Good visual performance, patient satisfaction shown with Tecnis ZM

SAN FRANCISCO — A diffractive lens has “excellent visual performance,” and may be useful for emmetropes and low myopes, Georges D. Baikoff, MD, said.
Dr. Baikoff spoke at the American Society of Cataract and Refractive Surgery here about the clinical results of implanting the Tecnis ZM (Advanced Medical Optics) lens in patients with hyperopia and presbyopia.
Over the course of 2 years, he implanted the lens in 15 patients whose mean age was 57 years old. The majority of patients were hyperopic, he said. The average preoperative refractive was +2.44 D, with a range from -8 D to +6.25D.
According to Dr. Baikoff, the IOL corrects presbyopia with “excellent near distance,” but patients should be warned of possible side effects, such as night halos. He said most of his patients accepted night vision problems.
Patients should also be forewarned about the possible reduction in vision at some distances, Dr. Baikoff said. He added he spends “a lot of time” before surgery with his patients, describing the procedure outcomes and technology.
“It's very important to tell the patients any kind of presbyopia surgery will be a compromise,” he said. “They gain something in near vision, and they lose it in distance.”
