Cataract is the opacification (clouding) of the crystalline lens in your eye.
This causes hazy or blurred vision, halose and smaller pieces which are emulsified around light sources, double vision and difficulty in reading in dim light.
They are usually age related.
They need to be operated on when the vision cannot be improved with glasses and causes difficulty in day to day activities.
Cataract surgery is performed by phacoemulsification (ultrasonic energy) which fragments the cataract into smaller pieces and emulsified.
This is a suture less procedure.
We also perform femto bladeless cataract surgery - Lensx.
