Abstract Details

Purpose:

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.

Setting:

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

Methods:

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.

Results:

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).

Conclusions:

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.
