IOL Choices

Dr LaHood is a refractive and cataract surgery specialist

He is well known for both his research and practice relating to biometry, astigmatism management and the use of toric and multifocal IOL (intraocular lens) designs.

His expertise in this area is widely acknowledged by his peers. He sits on advisory boards for IOL manufacturers and frequently is an invited lecturer globally to discuss the use of various IOLs to educate and teach his peer group.

As a patient this might be above your need of ophthalmic understanding, but for you it means that you are in good hands! Ben’s knowledge, experience and expertise ensures that he is able to provide you the best IOL designs to achieve optimal visual outcomes for your cataract surgery and/or refractive lens exchange.

If you are interested, more information is provided below on both the surgery itself, and the different IOL solutions currently available. Ben will discuss in detail the options below at your consultation prior to your surgery and provide you the opportunity to ask any questions and address any concerns you may have.


About the surgery

During cataract and refractive lens exchange surgery, a new intraocular lens (IOL) is implanted in your eye to provide you with the best possible visual acuity.

Choosing the right lens for your best visual outcome is an important step in your treatment. At your appointment with Ben, much care and plenty of time is spent explaining your options and a recommendation is provided based on your visual goals. You will also be informed of expected visual outcomes and what to expect during your surgery and recovery.


Newer IOL types and combinations

Dr LaHood is at the forefront of IOL technology and has access to and experience with a wide variety of IOLs. As technology changes, new options become available, and you will be offered the best options. Not all lenses suit all eyes and so sometimes a combination of approaches is necessary. This will be discussed in detail before your surgery.

More information about these choices and what they can achieve is below.

Standard Monofocal IOL

For a standard eye with minimal astigmatism, you can achieve high quality focused vision with a standard monofocal IOL. The modern designs of these lens types give excellent vision quality. The eye will have one focus, either for distance or near vision, and so a decision will have to be made about the overall plan for both eyes. See presbyopia solutions for more on this.

Extended Depth of Focus (EDOF) IOL

This type of lens will give a range of vision. Usually, they are used to give distance and intermediate vision so that you could drive as well as see the computer without glasses but prolonged reading would require reading glasses. There are different styles of these for different goals.

Trifocal IOL

The trifocal IOL gives three focal points. If you want everything for your vision, this may be the best option for you. It gives good distance, intermediate and near vision meaning that you should not need glasses for any task including reading. The trade-off is that you will initially experience glare and halos, especially at night, that will reduce over the first month. Maximum benefit is gained with this IOL in both eyes but one eye can be implanted as a mixture. This is explained to you in more detail at your consultation.

Toric IOL

If your eye has any astigmatism, it is likely you will need a toric IOL. Astigmatism is where one axis of your cornea is steeper than another. Think of a rugby ball compared to a soccer ball. Glasses correct this to give you crisp focused vision and a toric IOL will do the same. These IOLs are fantastic and provide excellent visual results but must be implanted and planned very precisely to maximise visual outcomes. Dr LaHood will be able to tell you whether a toric IOL is needed in your case and recommend a plan of action. A toric IOL option of a trifocal IOL is often needed to give best results, again which can be further explained at your appointment.
