What Is Cataract Surgery?
A cataract develops when the eye’s natural lens becomes cloudy, leading to blurred and dim vision.
Common Cataract Symptoms
- Blurred vision
- Glare and halos around lights
- Difficulty reading
- Poor night vision
- Frequent spectacle power 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 options include:
- Phacoemulsification (Phaco Surgery)
- Micro-Incision Cataract Surgery (MICS)
- Laser-assisted cataract surgery
These techniques support:
- Faster recovery
- Smaller incisions
- Better surgical precision
- Improved patient comfort
How Multifocal IOLs Work
Multifocal intraocular lenses use advanced optical technology to create multiple focus points inside the eye.
This helps patients focus clearly at:
- Far distances
- Intermediate distances
- Near distances
Helpful For:
- Reading
- Computer use
- Smartphone screens
- Driving
- Everyday activities
The brain gradually adapts to the multiple focus zones over time after surgery.
