Intra-ocular Lens Implant after Cataract Surgery

After cataract surgery you will need to have an Intra-ocular Lens Implant (IOL) to allow you to focus and see clearly.  There is a variety of lens implants to choose from to suit your lifestyle requirements.  You can discuss with your ophthalmologist (eye surgeon) which lens implant is most suitable for you.

Monofocal IOL Plain

Monofocal IOL allows you to see a single zone of clear focus.  You may choose to have the IOLs in both eyes to see distant vision in which case, you will need reading glasses for near vision activities such as reading, sewing or looking at your phone. 

If you opt to have 1 monofocal IOL to see distant vision and 1 monofocal IOL (in the other eye) to see near vision, then you will have mono-vision where 1 eye sees distant vision and 1 eye sees near vision.  This allows you to be spectacle free some of the time but not every patient is able to tolerate this option.

Monofocal IOL Toric

Monofocal Toric IOL allows a patient to see a single zone of clear vision similar to plain Monofocal IOL with the extra benefit of also treating high astigmatism.  This improves the clarity of the vision for the distant vision by reducing the astigmatism.

Bifocal / EDOF IOL

Bifocal IOL (also known as ‘extended depth of focus’ lens implants) is designed to create a single-elongated focal point to enhance the depth-of-focus to allow good distant and intermediate (computer) vision. 

Multifocal / Trifocal IOL Plain

Multifocal IOL is designed to provide patients with a larger range of vision at various distances such as far, intermediate (computer) and near vision.

Multifocal Toric IOL allows a patient to see en extended range of clear vision similar to plain Multifocal IOL with the extra benefit of also treating high astigmatism.  This improves the clarity of the vision by reducing the astigmatism.

What are the benefits of Multifocal or EDOF IOL implants?

Multifocal or ‘extended depth of focus’ IOLs allow the patient to have the opportunity to become less dependent upon glasses after cataract surgery.  Some patients can become glasses free after cataract surgery but this varies between individuals as everyone’s eye is different.  There are some side effects for multifocal IOL and they include glare, haloes, loss of light contrast and overlapping images.  For most patients, these are only minor symptoms and they are usually happy with the vision after their surgery.

Discuss the IOL options with your Eye Doctor
