Gangnam Station Ophthalmology | Is a continuous-focus lens better than a multifocal lens for cataracts?

Hello, this is Gangnam Smile Eye Clinic 😊💙

If you are considering cataract surgery,

you are likely concerned about choosing an intraocular lens.

Recently, continuous-focus lenses (EDOF),

which surpass traditional multifocal lenses, are gaining attention.

Today, we will explain in detail the characteristics of ‘cataract continuous-focus lenses’,

suitable patient types, and important points when choosing a lens, as informed by Gangnam Station Ophthalmology.

What is a continuous-focus lens (EDOF)?

A continuous-focus lens, as its name suggests,

is an intraocular lens where the ‘focus is continuously connected’.

While traditional multifocal lenses focus on two points, distant and near,

continuous-focus lenses provide a more naturally connected field of vision

from intermediate to distant ranges.

This means it's possible to secure a smooth and continuous field of vision without focus interruption,

making it advantageous for seeing more naturally in daily life.

Another significant advantage is the relatively reduced glare and night glare.

Types of Representative Continuous-Focus Lenses

The main continuous-focus lenses currently used domestically and internationally include:

• Symbios
  The latest EDOF lens that seeks harmony between near, intermediate, and distant vision.
• Vivity
  Emphasizes clarity of vision and securing a natural field of vision.
• Synergy
  Combines continuous-focus characteristics with optical technology to cover full-range vision.
• PanOptix
  A product from Alcon, USA, widely used in all ophthalmology clinics,
  providing high-quality vision with a wide range of focus.
• FineVision
  Complements the limitations of existing multifocal lenses and improves intermediate vision quality.

Who is a cataract continuous-focus lens suitable for?

Continuous-focus lenses are not suitable for everyone.

They can be particularly effective in the following cases:

• If you frequently view at intermediate distances
  Such as office work, driving, cooking, playing musical instruments, etc.,
  where there is a lot of activity at intermediate distances.
• If you have retinal optic nerve disease
  In cases of underlying eye diseases such as glaucoma, macular degeneration, or diabetic retinopathy,
  traditional multifocal lenses can cause discomfort due to side effects like glare.
  In contrast, continuous-focus lenses are effective in improving vision quality with less reduction in contrast sensitivity.

More important than lens selection is the ‘skill of the medical team’

While cataract continuous-focus lenses come in various types and functions,

their selection is equally challenging and requires professional judgment.

Precisely selecting the most suitable lens based on the patient's eye condition, lifestyle, and vision goals is key.

Such accurate judgment stems from the medical team's skill, based on extensive clinical experience and state-of-the-art equipment.

Simply because a lens is good does not guarantee a good outcome.
