What Happens to My Eye After Cataract Surgery: Understanding Artificial Lenses

Cataract surgery involves the removal of the cloudy lens affecting your vision. But what happens next? This article explains how an artificial lens replaces your natural lens to help you see clearly again.

Why Replace the Lens?

When the cloudy lens is removed during cataract surgery, it needs to be replaced to help you focus and see clearly. An artificial lens, known as an intraocular lens (IOL), serves this purpose. These lenses are clear, which means once they are in, the cloudy vision you experienced should go away.

What Is an Intraocular Lens (IOL)?

An intraocular lens (IOL) is a clear, plastic lens that becomes a permanent part of your eye. It is custom-fitted to your eye’s specifications and helps restore your vision.

Types of Intraocular Lenses

There are different types of IOLs, each designed for different visual needs:

  • Monofocal IOLs: These lenses focus on one distance—either near, intermediate or far. People with monofocal IOLs might still need spectacles to see clearly in certain conditions. For example, a monofocal lens set for distance vision will likely require you to use reading glasses for close-up tasks.
  • Multifocal IOLs: These lenses allow you to focus on objects at varying distances.

Is the Procedure Risky?

The procedure to insert an IOL is generally considered low-risk. It is performed under local anaesthesia, and you shouldn’t feel pain during the operation.

Will I Feel the Lens?

No, you won’t feel the artificial lens once it’s in place. It becomes a part of your eye, and you’ll likely forget it’s even there.

Taking Care After Surgery

Your eye may feel sensitive for a few days after the operation. Following your eye doctor’s (ophthalmologist’s) instructions can help speed up the healing process.


If you have cataract surgery, an artificial lens is inserted to replace the cloudy lens that was removed. This lens helps you regain clear vision and improves your quality of life.
