Cataracts are the commonest cause of vision loss in people over the age of forty. They are caused by ageing of the natural lens of the eye which then loses its transparency and becomes cloudy. For most people the treatment consists of a 15-20 minute surgical procedure to remove the cloudy lens and replace it with a clear artificial implant.

However, if you suffer from diabetes you face a 60% greater risk of the developing cataracts and you are more prone to developing infections, inflammation and worsening of retinopathy after cataract surgery. The success of your cataract operation will depend on careful assessment of the main cause of your blurred vision. A pre-operative OCT scan is always carried out to detect swelling of the retina (macular oedema). If diabetic macular oedema is diagnosed, it must be treated before the cataract surgery is attempted. Further treatment is given at the time of cataract surgery and continued several months after.

If you have macular degeneration, cataract surgery carries a guarded prognosis, which means that the extent to which the sight can be restored cannot be guaranteed. Despite this, with magnifying lens implants, the timely use of intraocular injections and realistic expectations, you can experience unprecedented visual results following cataract surgery. You must understand that underlying macular degeneration can limit your sight despite successful cataract surgery and that there are options to maximise the result.

The Scharioth intraocular lens implant is a pioneering magnifying lens implant that is designed to improve vision in eyes with poor vision due to macular degeneration or diabetes.
