Cataract is defined as any opacity, or clouding, of the natural crystalline lens which is positioned within the eye.
What is a cataract?
People are normally born with a clear lens within the eye which is important in focusing light and blocking harmful ultraviolet rays.
Clouding of the lens, or cataract, develops with normal ageing of the eye and may be worsened by other conditions including excessive ultraviolet light exposure, diabetes, smoking, and injury.
Cataract surgery involves removing the clouded lens and replacing it with a clear lens implant which remains within the eye.
Cataract surgery
Cataract surgery is generally performed as a day procedure under local anaesthetic with sedative medications.
Under the operating microscope small incisions are made to enter the eye and access the cataract. This is broken up with a specialised instrument using ultrasound energy. A new lens is then implanted within the eye. A post-operative dressing is applied and post-operative antibiotic and anti-inflammatory drops are commenced, usually for several weeks.
There are a range of artificial intraocular lens implant options available including ‘advanced technology intraocular lenses’ which aim to reduce glasses dependence. Dr Northey will assess your suitability for different lens options and discuss these with you at the time of consultation.
