Lens options for cataract surgery. 

Basic Monofocal Lens:

Monofocal lenses provide clear vision for a single distance (i.e. near or far) and are usually chosen to make your distance vision clearer. With a monofocal lens implant, even if you do not currently need to wear glasses for near vision activities (i.e. reading the newspaper, doing crossword puzzles, dialing a phone, or working at a computer), after surgery there is a high likelihood that you will. Depending on your degree of astigmatism, you may also need glasses for distance activities such as driving. Surgery with a monofocal IOL implant is covered by Medicare and most commercial insurance plans with the usual out of pocket expenses, such as your deductible, co-pays, and/or co-insurance. This is the basic option. 

Astigmatism correction:

Astigmatism occurs when an eye is out of round. A round eye sees better than an eye that is not round. Some astigmatism can be corrected with corneal relaxing incisions at the time of cataract surgery to make the eye rounder. Larger amounts of astigmatism may need a Toric to correct all the astigmatism. The Toric lens or relaxing incisions can usually give you good vision at distance for driving, TV, and sporting events. Glasses will be needed for reading, as well as intermediate vision. All the advanced or customizable lens implants include astigmatism correction.

Extended Depth of Focus Implant:

Extended Depth of Focus (EDOF) lenses are designed to provide a continuous range of vision with glasses-free clarity for distance, intermediate distance (computer, car dashboard, etc.), and most near vision tasks. Patients typically report needing reading glasses for very small print and extended reading, but overall enjoy a very wide range of vision with little need for correction. These lenses help patients achieve excellent intermediate and some near vision as well without loss of distance vision. Because of the way light is focused, an eye that may not be an ideal candidate for multifocal implants because of health issues such as dry eye, glaucoma, retinal irregularities may still be a good candidate for these EDOF technologies.
