As we age, cataracts are a natural change in the eyes, much like an inevitable stage of life. Currently, cataracts cannot be reversed with medication or other methods; surgery is the only effective treatment. However, with various types of intraocular lenses available on the market, how should one choose the right type?

Common types of intraocular lenses currently available mainly include the following:

Monofocal IOLs
‧ Provide clear vision at a single focal point, usually set for distance.
‧ After surgery, distance vision is clear, but glasses are typically needed for near-vision activities such as reading or using a mobile phone.

Trifocal/Multifocal IOLs
‧ Provide vision at three focal points—distance, intermediate, and near—covering most visual needs in daily life.
‧ Can reduce dependence on glasses, though some people may experience halos or glare at night.

Extended Depth of Focus (EDOF) IOLs
‧ Provide continuous clear vision from far to intermediate distances.
‧ Suitable for individuals who frequently engage in intermediate-distance activities (such as using a computer or cooking). Night vision quality is generally better than with multifocal lenses.

Light Adjustable Lens (LAL)
‧ Within a certain period after surgery, doctors can adjust the lens power non-invasively using UV light to fine-tune vision.
‧ Offers a higher degree of personalized adjustment for visual needs.

Each type of intraocular lens has its own characteristics. When making a choice, consider your lifestyle, visual needs, and budget, and have a detailed discussion with an ophthalmologist to make the best decision for yourself.
