Advanced multifocal IOLs allow for better vision, fast adaptation, no photic phenomena
Ljubljana, SLOVENIA — Advances in multifocal IOL technology allow for more natural vision with considerable improvement at intermediate distances, no photic phenomena and the possibility to combine different adds for increased depth of focus, according to one surgeon.
“The tendency is to make reading distance more physiological and to meet the needs of the increasing number of patients who use computers, iPads and iPhones. Manufacturers are also going towards reduction in the number of rings to avoid halos, glare and other photic phenomena,” Ante Barisic, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
In a study, the new one-piece low-add Tecnis models (Abbott Medical Optics) were used in different groups of patients, according to age and lifestyle. In two groups, bilateral implantation of the Tecnis ZLB00 with +3.25 D near add or the Tecnis ZKB00 with +2.75 D near add was performed. Spectacle independence was obtained at all distances, with a small sacrifice of intermediate vision in the first group and near vision in the second group.
“In this group, we were aiming for younger patients who used the computer frequently,” Barisic said.
A combination of the two lenses was used in a third group, leading to good vision at all distances.
“None of the patients had complaints, in spite of the two different lenses in the two eyes. Old mix-and-match combined different refractive and diffractive technologies and required adaptation to two different images. Here we use the same technology, patients easily adapt, and phenomena are a thing of the past,” Barisic said.
