Can Night Vision Improve After Cataract Surgery?

Yazar: Op. Dr. Gökay Günay

Reduced night vision is one of the complaints most frequently reported by people with cataracts.

Some people can manage their daily activities during the day but notice a clear reduction in quality of vision when driving at night or in low-light environments.

For this reason, many people planning cataract surgery ask:

“Will my night vision improve after surgery?”

Why Does Cataract Reduce Night Vision?

A cataract develops when the eye’s natural lens gradually loses its transparency.

This may affect not only visual acuity, but also quality of vision.

In particular:

  • Glare from headlights
  • Light scatter
  • Reduced contrast
  • Difficulty driving at night

These symptoms may occur even in the early stages of cataract.

For some people, reduced night vision may be more troublesome than blurred vision.

Can Night Vision Improve After Cataract Surgery?

For many patients, yes.

When the cataractous lens is removed and replaced with a clear intraocular lens, the quality of light entering the eye may improve.

For this reason, many people report after surgery:

  • Clearer images
  • More vivid colours
  • Improved contrast perception
  • Greater comfort when driving at night

These improvements may be noticed.

Does Every Patient Have the Same Result?

No.

Night vision does not depend on cataract alone.

Other factors include:

  • Retinal health
  • Corneal structure
  • Dry eye
  • The type of intraocular lens used

These factors may also affect quality of vision.

For this reason, outcomes may vary from person to person.

Can Lens Choice Affect Night Vision?

Yes.

Monofocal, EDOF and multifocal lenses have different optical characteristics.

For this reason, lifestyle and night-vision expectations should be assessed before surgery.

This is particularly important when planning treatment for people who frequently drive at night.

Conclusion

Cataract surgery may improve not only visual acuity, but also night vision and overall quality of vision in many patients.

However, achieving the most appropriate result requires not only removing the cataract, but also creating a treatment plan suited to the person’s lifestyle and visual expectations.
