Multifocal IOLs

Monofocal IOLs provide clear vision at one focal distance, typically for either near or distance vision. In contrast, multifocal IOLs have multiple focal points built into the lens, enabling patients to see clearly at near, intermediate, and far distances. This design reduces or eliminates the need for glasses or contacts post-surgery, offering a broader range of vision.

Some patients may experience temporary visual disturbances such as glare, halos around lights, or reduced contrast sensitivity, particularly at night. These effects usually improve over time as the brain adapts to the multifocal lens. In general, most patients adjust within a few weeks, but it’s important to discuss potential side effects with your ophthalmologist beforehand.

Multifocal IOLs are meant for long-term use and are made from durable, biocompatible materials. Once implanted, they typically last a lifetime without the need for replacement. However, over time, changes in your eye health or vision may occur, especially as you age.

Yes, certain multifocal IOLs are available with built-in correction for astigmatism. These lenses are called toric multifocal IOLs. They can address both presbyopia (age-related near-vision loss) and astigmatism simultaneously, providing clear, well-rounded vision. If you have astigmatism, Dr. Hu will determine the best lens option during your consultation.

Most patients who receive multifocal IOLs experience reduced or complete elimination of the need for reading glasses. The lens’s ability to focus at various distances means you can see clearly up close, at intermediate distances, and far away without glasses. However, in some cases, particularly for patients with extremely high prescriptions or significant visual demands, reading glasses may still be required occasionally for very small print or detailed work.
