Cataract Surgery

Cataracts and their treatments

A cataract is one of the most common reasons for diminished vision quality, and affects most people as they age. It is also the most frequent cause of blindness worldwide.

Patients often don’t realise they have cataracts until cloudy vision starts to dramatically impair their daily lives. Left untreated, a cataract may even lead to complete loss of vision. The good news is that a cataract can be treated easily and effectively with a safe, routine procedure. The replacement of the eye-lens blurred by a cataract with an Intraocular Lens (IOL) is currently performed over 20 million times per year worldwide1.
