Abstract Details
Purpose:
The aim of this study was to analyse the efficacy and safety of Artiflex® lens implant (Ophtec BV, Groningen, Netherlands) for refractive correction of high myopia.
Setting:
Department of Ophthalmology of Centro Hospitalar Universitário de São João, Porto, Portugal
Methods:
We analysed data from 72 eyes of 40 patients (13 male and 23 female) with an average age of 37 years (range 23-53 years) and with a spherical equivalent of at least -5.0 diopters (D) that underwent Artiflex® lens implantation at our centre for myopia correction, between the months of July 2013 and December 2019. The main outcomes analysed were best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), residual refractive error, endothelial cell count (ECC) and the occurrence of procedure related complications.
Results:
At the last follow-up there was a significant visual acuity improvement with a final mean LogMAR UCVA of 0.03±0.05 (p=0.001) and BCVA of 0.01±0.04 (p=0.001). The spherical equivalent decreased from -9.92±2.52D at baseline to -0.18±0.56D at the last follow-up after lens implantation (p=0.001). The mean ECC decreased from 2791±428 cells to 2602±447 cells at the last follow-up (p=0.001). During follow-up, nine eyes needed intra-ocular lens repositioning following traumatic events, with no other identifiable complications.
Conclusions:
In our experience, the foldable Artiflex® phakic intraocular lens is an effective, safe and stable treatment of high myopia, being particularly suited for myopic patients where laser surgery is not an option. Follow-up is necessary to monitor the density of endothelial cells and other possible complications, as well for evaluation of refractive stability.
