Article for CME CreditComparison of iris-fixed Artisan lens implantation with excimer laser in situ keratomileusis in correcting myopia between −9.00 and −19.50 diopters: A randomized study

Study design and patient population
Between April and November 1998, 90 eyes of 61 consecutive patients were enrolled in a prospective, randomized study. Forty-five eyes received the Artisan lens (Ophtec BV, Groningen, The Netherlands) and 45 eyes received LASIK. The procedure assigned to each eye was randomized, using a random number table. Patients selected for the study met inclusion criteria, including age of at least 21 years, documented stable refraction for 1 year, spherical equivalent refraction between 9.00 and 19.50 D
Results
Of the 90 eyes included in this trial, 45 eyes (50%) had Artisan lens implantation (Artisan eyes) and 45 eyes (50%) had LASIK (LASIK eyes). Patients ranged in age from 21 to 47 years (mean, 33.7 ± 7.1 years). Of the 61 patients, 37 (60.7%) were female. Eighteen patients (29.5%) had Artisan lens in one eye and LASIK on the other (Artisan/LASIK subgroup), 5 patients (8.2%) had Artisan lens in both eyes, 6 patients (9.8%) had LASIK on both eyes, 17 patients (27.9%) had Artisan in one eye, and 15
Discussion
A high follow-up examination rate (mean, 94.0%) was achieved throughout the first year. This is explained by the enrollment of only those patients who said that they could follow the postoperative examination schedule given to them before surgery.

2015, Journal of Cataract and Refractive SurgeryCitation Excerpt :In this study, we have reported the 5-year safety, efficacy, refractive predictability, and stability of the Artisan pIOL to correct high myopia, and have introduced a new linear model predicting endothelial cell loss after pIOLs implantation. Several clinical reports1,3,8–11,15–20 have demonstrated that stabilization of the postoperative refraction occurs within the first few years after surgery with a high safety index. The 5-year follow-up obtained in the present study showed comparable results on refractive stability; indeed, 5 years after Artisan pIOL implantation, the mean SE was −0.75 ± 0.74 D.
