An intraocular lens (IOL) is an artificial lens that's implanted during cataract surgery. The good news is that you've encountered cataracts at a time when intraocular lens technology has taken great leaps of progress. Recent advances have been so significant that new-generation lenses could allow you to see well at all distances without the help of glasses, bifocals, or reading glasses.
There are 3 primary types of lenses currently available:
- Monofocal lenses have one point of focus and can usually give you clear distance vision. While distance vision is improved, most patients still need to wear glasses for certain tasks, such as reading or working at a computer.
- Multifocal lenses are designed to replace cataracts and correct presbyopia at the same time. Their goal is to give you a full range of clear vision, near to far, and everywhere in between.
- Astigmatism-correcting lenses are for patients with existing corneal astigmatism. Similar to monofocal lenses, usually give patients quality distance vision with less dependence on glasses. Most patients will still need to wear glasses for tasks such as reading or working at a computer.
