Artificial Lens Implant
What are artificial lens implants?
An intraocular lens (IOL) is a tiny, artificial lens that is implanted into the eye. It is often used to replace a person’s natural lens when this is removed during cataract surgery or refractive lens surgery. New IOL options are being introduced each year. At Circle Health, we offer the latest types of these intraocular lenses in a range of customised styles and strengths.
A monofocal lens is the most common type of artificial lens implant. It has one focusing point that can be set to correct your vision for distance – intermediate or near distance– but not all at the same time. Most people have monofocal lenses so that they can see clearly at a distance, and they use reading glasses for close work.
Multifocal lens implants are designed to help you see near, far and in between, without glasses or contact lenses. These types of lens implants reduce your dependence on glasses by giving you clear vision for more than one set distance.
A multifocal lens has different zones set at different powers. These IOLs provide both distance and near focus at the same time. They are designed so that your brain learns to select the right focus automatically.
Toric lens implants can be used to correct astigmatism, depending on how your cornea is shaped. Astigmatism is caused by an uneven curve in your cornea or lens. The toric lens is designed to correct this error.
Sometimes patients undergoing lens implant surgery or cataract surgery will receive a monofocal lens with a different power in each eye so that they don’t have to use glasses for most daily activities. The dominant eye is generally corrected for distance, and the other eye is corrected for near. Many people successfully use monovision with contact lenses. Successful monovision requires surgery to both eyes.
How can I see a doctor?
At Circle Health, we can arrange a private clinical appointment for you to visit a leading consultant ophthalmologist who specialises in intraocular lens implants. They can assess your condition, and advise you about the specific artificial lens that would be most appropriate for you.
