Question 1

What is an EDOF lens for cataract surgery?

Accepted Answer

An EDOF (Extended Depth of Focus) lens is a premium intraocular lens used in cataract surgery. Rather than focusing at a single point like a standard monofocal lens, an EDOF lens elongates the focal range to provide a continuous, seamless zone of clear vision from distance through to intermediate (computer distance). Most patients can drive, use a computer and watch television without glasses.

Question 2

How is an EDOF lens different from a multifocal IOL?

Accepted Answer

EDOF lenses provide a continuous elongated focal range, while multifocal lenses create distinct separate focal zones for near, intermediate and distance. The key practical difference is that EDOF lenses produce significantly fewer halos and glare at night compared to multifocal lenses, while still reducing glasses dependence for most tasks. Multifocal lenses offer greater independence from reading glasses but with a higher rate of optical side effects.

Question 3

Will I still need reading glasses with an EDOF lens?

Accepted Answer

Most patients with EDOF lenses do not need glasses for distance or intermediate tasks (driving, computers, television). Some patients still require reading glasses for fine print in low-light conditions, such as reading a menu in a restaurant. The need for reading glasses varies between individuals and between different EDOF platforms.

Question 4

Do EDOF lenses cause halos or glare?

Accepted Answer

EDOF lenses produce significantly lower rates of halos and glare than multifocal lenses, making them a popular choice for patients who are concerned about night vision or drive frequently at night. Some mild halos may be present initially but typically improve with neuroadaptation. The degree of optical side effects varies between EDOF platforms.

Question 5

Which EDOF lenses are available in Australia?

Accepted Answer

Several well-established EDOF platforms are available in Australia, including the Tecnis Symfony (Johnson & Johnson), Alcon Vivity, and HOYA Vivinex iSert XY1C. Each has slightly different optical characteristics, focusing range and side effect profiles. Dr MacIntyre will recommend the most appropriate platform based on your individual eye measurements and visual priorities.
