SAN FRANCISCO — Four multifocal IOLs have “effective functional systems at all distances and limited side effects,” said Ulrich M. Klemen, MD, here at the American Society of Cataract and Refractive Surgery meeting.
Dr. Klemen spoke about four lenses: The Array 2, ReZoom and Tecnis (Advanced Medical Optics) and the AcriTwinSet (AcriTec). He said though the three-piece, hydrophilic acrylic AcriTwin has not been approved for use in the United States, it is widely used in Europe, so it was included in the study.
Dr. Klemen randomized 60 eyes of 40 patients who had a mean baseline visual acuity of 0.8 to receive one of the lenses. All patients had binocular implantation within 1 week.
“We have excellent functions for both near and far,” he said.
After implantation, 15% of the patients with the Array used spectacles, compared with 10% who had the AcriTwin, 12% who had the ReZoom and 10% who were implanted with the Tecnis. A total of 10 eyes developed halo or glare: three eyes with the Array, two eyes with both the AcriTwin and ReZoom lenses and one with the Tecnis.
Dr. Klemen said he asked patients if they would have the surgery again, with the following results: eight patients each who had the Array, AcriTwin or ReZoom would repeat the surgery; nine patients who had the Tecnis would repeat the surgery.
