If you notice any change in your vision please book an eye exam appointment. During each and every eye examination our optometrist's will analyse your crystalline lens to determine if Cataracts is forming.
If we do detect Cataracts your treatment will depend on the severity of the Cataracts. Changing the lenses in your eyewear will temporarily improve your vision but once the lens opacity is too dense we will need to refer you to an eye specialist (Ophthalmologist) who can perform Cataract surgery. Cataract surgery involves removing the natural crystalline lens of the eye and will be replaced with an artificial crystalline lens implant.
Increased risk of Cataracts forming are:
- Eye injury or inflammation
- Excessive amounts of drinking alcohol
- Excessive exposure to sunlight
- Exposure to ionizing radiation (X-rays and cancer radiation therapy)
- Family history
- High blood pressure
- Previous eye surgery
- Prolonged use of corticosteroid medications
As we age the tissues within the crystalline lens to become thicker and it loses its flexibility and transparency. This starts to create cloudy areas within the lens which then scatters the light as it passes through the lens and prevents a sharp and defined image from reaching your retina. As a result, this blurs your vision.
Cataracts develops from aging or injury that changes your eye's tissue. There can be some genetically inherited disorders that can increase the risk of Cataracts forming, such as; diabetes, any eye trauma, or any previous eye surgery. There is no pain associated with cataracts but common symptoms include; blurred vision, appearance of spots, and increased sensitivity to glare.
Congenital Cataracts - This is where you are born with Cataracts and sometimes doesn't affect your vision but if it does they are usually removed soon after detection. Detection can be made at the child's first eye exam. It 's commonly a result of the mother having contracted an infection during pregnancy, or other conditions such as; myotonic dystrophy, galactosemia, lowe's syndrome, and rubella.
Cortical Cataracts - This is where the Cataracts affects the edges of the crystalline lens. At first you have whitish streaks on the outer edge of your vision. As it progresses the streaks begin to widen into the center of your lens and you experience problems and sensitivity to glare.
Nuclear Cataracts - This is where the Cataracts affects the center of the crystalline lens. At first you may become nearsighted and possibly even experience improvement in your reading vision but eventually your lens will turn yellow and further blur your vision. As this progresses the lens will turn brown and distinguishing between shades of color becomes even harder to do.
Posterior Subcapsular Cataracts - This is where the Cataracts affects the back of the crystalline lens. At first you have a small opaque area that forms right in the path of light on its way to the retina, which affects your reading vision, causes glare around lights at night, and even reduces your vision in bright lights.
N- Acetyl-carnosine Eye Drops (NAC) - There are scientific reports that support the findings that NAC improved vision in cataract patients. The authors called this ‘a snow melting effect’ referring to the slow reduction of the cataractous tissues in the lens following the use of NAC eye drops... learn more about our Vision Clarity Eye Drops
