Two-year data promising for dual-optic accommodating IOL

The newer generation of a dual-optic accommodating IOL (Synchrony, Visiogen) is easy to implant, centers well, provides good distance visual acuity, and demonstrates good safety in terms of potential posterior capsule opacification development, according to H. Burkhard Dick, MD.

Dr. Dick, professor of ophthalmology, Johannes-Gutenberg University, Mainz, Germany, discussed 2-year data related to hisexperience of implanting 30 of the silicone lenses, which have a high diopter anterior optic and a minus power posterioroptic, in a prospective trial of otherwise healthy eyes.

"The most important thing was preoperative counseling and biometrics," he said. "This included lens thickness evaluation."

Focus curve measurement showed that the IOL demonstrated accommodative amplitude in every patient, even after 2 years, Dr.Dick said. The mean was 1.5 to 1.75 D. Also, he said, no Nd:YAG capsulotomies have been required.

"All patients were very satisfied with the lens, and in terms of functionality, it was quite satisfying. Also, reading speedwas very sufficient," Dr. Dick said.

Because of its relatively large size, the IOL requires a relatively large incision for implantation, he said.

"My standard incision size is about 2.75 mm, but this is a thickness [where] you can't implant this lens," Dr. Dick said.

The lens has earned a CE Mark in Europe, he added.
