Abstract Details

Purpose:

To evaluate the refractive, functional and quality of vision related results in a group of patients with refractive lens exchange and implantation of a trifocal intraocular lens (IOL).

Setting:

Refractive Surgery Department. Institut Català de Retina, Barcelona (Spain)

Methods:

Retrospective analysis of 135 eyes (71 patients) operated by one surgeon (FDM) using the technique of clear lens phaco-aspiration and implantation of the trifocal IOL FineVision Micro F® (PhysIOL, Liège, Belgium). The follow-up period was of 12 months. Results were evaluated according to changes in sphere, cylinder and spherical equivalent (SE), predictability and stability, distance, intermediate and near visual acuity (UDVA, UIVA, UNVA), and defocus curve. Stability and predictability were considered. Quality of vision was evaluated according to changes in high order aberrations (HOA), contrast sensitivity (CS) and results of the VF-14 test and a general satisfaction survey.

Results:

Sphere, cylinder and SE were 0.29±0.41, -0.44±0.33 and 0.07±0.4, 89.4% presented final SE between ±0.50D. UDVA, UIVA and UNVA were 0.86±0.14, 0.96±0.2 and 0.89±0.15, with a significant improvement. Defocus curve presented a plateau morphology that demonstrated the improvement of the IVA. Efficacy for binocular DVA was 95%, and for NVP 96%. Safety was 100% for binocular DVA and 96% for binocular NVA. Average values for HOA were 0.47±0.19 with a significant decrease in CS. Final score for the VF-14 was 92.5±7.53 and 9.05±1.28 for the general satisfaction survey. Patients reported spectacle independence of 98%, and 94.1% would recommend the procedure.

Conclusions:

Refractive lens exchange surgery with implantation of a trifocal intraocular lens produces a significant improvement of uncorrected visual acuity and provides a good quality of life for the patient. The results exceed the success criteria for the efficacy index and obtain a defocus curve profile that demonstrates the improvement in intermediate vision.
