IOL implanted after the cataract has been removed
During cataract surgery, your natural clouded lens is removed and replaced with an artifical lens implant (abreviated IOL for intraocular lens). A variety of IOL types are available, each offering different advantages. The standard IOL is monofocal (narrow range of focus, either far or near) and does not correct astigmatism. These IOLs are covered by medical insurance plans, but result in a need for glasses after surgery. For example, should you choose to have a monofocal lens for distance, you will almost certainly need reading glasses.
That being said, the image quality with standard monofocal IOLs is excellent; you will just need to use glasses for some of your activities. Toric (astigmatism correction) and multifocal (wider range of focus) IOL’s are available for an out-of-pocket expense, as they are considered premium services and are not covered by insurance.

The standard IOL, also called monofocal, has a narrow range of focus and does not correct for astigmatism. This implant type is completely covered by insurance, but most patients continue to need glasses after surgery
Multifocal IOLs
Multifocal IOLs create a broader range of focus from far to near. They work by splitting incoming light rays between far, intermediate, and near points of focus. This allows good vision at all distances, which usually reduces dependence on glasses.
Toric IOLs for Astigmatism
Toric IOLs are specially designed to correct astigmatism during cataract surgery. They are available in both monofocal (single distance) or multifocal options.
Laser Assisted Surgery
A laser system (called femtosecond laser) can be used to perform the first few steps of the cataract surgery, including breaking up your cataract before it is removed. It can also be used to correct for a low amount of astigmatism. Laser assisted surgery is availabe for an out-of-pocket fee and is not a service covered by insurance companies. When laser is used, the removal of your cataract will have to be finished manually by your surgeon. The laser is not necessary in every case, and some eyes would not be good candidates. Thus, you and your surgeon will decide jointly if the laser is a good option.
