Types of Cataract Lenses

Cataract surgery involves removing a clouded lens and replacing it with an artificial intraocular lens to improve your vision. It is important to understand that not all cataract lenses are the same. Some can help you see near or far even better. Choosing the right cataract lens for you can be confusing. Understanding the various lens options is essential before making your cataract lens choice. Your eye health, prescription, and level of corneal astigmatism are important in helping you decide which lenses will work best for you.

Cataract Lens Options

When it comes to cataract surgery, choosing the appropriate intraocular lens (IOL) is crucial for achieving optimal visual outcomes. At SightMD, we provide a wide range of cataract lenses designed to cater to the unique needs of our patients. Below, we present an overview of the various types of lenses available:

Monofocal Cataract Lenses

Multifocal lenses are specifically designed to offer clear vision at various distances, minimizing the need for glasses during near and intermediate activities. These lenses utilize a combination of focal points to improve vision across a wide range of distances.

However, some patients may experience halos or glare, particularly in low-light conditions. Additionally, this lens option may not be suitable for individuals with certain eye conditions.

Multifocal Cataract Lenses

Multifocal lenses are specifically designed to offer clear vision at various distances, minimizing the need for glasses during near and intermediate activities. These lenses utilize a combination of focal points to improve vision across a wide range of distances.

However, some patients may experience halos or glare, particularly in low-light conditions. Additionally, this lens option may not be suitable for individuals with certain eye conditions.

Toric Cataract Lenses

Toric lenses are a special type of lens made to fix astigmatism. Astigmatism is a common problem caused by a misshaped cornea, which leads to blurry vision. These lenses effectively address both cataracts and astigmatism simultaneously.

By correcting astigmatism, toric lenses help reduce a patient’s dependence on glasses, enhancing overall visual clarity. However, it’s important to note that they may not completely eliminate the need for glasses, particularly for reading. Additionally, toric lenses generally come at a higher cost compared to standard monofocal lenses.

Accommodating Lenses

Accommodating lenses are engineered to replicate the natural flexibility of the eye’s crystalline lens. They dynamically adjust focus, enabling patients to see clearly at various distances without the need for glasses.
Patients using this type of lens often report fewer visual problems than those with multifocal lenses. They also notice better depth of focus.

It’s important to know that accommodating lenses may cost more than monofocal lenses and the results can vary for each person.

Extended Depth of Focus Lenses

Extended Depth of Focus (EDOF) lenses provide a smooth range of clear vision while improving your ability to see things at an intermediate distance. They significantly reduce the reliance on glasses for various tasks and facilitate a smooth transition between different focal points. Additionally, EDOF lenses generally produce fewer visual disturbances, such as halos and glare, when compared to multifocal lenses.

Light Adjustable Lenses

Light Adjustable Lenses (LALs) signify a significant advancement in personalized vision correction. After implantation, doctors can adjust these lenses with a special UV light treatment. This helps fine-tune the visual outcome. This level of customization guarantees that the final vision correction is as accurate as possible, delivering an unparalleled degree of clarity and satisfaction.

Choosing a Cataract Surgery Lens

The primary decision is the type of vision you want to have after surgery:

  • Excellent Distance Vision – but requires reading glasses  
  • Excellent Reading Vision – but requires distance glasses  
  • Excellent Distance Vision along with Computer Vision  
  • Excellent Distance, Computer, and Reading Vision  
  • Monovision – distance vision in one eye and reading vision in the other. Many patients find it hard to adjust to monovision as it can limit depth perception and raise the risk of falls.

Cost of Cataract Lenses

The cost of cataract lenses varies depending on the type selected. On average, Toric lenses for cataract surgery tend to be more expensive than multifocal cataract lenses. Monofocal cataract lenses are generally more affordable, while toric and multifocal lenses fall on the higher end of the price spectrum.

It’s important to note that insurance coverage for cataract lenses is not universal. Medicare and most insurance companies usually pay for monofocal lenses. These lenses have been used for decades and are one of the more popular choices.

Other alternatives, such as multifocal, EDOF (Extended Depth of Focus), and accommodative cataract lenses, can help reduce the reliance on glasses or contact lenses. However, the ability to read and perform various tasks without corrective eyewear can differ from person to person. These cataract lenses are often called “premium” lenses. They offer a wider range of vision than monofocal lenses. However, it’s important to note that they are often not covered by insurance.

How to pick a Cataract Lens

However, it’s important to note that not all cataract lenses are identical. Choosing the right cataract lenses can be difficult. Our doctors will help guide you to an informed decision that best fits your budget and your lifestyle.

  • Does your lifestyle rely on near vision? – One option is to choose monofocal cataract lenses for seeing things up close. You can use glasses for distance tasks, like watching TV and driving. If you often use digital devices or are nearsighted, this could be the perfect choice for you. If you find eyeglasses uncomfortable and want to avoid them, consider monofocal lenses. One lens can be for distance vision, and the other can be for near vision. However, this approach may not be suitable for everyone. Many people find that their brains can adjust and combine the information from both eyes. This helps them see well at all distances. Before cataract surgery, you can try monovision contact lenses for a while. This will help you see if monovision works for you.
  • Do you frequently drive at night? – If night driving is a priority for you, it may be wise to avoid multifocal or EDOF lenses. With these lenses you might experience side effects such as glare, halos around lights, and less contrast. This can lead to dull vision, especially at night or in low light. Most people adjust to these effects. However, those who often drive at night may prefer monofocal cataract lenses.
  • Do you have moderate to high astigmatism? – Astigmatism happens when the cornea is shaped like a football instead of a basketball causing one curve to be longer than the other. This irregular shape distorts the vision of both near and distant objects. Individuals with moderate to high astigmatism often find greater satisfaction with toric cataract lenses. Another option your doctor might suggest is a procedure called limbal relaxing incisions (LRIs). This procedure is often used to help with astigmatism and can be performed either during cataract surgery or as a separate treatment. It’s important to note that insurance may not fully cover the costs of toric lenses or LRIs.
  • Do you have other eye conditions? – Multifocal and Extended Depth of Focus (EDOF) lenses are usually not recommended for people with vision loss. This includes those with glaucoma, macular degeneration, or other eye problems. These cataract lenses let in less light which can make vision problems worse for people with existing damage. If reducing the need for glasses is important to you and you have eye damage, monovision might be a better choice.
