Customised Artificial Lens (IOL) Treatment, Suited To Your Needs And Lifestyle!
When your vision is cloudy due to cataracts, The Vision Surgeon considers how intraocular lenses (IOLs) can shape your future. IOLs may also be appropriate for non-cataract-related conditions, including age-related presbyopia. Whatever the case, specialist refractive ophthalmologist Dr. Rylan Hayes provides a personalised solution tailored to your unique needs and preferences. Dr. Hayes is not beholden to any type of lens product or company. As a “vendor-neutral” provider, he offers a vast range of models across brands to his valued patients in Maroochydore, Queensland, the Sunshine Coast, and beyond.
What are intraocular lenses?
IOLs are artificial lenses designed to replace the natural lens when vision is compromised by conditions such as cataracts. And, whilst IOLs are often associated with cataract surgery and are most commonly used when cataracts are removed, IOLs are also placed to:
- Correct severe myopia (nearsightedness)
- Correct severe hyperopia (farsightedness)
- Treat astigmatism, compensating for an irregularly shaped cornea
- Restore focusing ability and sharp eyesight among those with presbyopia
- Minimise or eliminate one’s reliance on conventional vision correction with glasses and contact lenses
Refractive lens exchange involves removing the natural lens and replacing it with an IOL, but this treatment is performed on patients without cataracts. For instance, it may be an appropriate treatment option for patients who no longer want the hassle of glasses or contacts but are not good candidates for laser eye surgery (such as LASIK).
What types of IOLs are there?
The main types include monofocal IOLs, multifocal/trifocal IOLs, and extended depth-of-focus (EDOF) IOLs. Toric IOLs are also available to correct astigmatism, reducing or eliminating the need for glasses. While there is no single “best” IOL, there is a lens that is best or most appropriate for you. Dr. Hayes considers factors such as your eye health, prescription, and lifestyle when making recommendations. We generally balance precision with range, referring to vision across three zones: near, intermediate, and distance.
When would monofocal IOLs be most appropriate?
The “mono” in monofocal refers to “one” or “single.” Similarly, monofocal lenses are designed to provide exceptional clarity at one distance. While these precision lenses are typically set for distance vision, Dr. Hayes can set the focus to any point that suits your professional, lifestyle, and day-to-day needs. For instance, those with high accuracy needs (such as surgeons, pilots, and watchmakers) may benefit from monofocal IOLs. Glasses may still be needed when reading (at near distance) or working on the computer (at intermediate distance).
What are extended-depth-of-focus IOLs?
As their name suggests, EDOFs provide extended sharp vision over a broader range of distances. Typically, EDOF lenses are appropriate for active individuals to see clearly at intermediate to far distances. Patients appreciate that they can reduce their reliance on glasses. Normally, they may only need to wear glasses when performing tasks that require near vision, such as reading fine print. EDOFs often strike a favourable balance of range and clarity.
How do multifocal or trifocal lenses compare to other IOLs?
True to their name, multifocal IOLs provide the broadest range of vision. Unlike either monofocal or EDOF lenses, multifocal IOLs support near, intermediate, and distance vision. This is accomplished by distributing focus across multiple zones. They are an attractive option if you want to reduce your reliance on glasses as much as possible; however, there may be slight trade-offs in terms of visual quality. For instance, you may see glare or halos in low light, and there may be a minor compromise in contrast sensitivity.
