Dr. Nuijts, associate professor of ophthalmology, Academic Hospital Maastricht, The Netherlands, reported results of Artiflex implantation from a prospective, European multicenter study including 25 eyes of 13 patients who had at least 6 months of follow-up. He compared their outcomes with a series of 99 eyes of 65 patients with the Artisan implanted who were matched by refraction.
"The Artiflex has a silicone optic with PMMA haptics and can be put through a smaller incision that minimizes induced astigmatism to speed visual rehabilitation and improve the 'wow factor' for patients undergoing phakic IOL implantation," commented Dr. Nuijts.
To be eligible for Artiflex implantation, patients had to have spherical equivalent (SE) between –2.0 and –12.0 D with less than –1.75 D cylinder and an anterior chamber depth of at least 3 mm. Other inclusion criteria were preoperative endothelial cell count of at least 2,000 cells/mm2 , low-light pupil size not exceeding 7 mm, stable refraction, and no ocular comorbidity.
The 25 eyes with the Artiflex lens implanted represented 12 patients who had bilateral surgery and one with unilateral implantation. Patients who had the phakic IOL implanted in both eyes underwent the second surgery within 4 weeks. There were 12 females and 13 males, and their mean age was 41.5 years. Preoperatively, they had a mean sphere of –9.53 D (–6.5 to –11.5 D), mean cylinder of –0.79 D (0 to –1.75 D), and mean SE of –9.92 D (–6.75 to –12.13 D). The patients who received the Artisan implants had a mean age of 41.2 years and their mean refractions were –9.35 D (–6.5 to –11.5 D) for sphere, –0.73 D (0 to –1.75 D) for cylinder, and –9.72 D (–6.78 to –12.4 D) for SE.
