Complex cataract is also known as complicated cataract.

What is Complex Cataract?

In the same way that a usual cataract develops, a complicated cataract also occurs when the lens at the front of the eye starts to become cloudy.

This prevents the retina from receiving light rays in the way they should, causing vision to become impaired.

These will eventually need to be treated, as the condition will only continue to progress over time, and vision will continue to deteriorate. With the complicated cataract, the progression can be more rapid and dramatic, as the posterior central part of the lens is affected. Unlike a cataract that forms as a result of ageing (senile cataract), complex cataracts can be just as common in children as they are in adults.

What Are the Causes of Complex Cataract?

Complicated cataracts are usually caused by inflammatory eye conditions such as iritis or uveitis. Other causes include: injury / trauma, glaucoma, medications (Doxazosin, Tamulosin), high blood pressure, severe cough and chronic anxiety. Blindness can occur if the condition is left untreated.

What Is the Treatment for Complex Cataract?

When a complicated cataract has developed the only effective solution would be to have it removed. At Prema this will need to be done using ultrasound during cataract surgery, or through laser guided cataract surgery that uses femtosecond laser technology.

Our surgeons are highly trained and experienced, and will always perform the most suitable procedure for the individual patient.
