Posterior Subcapsular Cataract

What is a Posterior Subcapsular Cataract?

A Posterior Subcapsular is a type of cataract that begins as a small spot near the back of the lens, impacting reading, reducing vision in bright light and causing glare and halos around lights at night.


Common symptoms of Posterior Subcapsular Cataract

Posterior subcapsular cataracts develop rapidly compared to other types, so it’s crucial to watch out for symptoms like:

Blurry vision

Glare and halos, especially when exposed to bright lights, like headlights at night

Defective near vision

Double vision

Here’s how our experts treat it

At Vasan, we perform surgery to treat Posterior Subcapsular Cataract:


Phacoemulsification surgery involves using an ultrasonic probe to break up the cataract and remove the lens material through a small incision (2-3mm). A foldable intraocular lens (IOL) is implanted in the eye, restoring clear vision.


Posterior Subcapsular Cataracts are diagnosed through slit-lamp and ophthalmoscopic examinations.

Maintain strict blood sugar control. Protect the eyes from blunt trauma and avoid long-term steroid use.

Posterior Subcapsular Cataracts are commonly linked to ageing but can also result from factors like trauma, corticosteroid use, radiation exposure, heavy alcohol consumption, and inflammation.

It typically impacts reading vision and can reduce clarity in bright light, causing glare or halos around lights at night. These cataracts tend to progress faster than others.

Rosette Cataract

Rosette Cataract is a form of traumatic cataract caused by either blunt force trauma or penetrating eye injury.

Traumatic Cataract

Traumatic Cataract is the clouding of the lens due to eye trauma, either blunt or penetrative, which damages the lens fibres.


Cataracts occur when the eye's natural lens becomes cloudy, causing vision to blur like looking through a foggy or dusty car windshield.
