All multifocal intraocular lenses (IOLs) are not created equal.
Some multifocal IOLs use refractive optics and others use diffractive optics. Because the visual characteristics of the different types of optics are different, patients are likely to perceive that they have better vision with one type of lens over the other.
Depending on their own visual needs and preferences, some patients will be happier with one type of IOL or the other.
“A lot of the problems with multifocal IOLs come down to proper product selection,” said Detlev R.H. Breyer, MD. “Every doctor should understand how multifocal IOLs work or know the default modes of different IOLs. It is important to know which IOL to use for which patient.”
Dr. Breyer, partner in Premium Eyes, a private practice in Dusseldorf, Germany, compared the performance of the Lentis Comfort MF15 (Oculentis), a refractive IOL, and the Tecnis Symfony (J&J Vision Care), a diffractive IOL.
