How does lens replacement surgery compare to wearing multifocal glasses?

If you’re struggling with switching between glasses for reading and distance, you’ve probably considered multifocal glasses—or maybe you’re already wearing them.

But there’s another option worth exploring: lens replacement surgery. It’s a long-term solution that removes your natural lens and replaces it with a clear, artificial one that can help you see at all distances.

In this blog, we’ll explain the key differences between multifocal glasses and lens replacement surgery, so you can decide which option might suit you better.

What are multifocal glasses?

Multifocal glasses have different lens powers in different parts of the lens. They allow you to see both near and far without changing glasses.

There are several types:

• Bifocals: two sections—one for distance and one for near.
• Trifocals: three sections—distance, intermediate (computer), and near.
• Progressive lenses: a smooth gradient from distance to near vision, with no visible lines.

Multifocal glasses are commonly used by people over 40 who have presbyopia, the age-related loss of near vision.

What is lens replacement surgery?

Lens replacement surgery, also known as refractive lens exchange, replaces your eye’s natural lens with a clear artificial lens, called an intraocular lens (IOL).

This lens can be chosen to give you:

• Distance vision only (monofocal)
• Distance and near vision (multifocal or trifocal)
• A broader range of clear vision (EDOF lenses)

It is the same type of procedure used in cataract surgery, but done electively to improve vision and reduce dependence on glasses.

Pros and cons: multifocal glasses vs. lens replacement surgery

Let’s break down how they compare across key areas.

1. Convenience

• Multifocal glasses: You still need to wear them all the time, and switching between pairs (e.g. computer or sunglasses) can be a hassle.
• Lens replacement: You don’t wear glasses at all or only occasionally. It’s a more permanent solution.

2. Visual clarity

• Multifocal glasses: Some people experience distortion, especially in the lower or side zones of the lenses.
• Lens replacement: You see through your eyes, not lenses on your face, which gives a more natural field of view.

3. Adaptation time

• Multifocal glasses: Some people take weeks or months to get used to the shifting focus.
• Lens replacement: There’s an adjustment period after surgery, but the vision is stable once healing is complete.

4. Cost over time

• Multifocal glasses: You’ll need new glasses every couple of years. These can be expensive, especially if you want premium coatings or frames.
• Lens replacement: One upfront cost, but no ongoing glasses expense. It also prevents future cataract surgery.

Who is lens replacement best for?

It’s ideal if you:

• Are over 45
• Don’t want to rely on glasses
• Have signs of early cataracts
• Want to see clearly at all distances
• Have been told you’re not suitable for laser eye surgery

What are the risks?

All surgery carries small risks. With lens replacement, these may include:

• Glare or halos around lights (especially with some lens types)
• Dry eyes
• Infection (very rare)

At Mitry Vision, we use high-precision diagnostics and experienced surgeons to reduce risk and support your recovery.

Final thoughts

Multifocal glasses help millions of people. But they don’t solve the underlying problem. Lens replacement surgery addresses the root cause of vision decline and offers greater independence from glasses.

It’s a more permanent solution—especially for people looking for better long-term results.
