Abstract Details


Retrospective 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 Artisan phakic intraocular lens (pIOL) for myopia.


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


Data from all myopic patients implanted with the Artisan pIOL (Ophtec, Groningen, the Netherlands) from 1998 until present time were collected for retrospective analysis. Mean preoperative age was 41.44±10.45. 191 patients (356 eyes), 130 patients (257 eyes) and 98 patients (180 eyes) completed a follow-up of 1, 5 and 10 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 0.17±0.22, 0.25±0.28 and 0.35±0.34 LogMAR respectively 1, 5 and 10 years postoperatively (p<0.01). Mean LogMAR CDVA was 0.03±0.14, 0.06±0.15 and 0.10±0.29 LogMAR 1, 5 and 10 years postoperatively (p<0.01). Mean spherical equivalent (SE) was -0.50±0.67 D, -0.90±1.09 D and -1.54±1.57 D respectively 1, 5 and 10 years postoperatively (p<0.01). After 1, 5 and 10 years, 84%, 67% and 49% of eyes were within 1.0 D of the intended correction. Mean chronic EC loss from 6 months to 5 and 10 years postoperatively was -4.90%±0.93 and -11.40%±1.64 respectively (p<0.01).


Over 10 years, uncorrected visual acuity showed a slight decline of 0.18 LogMAR due to a mean age related myopisation of -1.04 D. Best corrected visual acuity remained stable during 5 and 10 year follow up. There was a progressive annual endothelial cell loss of -1.14% that almost doubled the expected physiological endothelial cell loss of -0.6% per year.
