To evaluate the efficacy, stability, quality of vision and safety of the foldable anterior chamber iris supported phakic Intraocular lens (IOL) Toric Artiflex® (Ophtec) for the correction of myopia with astigmatism.
Ophthalmology Department, Centro Hospitalar do Porto - Hospital de Santo António, Porto, Portugal
Seventy six eyes of 54 patients with moderate to high myopia (-0.50 and -13.00 Diopters (D)) and astigmatism (-0.75 to -5.25 D) were implanted with Toric Artiflex®. Mean implanted spherical and cylindrical powers were -1.00 ± -13.00 D and -1.00 ± -5.00 D, respectively. Follow-up period ranged from 6 to 30 months. Outcome measures were uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), refraction and intraocular pressure. Morphometric evaluation (with Orbscan II® and Pentacam HR®), endothelial cell density (with specular microscopy ICONAN®) and contrast sensitivity function under photopic and mesopic conditions were assessed.
All eyes achieved post operative refractions within +/- 1.00 D (spherical equivalent) of the intended refraction, with astigmatism raging from 0.00 to 0.75 D. No eyes experienced loss of BSCVA. Post operative UCVA was ? 8/10 in every case except two eyes with amblyopia that achieved 6/10. There was no significant decrease in ECD at the end of follow-up. Contrast sensitivity function was similar at all spatial frequencies. There was one case of traumatic haptic subluxation which was successfully resolved with a second surgical procedure and few cases of pigment precipitates. No major complications (cataract, glaucoma or endophthalmitis) occurred. Patient satisfaction was very high.
The Artiflex® Toric phakic IOL revealed a stable and predictable visual results, with no major safety-concerned complications and good satisfaction, in the correction of moderate to high myopia and astigmatism.
