What Is Cataract Surgery?
A cataract develops when the eye’s natural lens becomes cloudy, causing blurry and dim vision.
Common Cataract Symptoms
- Blurred vision
- Difficulty reading
- Glare around lights
- Poor night vision
- Frequent spectacle number changes
- Faded color perception
Modern cataract surgery removes the cloudy lens and replaces it with a clear intraocular lens (IOL).
At ASG Eye Hospital, advanced cataract surgery technologies include:
- Phacoemulsification (Phaco Surgery)
- Micro-Incision Cataract Surgery (MICS)
- Laser-assisted cataract surgery
These advanced techniques help support:
- Faster visual recovery
- Smaller incisions
- Greater surgical precision
- Improved patient comfort
How Trifocal IOLs Work
Trifocal lenses use advanced diffractive optical technology to distribute light into three focal zones.
The Three Focus Zones Include:
Near Vision
Helpful for:
- Reading
- Mobile phone use
- Fine close-up work
Intermediate Vision
Designed for:
- Computer work
- Laptop screens
- Car dashboards
- Kitchen activities
Distance Vision
Supports:
- Driving
- Watching television
- Outdoor activities
The dedicated intermediate zone is one of the biggest advantages of trifocal lenses over older multifocal lens designs.

Many patients can comfortably perform:
- Reading
- Screen work

| Glass Dependence | Reduced | Usually needed |
| Lens Technology | Premium | Standard |
| Night Halos | Possible initially | Less common |
Trifocal vs Multifocal IOLs
Trifocal IOLs
- Near, intermediate & distance vision
- Better computer vision
- Improved digital lifestyle support
- Advanced optical design
Multifocal IOLs
- Usually near & distance focus
- Intermediate vision may be less sharp
- Older bifocal-style designs
Many eye specialists consider trifocal IOLs an advancement over traditional multifocal technology because of improved intermediate vision performance.
Who Is Suitable for Trifocal IOLs?
Trifocal lenses may be suitable for:
- Cataract patients seeking spectacle independence
