Trauma-related cataracts are typically the most fast-growing type of cataracts. Radiation: Radiation-related cataracts, sometimes listed under trauma-related cataracts, occur after the lens has been exposed to radiation. Exposure to high levels of radiation can result in clouded vision in as little as two years.
Because most age-related cataracts typically develop over a span of years, it's a relatively slow process. However, some types of cataracts may develop faster, such as in individuals with diabetes, where cataracts can develop rapidly.
At first, you may not notice that you have a cataract. But over time, cataracts can make your vision blurry, hazy, or less colorful. You may have trouble reading or doing other everyday activities. Over time, cataracts can lead to vision loss.
Because emotional or psychological stress is associated with increased oxidant production and oxidative damage, long-term exposure to emotional or psychological stressors may enhance the risk of many diseases associated with oxidative stress, including cataracts.
On the other hand, posterior subcapsular cataracts are known to develop quickly in the eye. In some cases, patients can go from clear vision to blind in a matter of months. While the type of cataract plays a significant role in formation, other factors can also play a part.
If cataracts are left untreated, they will eventually cause significant disruption in everyday life and interfere with normal activities like driving a car or watching television. Ultimately, complete vision loss will result.
Cataracts reduce the amount of light traveling to the retina, which could significantly misalign the way your body regulates sleep (circadian rhythm). This can create uneven sleep patterns, drowsiness, and cognitive issues.
Stage 4: The Moderate Cataract
The lens may be yellow (nuclear cataract). There may be white spokes radiating from the sides (cortical cataract). Spots can collect on the posterior surface of the lens (posterior subcapsular cataract). All cataracts cause blur, glare, and loss of contrast.
Cloudy or blurry vision
This is the most common symptom of cataracts. It can affect both distance and reading vision which may appear foggy. If left untreated, the clouding of the lens means the cataract will worsen, with less light able to get through the lens.
Although, the vision loss is only temporary in many cases as long as you rehydrate your body with plenty of water. If you experience constant eye dehydration, this can increase the risks of developing cataracts sooner.
The inhibitory effect of caffeine against cataract formation is thus statistically highly significant. The cataract-lowering effect becomes highly visible as the caffeine consumption levels reach near 50 mg and then nearly complete at 100 mg/day.
If you aren't sure if your cataract is bad enough to have surgery or if Medicare will pay for it, consult with your eye doctor or cataract surgeon. Untreated cataracts can become "hyper-mature" — a condition that makes them more difficult to remove and more likely to cause cataract surgery complications.
Although it's never too late to have a cataract removed, it is better to have cataracts removed while they are immature, as this reduces the length of surgery and the recovery time. Earlier removal also means that you avoid the significant visual impairment associated with very mature (hypermature) cataracts.
Mature cataract.
Your eyes may even look milky in appearance. This is the optimal point at which cataract surgery can be performed.
Subcapsular cataracts can interfere with reading and create halo effects and glare around lights. People who use steroids or have diabetes, extreme nearsightedness, and/or retinitis pigmentosa may develop this type of cataract. Subcapsular cataracts can develop rapidly and symptoms can become noticeable within months.
A recent study found that people with cataracts often experience poor sleep quality. Advanced cataracts can reduce the amount of light that reaches the retina in the back of the eye, and this may cause an abnormal circadian rhythm that affects sleep.
Cataracts are caused by changes to the lens of your eye, mostly associated with ageing and exposure to ultraviolet light. Cataracts develop when proteins in the lens are damaged and clump together. This reduces the amount of light that can pass through the lens to the retina, which leads to a loss of vision.
Oxidative stress in eye lens is one of the main causes of the cataract. Dietary antioxidants including vitamin A and C are therefore known to be associated with the risk of the disease.
For the vast majority, cataract surgery is not urgent, and can be safely delayed until the person wishes to pursue surgery. Delaying surgery does not cause harm to the eye, however the vision just gets worse over time until the cataract is removed.
Over time, cataracts become worse and start to interfere with vision. Important skills can be affected, such as driving, and loss of vision can affect the overall quality of life in many ways including reading, working, hobbies and sports. If left untreated, cataracts will eventually cause total blindness.
Cataract surgery is irreversible. This is because the cloudy natural lens that results in a cataract is removed during surgery and cannot be placed back in.
Because vision is temporarily affected by cataract surgery, only one eye can be corrected at a time. In most cases, you'll need to wait for 2 to 6 weeks for your eye to heal completely before proceeding with the second eye. This allows the eye doctor to ensure everything is healing properly without complications.
