Cataract surgery: What type of lens replacement is right for me?

What is an intraocular lens implant?

An intraocular lens implant, also called an IOL, is a clear artificial lens made of a plastic-like material that replaces the natural cataract-affected lens inside the eye during the cataract surgery. It lasts a lifetime and can’t be seen or felt after the surgery. Some of the IOLs also help to correct astigmatism and reduce reliance on glasses for certain types of tasks after the surgery.

What are the main types of intraocular replacement lenses available?

• Standard Monofocal implants: these are widely available lenses. They provide good distance vision, and glasses are needed for seeing at arm’s length and closer.

• Premium Monofocal-Plus implants: a premium lens, similar to the above but provide a better range of distance vision.

• Extended Depth of Focus (EDOF) implants: premium lenses that provide good distance and intermediate (at arm’s length) vision sufficient for most daily visual activities including shopping, cooking and desktop computer work, although reading glasses may still be needed for close work and reading small print.

• Trifocal (also called multifocal) implants: premium lenses that can help to achieve a full range of glasses-free distance, middle and near vision without the need for glasses.

• Toric implants: premium lenses which help to correct astigmatism at the time of surgery and can be combined with any of the lenses mentioned above.

In some cases, combinations of lens implants are required to address specific eye health and lifestyle needs, and this is usually discussed with the consultant during your initial consultation. Not all lens options are suitable for every patient, as the most appropriate choice depends on your individual eye health and any existing conditions. Your surgeon will discuss the best option for you, along with any potential side effects, at your consultation.

What do I need to consider when choosing a replacement lens for my cataract surgery?

Your consultant will provide individual advice based on your eye health, lifestyle and any specific needs. One of the key considerations is whether you would be comfortable wearing glasses for some activities or aim to be completely glasses-free after your cataract surgery. It may be helpful to start thinking about this before your consultation, so you can be offered the best solution for you.

What is the cost of intraocular replacement lenses?

Standard monofocal lenses are generally the least expensive option because they correct vision at one focal point (usually distance). They are typically included in NHS cataract surgery and also into the fixed package price for cataract treatment at Moorfields Private.

There is a wide variety of premium lenses, including multifocal or varifocal lenses, on the market which cost more because they involve more advanced optical engineering to provide a broader range of vision and reduce dependence on glasses after surgery. Their cost varies depending on the manufacturer, brand, and design features.

If you require astigmatism correction, toric lenses can be combined with both monofocal and premium lens options. Choosing a toric implant will usually increase the overall cost of treatment.

Your consultant will discuss the most suitable type of intraocular lenses for your lifestyle and visual goals with you at your initial consultation. The cost of intraocular replacement lenses is included into the personalised treatment plan.
