June is cataract awareness month, a time to learn more about cataracts and their impacts. It is important to spread awareness about the condition and share valuable information about causes, symptoms, and treatments.
It is a great opportunity to encourage regular visits to your optometrist or ophthalmologist and remind everyone about the importance of timely care to keep vision sharp.
Cataract is the leading cause of blindness worldwide and can greatly affect quality of life. Cataract is responsible for approximately 45%of global blindness. Whilst sunlight exposure, genetics, health conditions and medications can influence cataract development, they are a normal part of aging. Cataract occurs when the naturally clear lens inside the eye becomes less clear over time, this can include fogging, dimming or blocking of vision and light. Symptoms can also include change in colour perception and glare sensitivity. Approximately half of all Australians aged between 65 and 74 have some form of cataract, increasing to more than 70% over the age of 75. Indigenous Australians are affected by blindness and bilateral vision loss due to cataract at a higher rate than non-Indigenous Australians, often with increased delays in diagnosis and surgery.
Cataract surgery involves removing the old, clouded lens and inserting a new, artificial clear lens. It is the most commonly performed elective surgery procedure in Australia and has evolved into one of the most successful operations in the western world. It is very effective at restoring sight.
Cataract surgery is not only important for restoring vision but also improving quality of life. Cataracts and their consequential vision impairment have been linked to reduced social engagement, increased mental health concerns and decreased physical activity.
