Is there such a thing as a subcapsular cataract?

Unlike what is typically thought of as a cataract, a Subcapsular Cataract – also referred to as a “secondary cataract” or an “after cataract” – occurs behind the eye’s lens. Causes of Subcapsular Cataracts. In certain situations, a Subcapsular Cataract can develop after surgery for a lens cataract.

What causes a posterior subcapsular cataract ( PSC )?

Posterior subcapsular cataracts (PSCs) result from the failure of epithelial cells to properly differentiate into elongated lens fiber cells. These aberrant cells migrate on the posterior lens capsule to the posterior pole of the lens, where they undergo aberrant differentiation and scatter light.

Is there a safe dose of GC for subcapsular cataract?

Posterior subcapsular cataracts are a well-described complication of prolonged GC use. Some clinicians believe there is no minimal safe dose with respect to this complication, and reports exist of cataract formation even with inhaled glucocorticoid preparations.

Is there any way to put off cataract surgery?

You can choose to put off having surgery for a while and have regular check-ups to monitor the situation. There are no medicines or eye drops that have been proven to improve cataracts or stop them getting worse. Before surgery, you’ll be referred to a specialist eye doctor for an assessment.

How long does it take to replace a cataract lens?

In almost all cases, cataract surgery is an outpatient procedure that takes around 20 minutes. During the procedure, an eye surgeon removes the clouded lens and replaces it with a plastic lens implant. The replacement lens sits in the same place your natural lens had been.

How is the posterior subcapsular cataract grading done?

The posterior subcapsular cataract grading is done according to vertical diameter. For multiple PSCs, only the most clearly visible opacities with distinct borders should be considered. The diagnosis of posterior subcapsular cataract is best done by slit-lamp examination.

When did ultrasound break up the cataract lens?

However, the risk has decreased since ultrasound has been used to break up the lens before removing it. Up until 1990, the lens was removed in one piece, including its capsule.
