Abstract Details


Prospective evaluation of visual and refractive parameters, efficacy, safety and endothelial cell loss in a large group of patients five and ten years after implantation with the Artiflex Toric phakic intraocular lens (pIOL) for astigmatism.


Academic Center for Refractive Surgery, University Eye Clinic Maastricht, Maastricht University Medical Center, Maastricht, The Netherlands.


Data from all myopic patients implanted with the Artiflex Toric pIOL (Ophtec, Groningen, the Netherlands) from 2005 until June 2016 were collected for prospective analysis. Mean preoperative age was 39.6±10.6. One-hundred-and-eleven patients (188 eyes) were implanted, and 85 patients (146 eyes) and 38 patients (64 eyes) completed a follow-up of 1 and 5 years, respectively. Both visual and refractive, topographic and intraocular parameters and endothelial cell density were measured preoperatively, 1 day, 1 week, 1, 3, 6 and 12 months postoperatively, followed by annual visits after completing the first year follow-up.


Mean logMAR UDVA was 0.035±0.164 and 0.083±0.164 logMAR respectively 1 and 5 years postoperatively (p = 0.002). Mean logMAR CDVA was -0.038±0.120 and -0.025±0.116 logMAR 1 and 5 years postoperatively (p = 0.16). Mean spherical equivalent (SE) was -0.26±0.62 D and -0.40±0.67 D respectively 1 and 5 years postoperatively (p = 0.001). After 1 and 5 years, 96% and 91% of eyes were within 1.0 D of the intended correction. Mean chronic EC loss from 6 months to 5 years postoperatively was -10.2% (p < 0.001).


Over 5 years, uncorrected visual acuity showed a minimal but statistically significant (p = 0.002) increase of 0.042 logMAR, whereas corrected visual acuity did not show a significant change (p = 0.16). A statistically significant (p = 0.002) myopisation of -0.40 D was witnessed over 5 years, as well as a progressive increased annual endothelial cell loss of -2.26%, which was significantly higher than the expected physiological endothelial cell loss of -0.6% per year.
