If you are considering cataract surgery, you may have heard about intraocular lenses (IOLs). These artificial lenses replace the natural, cloudy lens in your eye to improve your vision. But did you know that there are different types of IOLs? This article will help you understand the options available.
Monofocal IOLs
Monofocal lenses have a single focus point. They are designed to provide clear vision at one distance, either close, intermediate or far. If you choose a monofocal lens set for distance vision, you’ll likely need reading glasses for close-up activities like reading.
Multifocal IOLs
Multifocal lenses offer multiple focus points. This means they allow you to see clearly at varying distances, from near to far, often reducing the need for additional glasses.
Toric IOLs
Toric lenses are specialised monofocal IOLs that correct astigmatism, a condition that blurs or distorts vision. If you have astigmatism, this type of lens could be a good option for you.
Accommodating IOLs
These lenses have a flexible design that allows them to shift focus from near to far, much like the eye’s natural lens. However, they are less common and may not fully eliminate the need for reading glasses.
EDOF (Extended Depth of Focus) IOLs
EDOF lenses provide a continuous range of vision from near to far distances. They aim to reduce the dependence on glasses for most activities but may still require reading glasses for very close work.
Summary
Choosing the right type of IOL depends on your lifestyle, vision needs, and any other eye conditions you may have. Your ophthalmologist will guide you in making the best choice for your unique situation.
