Implanting an Artisan phakic IOL to correct high myopia can cause a small increase in higher-order aberrations and a temporary decrease in contrast sensitivity, a prospective study found.
So-Hyang Chung, MD, and colleagues in Seoul, Korea, measured higher-order aberrations and contrast sensitivity in 25 eyes of 15 patients implanted with the Artisan phakic IOL (Ophtec) for myopia greater than 8 D. At 1 month follow-up, the researchers found that, under photopic conditions, total higher-order aberrations increased slightly and contrast sensitivity significantly decreased at all cycles per degree. However, contrast sensitivity had returned to baseline at 3 months follow-up, the authors reported.
Uncorrected logMAR visual acuity had improved from 1.58 preoperatively to 0.22 at 3 months follow-up, and spherical equivalent refraction averaged 0.77 ± 0.34 D, according to the study, published in the April issue of Ophthalmologica.
Advanced Medical Optics markets the Artisan IOL in the United States under the trade name Verisyse.
