When it comes to addressing vision impairment through cataract surgery, you’ll likely face a decision between which lens implant is best for you. Each option offers distinct benefits and considerations, catering to individual needs and lifestyle preferences
In this article, I’ll answer your questions about multifocal and advanced monofocal lens implants.
What is a Multifocal Lens Implant?
Multifocal lens implants represent a significant advancement in vision correction, designed to provide clear vision at various distances. Unlike a standard monofocal lens, which typically corrects vision at a single focal point, multifocal implants incorporate advanced technology to accommodate both near and far vision.
How do Multifocal Lenses Work?
These lenses work by distributing incoming light across multiple focal points, allowing individuals to see objects clearly at various distances without the need for glasses. This versatility is particularly advantageous for individuals with active lifestyles or those who desire freedom from dependency on corrective eyewear.
Which Multifocal Lenses do I use?
The only multifocal lens I use is the Rayner Trifocal, particularly in instances where the patient is determined not to wear glasses for reading.
Are There any Disadvantages to Multifocal Lenses?
Some multifocal patients can experience minor impairments after surgery. These can include:
Halo or glare: around 5-10% of patients may experience halos or glare when viewing lights at night, though many adapt to this over time.
Contrast struggle: some people may find it challenging to perceive contrast, especially when reading in dim lighting conditions. However, reading in dim light is generally discouraged for eye health regardless of lens type.
Need for reading glasses and/or extra light: some patients may require reading glasses and/or extra light for viewing fine print.
Enhanced Monofocal Lens Implants
What is an Enhanced Monofocal Lens Implant?
An enhanced monofocal lens represents a refinement of traditional monofocal lens technology, offering improved visual outcomes for patients undergoing cataract surgery.
While standard monofocal lenses are set to focus at a single distance, typically either near or far, enhanced monofocal lenses incorporate advanced optical design to provide better visual clarity across a broader range of distances.
Enhanced monofocal lenses aren’t typically as versatile as multifocal lenses, but they’re not associated with the minor visual issues (like halos) caused by multifocals.
Will I Still Need Glasses With Enhanced Monofocal Lenses?
There’s still a good chance you’ll need glasses for reading or other short range activities, but you’ll likely still have much more visual freedom compared to those with standard monofocal lenses. The benefits of enhanced monofocal lenses are most apparent when you’re doing mid-range activities, like computer work.
What’s an EDOF?
EDOF stands for Extended Depth of Focus. It’s a type of enhanced monofocal lens.
Which Enhanced Monofocal Lenses do you use?
I use the Alcon Clareon Vivity and Rayner EMV lens implants.
The Clareon Vivity is a next-generation EDOF (Extended Depth of Focus) lens, providing enhanced visual acuity across a range of distances.
The Rayner EMV (Extended Macular Vision) lens offers an improved range of focus over a standard monofocal lens.
Both implants aim to enhance overall visual quality and reduce reliance on corrective eyewear, offering patients greater freedom and comfort in daily activities.
Are Lens Implants Safe?
Lens implants are considered a safe and fast procedure, but I’ll make sure you understand all of the potential complications that could arise prior to any treatment.
Who are Lens Implants for?
Lens implants are used primarily for cataract patients, but they can also be used to control and correct Astigmatism and Presbyopia (a condition associated with ageing, whereby the natural crystalline lens of the eye progressively loses its ability to focus).
