What are the disadvantages of multifocal intraocular lenses?

The main disadvantages of multifocal IOL implantation include poor visual quality, eye discomfort, eye infection, etc.

1. Poor visual quality

Although multifocal IOL can provide near and far focus, it does not provide perfect vision like natural lens, which may lead to decreased visual quality.

2. Eye discomfort

After multifocal IOL implantation, some patients may feel eye discomfort, such as dry eyes, congestion, foreign body sensation or mild pain.

3. Eye infection

Patients undergoing multifocal IOL implantation are at risk of developing eye infection. Postoperative infection may lead to serious complications such as keratitis, iridocyclitis, etc.
