalent (SE) in diopters (D) and intraocular pressure (IOP) in mmHg were showed. Validated questionnaires including the Quality of Vision (QoV) questionnaire, Visual Function Index (Original VF-14 and Rasch revised version, VF-8R) and a satisfaction questionnaire were used. Primary outcomes were the change in subjective quality of vision, visual function, and satisfaction. Secondary outcomes were refractive and visual outcomes.

Results:

The total visual function didn’t change with VF-14 score dropping from 70.14 ± 19.99 to 63.13 ± 9.59 (p=0.157), the VF scores for far distance improved significantly from 78.98 ± 19.70 to 91.28 ± 10.34 (p=0.008) and those for near distance dropped significantly from 52.12 ± 29.23 to 23.27 ± 22.04 (p=0.001). Most of patients were not satisfied with neither the MF-IOL nor the MN-IOL implanted afterwards. After the IOL substitution, UDVA changed from 0.29 to 0.35 (p=0.495), CDVA from 0.12 to 0.12 (p=0.957), SE from -0.28 to -0.63 D (p=0.143). Safety and efficacy indices reached 0.86 and 0.85 respectively.

Conclusions:

MF-IOL exchange with a MN-IOL in patients with neuroadaptation failure appears to a feasible surgical option in order to improve the visual function for distance.
