Cataract surgery not only removes the cloudy lens but also replaces it with an artificial lens. The choice of lens depends on the patient’s vision needs, lifestyle, and job profile. Vision is usually categorized into three types – distant vision (like driving or watching TV), intermediate vision (like working on a computer or cooking), and near vision (like reading or using a mobile phone).

Monofocal Lens – This is the most common type of lens. It corrects vision for one distance, usually distant vision. Patients may still need glasses for near and intermediate tasks.

EDOF (Extended Depth of Focus) Lens – This lens provides clear distant and intermediate vision, which is helpful for activities like driving or computer work. However, for near tasks such as reading, glasses are usually needed.

Multifocal Lens – This lens corrects all three types of vision: distant, intermediate, and near. Patients generally don’t need glasses after surgery. It is especially beneficial for people above 40 years who want more freedom from spectacles.

Toric Lens – This lens is specially designed for patients with astigmatism. It provides clearer vision by correcting irregular curvature of the cornea.

In the end, the lens choice depends on the patient’s lifestyle, preferences, and the type of work they do. A detailed discussion with the doctor helps in choosing the most suitable option.
