Cataract Surgery and Different Types of IOLs: What You Need to Know

What Is Cataract Surgery?

Cataract surgery is a common eye procedure. Doctors remove the cloudy lens from your eye and replace it with a clear artificial lens. This new lens is called an intraocular lens, or IOL. Many people need cataract surgery as they get older. In fact, it is one of the safest and most effective surgeries worldwide. According to the World Health Organization, cataracts are a leading cause of vision loss. However, surgery can restore clear sight for most patients.

Why Is Cataract Surgery Needed?

Cataracts make the lens of your eye cloudy. As a result, you may notice blurry vision, glare, or trouble seeing at night. Sometimes, colors may look faded. Over time, cataracts can make daily tasks hard. For example, you might struggle to read, drive, or recognize faces. When glasses or brighter lights no longer help, cataract surgery is often the best choice. Early treatment can improve your quality of life and help prevent accidents or falls.

Overview of Intraocular Lenses (IOLs)

During cataract surgery, your doctor removes the cloudy lens. Then, they place a new, clear lens inside your eye. This artificial lens is called an intraocular lens, or IOL. There are several types of IOLs. Each type offers different benefits. Your eye doctor will help you choose the best one for your needs. The right IOL can help you see better at different distances and reduce your need for glasses.

Types of IOLs: Pros and Cons

There are many types of IOLs available today. Each type has its own features. Let’s look at the most common options:

Monofocal IOLs: These lenses focus at one distance, either near or far. Most people choose distance vision and use reading glasses for close work.

Pros: Clear vision at one distance, affordable, fewer side effects.

Cons: You may still need glasses for some tasks.

Multifocal IOLs: These lenses have zones for both near and far vision. They can reduce your need for glasses.

Cons: Some people notice glare or halos, especially at night.

Toric IOLs: These are designed for people with astigmatism. They help correct blurry or distorted vision caused by an uneven cornea.

Cons: Results may vary, and some people still need glasses.

How to Choose the Right IOL

Think about your daily activities

Consider if you want to reduce your need for glasses

Discuss your eye health and any other conditions with your doctor
