Abstract Details

Purpose:

To report long-term results of Artisan phakic intraocular lens (pIOL) to correct myopia and to propose a model predicting endothelial cell (EC) loss after pIOL implantation

Setting:

Quinze-Vingts National Ophthalmology Hospital, Paris, France

Methods:

49 patients (68 eyes) implanted with pIOLs from January 2000 to January 2009 were evaluated. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and central endothelial cell count (ECC) were determined before and at yearly intervals up to 5 years after implantation. Linear model analysis was performed to present a model that describes EC loss as a linear decrease and an additional decrease depending on postoperative loss

Results:

The mean preoperative and final spherical equivalent (SE) were, -13 ± 4.10 and -0.75 ± 0.74 diopters (D), respectively. The mean preoperative and final central ECC were 2629 ± 366 and 2250 ± 454 cells/mm2, respectively. There were no intraoperative complications for any of the eyes. One eye required surgery for repositioning the pIOL, and one eye required pIOL exchange for postoperative refractive error. The model predicted that for patients with preoperative ECC of 3000, 2500 and 2000 cells/mm2, a critical ECC of 1500 cells/mm2 will be reached at 39, 28 and 15 years after implantation, respectively

Conclusions:

Implantation of Artisan pIOL is an effective, stable and safe procedure after 5 years of follow-up. The presented model predicts EC loss after Artisan pIOL implantation, which can assist ophthalmologists in patient selection and follow-up
