According to Dr. Nikhil Nasta of I-Sight Eye Care, EDOF IOLs are better for patients who prioritise visual comfort, night driving, and screen use, while trifocal IOLs suit patients who want maximum near vision independence. At I-Sight Eye Care, the choice depends on lifestyle, eye health, and tolerance to glare rather than one lens being universally better.



Choosing between EDOF IOL and trifocal IOL is one of the most important decisions after cataract surgery. Both are premium lenses, but they work very differently and suit very different patients.


At I-Sight Eye Care, Dr. Nikhil Nasta spends significant consultation time explaining this comparison so patients have realistic expectations and long-term satisfaction.




👁️ Understanding How These Lenses Work

How Trifocal IOLs Work

Trifocal lenses split incoming light into three distinct focal points:

  • Distance

  • Intermediate

  • Near

This provides maximum spectacle independence, but light splitting can reduce contrast and increase glare.


How EDOF IOLs Work

EDOF lenses extend the range of focus rather than splitting light.

  • Continuous distance to intermediate vision

  • Functional near vision

  • Minimal light loss

This optical difference explains most real-world performance differences.


🔍 EDOF IOL vs Trifocal IOL: Detailed Comparison

1. Quality of Vision

EDOF IOL

  • Sharper, more stable vision

  • Better contrast sensitivity

  • Clearer vision in low-light settings

Trifocal IOL

  • Good vision at all distances

  • Slight reduction in contrast

  • Some compromise in dim lighting

Dr. Nikhil Nasta notes that patients who value crisp vision often prefer EDOF lenses.


2. Night Driving and Low-Light Performance

EDOF IOL

  • Minimal glare and halos

  • Better night driving confidence

  • Safer for frequent drivers

Trifocal IOL

  • Higher chance of halos and starbursts

  • Night driving discomfort in some patients

👉 This is a key deciding factor discussed at I-Sight Eye Care.

3. Near Vision and Reading

EDOF IOL

  • Functional near vision

  • Glasses may be needed for fine print

Trifocal IOL

  • Excellent near vision

  • Greater spectacle independence

Patients who read extensively without glasses may lean toward trifocal lenses.

4. Screen Use and Office Work

EDOF IOL

  • Excellent intermediate vision

  • Ideal for laptops, mobiles, dashboards

Trifocal IOL

  • Intermediate vision present

  • Some patients experience visual fatigue

Dr. Nikhil Nasta frequently recommends EDOF IOLs for professionals and screen users.

5. Visual Side Effects

EDOF IOL

  • Low incidence of glare

  • Fewer halos

  • Less neuroadaptation stress

Trifocal IOL

  • Higher glare and halo incidence

  • Longer adaptation period

This difference is crucial for cautious or visually sensitive patients.

6. Suitability in Mild Eye Conditions

Patients with:

  • Mild dry eye

  • Early macular changes

  • Minor corneal irregularities

Often tolerate EDOF lenses better than trifocal lenses.

Dr. Nikhil Nasta considers ocular surface and retinal health carefully before recommending trifocal IOLs.

7. Adaptation Period

EDOF IOL

  • Faster adaptation

  • Vision feels more natural

Trifocal IOL

  • Longer neuroadaptation

  • Brain must learn to ignore unwanted images

🧠 Which Lens Is Better for You?

EDOF IOL May Be Better If You:

  • Drive frequently at night

  • Work long hours on screens

  • Want visual comfort over total spectacle freedom

  • Are sensitive to glare or halos

Trifocal IOL May Be Better If You:

  • Want minimal dependence on glasses

  • Read a lot of fine print

  • Accept glare risk

  • Have excellent eye health

At I-Sight Eye Care, this decision is always personalised.

👨‍⚕️ How Dr. Nikhil Nasta Chooses the Right Lens

Lens selection includes:

  • Lifestyle analysis

  • Occupation assessment

  • Night driving habits

  • Screen exposure

  • Corneal and retinal evaluation

  • Patient expectation counselling

This structured approach prevents post-surgery dissatisfaction.

🏁 Conclusion

EDOF IOL and trifocal IOL are both excellent technologies, but they serve different visual priorities. There is no single “best” lens for everyone.

Under the guidance of Dr. Nikhil Nasta at I-Sight Eye Care, patients receive personalised lens recommendations that balance clarity, comfort, and lifestyle needs.

❓ FAQs

Which is better, EDOF or trifocal IOL?

It depends on lifestyle. EDOF offers comfort, trifocal offers near vision freedom.

Are trifocal lenses risky?

They are safe but may cause glare in some patients.

Can EDOF lenses eliminate glasses completely?

Some patients may still need glasses for fine near tasks.

Which lens adapts faster?

EDOF lenses typically adapt faster.
