Symptoms may include faded colours, blurry or double vision, halos around light, trouble with bright lights, and difficulty seeing at night.

Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye.

This procedure minimises the incision size and reduces the recovery time and risk of surgery-induced astigmatism.
