“About 8 percent of the lenses used today are multifocals,” he says.
“The reason for this relatively low usage is a result of the typical surgeon not wanting the possibility of a lens exchange if the patient has intolerable halos or glare.
The natural lens of the eye is flexible and capable of changing shape in young persons.
The lens is held in place within the eye by fibrous strands, or zonules, which attach the outer capsule of the lens to the focusing muscle (called the ciliary muscle) that surrounds the lens.

Although they might still prefer to wear glasses for extended reading, most accommodating IOL patients experience independence from glasses for tasks such as driving, watching TV, reading menus, and using their computers and cell phones.
There are some lenses, however, that aim to bridge the gap between multifocals and monofocals and allow more vision at different distances while minimizing visual side effects.
Here’s a look at the mechanism of action and current results of these devices.
