Two-Year Follow-Up of Artisan Iris-Supported Phakic Anterior Chamber Intraocular Lens for Correction of High Myopia

To evaluate the results of Artisan iris-supported phakic anterior chamber intraocular lens (pIOL) implantation in patients with high myopia.

Medical records of patients who underwent Artisan pIOL implantation for surgical correction of myopia were retrospectively reviewed. Only patients with at least a two- year follow-up were included. Spherical equivalent of manifest refractive error (SE), uncorrected visual acuity (UDVA), distance corrected visual acuity (CDVA), and endothelial cell density (ECD) were analyzed at six months, one year, and two years after surgery.

Sixty-two eyes of 42 patients were included in the study. All patients had a minimum anterior chamber depth of 3.0 mm from the endothelium. At two years, 68% of the patients were within ±0.50 D. Mean ECD was 2723 ± 311 cells/mm(2) preoperatively and 2630 ± 291 cells/mm(2) at six months postoperatively (3.4% loss, p = 0.001). ECD loss from six months postoperatively to two years postoperatively was not statistically significantly different. In three eyes (4.8%) of two patients, a temporary, steroid-induced increase in intraocular pressure (IOP) was detected.

Artisan pIOL implantation is a safe and highly effective procedure for surgical correction of high myopia. ECD loss stabilizes in the early postoperative period.
