Intraocular Lens (IOL) Choice
Dr LaHood is a refractive and cataract surgery specialist with experience in biometry, astigmatism management, and the use of toric and multifocal IOL (intraocular lens) designs. He sits on advisory boards for IOL manufacturers and is involved in professional and educational discussion with his industry peers on the use of IOLs.
This expertise allows him to provide advice on IOL designs for cataract surgery and/or refractive lens exchange.
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 optimal visual outcome is an important step in your treatment. At your appointment with Ben, care is taken to explain your options and a recommendation is provided based on your eye health and 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 has experience with a wide variety of IOLs. As technology changes, new options become available. Not all lenses suit all eyes and sometimes a combination of approaches is necessary. This will be discussed in detail before your surgery.
More information about these IOL choices and what they can achieve is below.
Standard Monofocal IOL
For a standard eye with minimal astigmatism, high quality focused vision can be achieved 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 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.
Benefits and Considerations of Different IOL Types
When choosing an IOL cataract option, it’s important to understand how each lens type may suit your lifestyle, vision goals, and eye health. Here’s a quick breakdown of common intraocular lens types and what to keep in mind:
Monofocal IOLs
- Benefit: Clear vision at one fixed distance (usually far).
- Consideration: Glasses may still be needed for reading or intermediate tasks
- A common choice for those after a straightforward cataract IOL lens option.
Multifocal IOLs
- Benefit: Designed to provide vision at multiple distances
- Consideration: Some patients may notice glare or halos around lights, especially at night.
Extended Depth of Focus (EDOF) IOLs
- Benefit: Offers a more continuous range of vision compared to multifocal lenses
- Consideration: It may not provide the same level of near vision as traditional multifocals.
Toric IOLs
- Benefit: Corrects astigmatism along with cataracts
- Consideration: A good match for patients with moderate to high astigmatism
Light Adjustable Lenses (LALs)
- Benefit: Can be fine-tuned after surgery for more precise results
- Consideration: Requires specific post-op care, including avoiding UV exposure.
Choosing the right IOL lens depends on your personal vision needs, lifestyle, and medical suitability. Dr Ben LaHood can guide you through the options during your consultation.
How to Choose the Right Intraocular Lens for You
Choosing the right intraocular lens is an important step in your cataract surgery journey. With several options available, your choice should reflect your lifestyle, daily visual needs, and overall eye health. Some people prefer a straightforward solution with monofocal lenses, while others may benefit from multifocal or extended depth of focus lenses to reduce the need for glasses. If you have astigmatism, a toric cataract IOL lens may be recommended. It’s not a one-size-fits-all decision, which is why a personalised consultation with your surgeon is key. Dr Ben LaHood can guide you through the most suitable options to help you feel confident about your choice and achieve the vision outcome that works best for you.
