1. Monofocal IOLs:  Monofocal IOLs are the most common type. They have a single focus point, typically set for distance vision. Patients may still need glasses for reading or close-up tasks.

2. Multifocal IOLs: Multifocal IOLs are designed to provide multiple focal points, allowing patients to see clearly at different distances, including near, intermediate, and far. These lenses can reduce the need for glasses after cataract surgery.

3. Extended Depth of Focus (EDOF) IOLs: EDOF IOLs aim to provide an extended range of clear vision for distance and intermediate tasks, reducing the need for reading glasses.

4. Toric IOLs: Toric IOLs are specifically for patients with astigmatism. They have different powers in different meridians to correct the irregular shape of the cornea and improve astigmatism.
