A cataract cannot be corrected using glasses. The only permanent treatment for cataracts is surgical removal which is usually a quick, safe and painless procedure taking about 20 minutes per eye and is performed under local anaesthetic. Usually one eye is treated at a time.


Removal is by microsurgery and essentially the cloudy lens in your eye is broken up and a new clear lens called an intraocular lens (IOL) is implanted. The intraocular lens is designed to last a lifetime.


At iSIGHT, we have a range of lenses to suit your lifestyle and your prescription. Your surgeon will discuss the range of lens options available to you. These lenses include multifocal, allowing you to focus at varying distances, and toric lenses to correct astigmatism.
