What is the difference?

An intraocular lens (IOL) is a clear, plastic lens that is implanted in the eye during cataract surgery. It replaces the natural lens, which has become cloudy with age. IOLs can be monofocal, multifocal, or extended depth of focus (EDOF).

• Monofocal IOL: Has a single focal point, which is typically set for distance vision. This means that you will need to wear glasses for reading or other near activities after cataract surgery.

• Multifocal IOL: Has two or more focal points, which allows you to see clearly at both distance and near. Multifocal IOLs can sometimes cause side effects, such as glare, halos, and double vision.

• EDOF IOL: This type of multifocal IOL has a wider depth of focus than traditional multifocal IOLs. This means that it can provide better intermediate vision and reduce the need for glasses after cataract surgery. EDOF IOLs can also cause side effects, such as glare and halos.

Here are some additional things to consider when choosing your lens:

• Lifestyle: If you are active and enjoy doing things that require good near vision, such as reading, cooking, or playing sports, you may want to consider an EDOF IOL. However, if you are mostly interested in good distance vision, a monofocal IOL may be a better option.

• Budget: EDOF IOLs are typically more expensive than monofocal IOLs. If you are on a budget, a monofocal IOL may be a more affordable option.

• Risk tolerance: EDOF IOLs can cause side effects, such as glare and halos. If you are not comfortable with this risk, a monofocal IOL may be a safer option.

  
  The best type of IOL for you will depend on your individual needs and preferences. Your doctor will discuss the pros and cons of each type of IOL with you and help you decide. Ultimately, the decision is yours.
