What Are the 3 Types of Cataracts??

A cataract is a clouding of the lens of the eye that impairs vision. There are three main types of cataract: Nuclear Sclerotic, Cortical and Posterior Subcapsular. The types of cataracts are classified based on where and how they develop in the eye.

What are the 4 types of cataracts?

Age-Related Cataracts. This type of cataract develops as a symptom of old age, especially in those who have smoked or had significant exposure to ultraviolet light. ….Congenital Cataracts. ….Secondary Cataracts. ….Traumatic Cataracts.

What are the 3 cataracts causes?

A cataract is a clouding of the lens of the eye that impairs vision. There are three main types of cataract: Nuclear Sclerotic, Cortical and Posterior Subcapsular. The types of cataracts are classified based on where and how they develop in the eye.

At what stage should cataracts be removed?

In most cases, you need surgery when blurry vision and other symptoms of a cataract starts to interfere with daily activities like reading or driving. There is no drug or eye drop to prevent or treat cataracts. Removing them is the only treatment.

What are the 3 main types of age-related cataract?

The 3 main types of age-related cataract are nuclear sclerotic, posterior subcapsular and cortical.

A cataract occurs when the lens of your eye becomes cloudy. Eventually, a cataract can advance to the degree of the one shown in this person’s right eye.

Fortunately, cataract surgery is generally a safe, effective procedure. Clouded, blurred or dim vision Increasing difficulty with vision at night Sensitivity to light and glare Need for brighter light for reading and other activities Seeing “halos” around lights Frequent changes in eyeglass or contact lens prescription Fading or yellowing of colors Double vision in a single eye

Most cataracts develop when aging or injury changes the tissue that makes up the eye’s lens. Proteins and fibers in the lens begin to break down, causing vision to become hazy or cloudy. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts.

A cataract scatters and blocks the light as it passes through the lens, preventing a sharply defined image from reaching your retina. A nuclear cataract may at first cause more nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and further clouds your vision.

Advanced yellowing or browning of the lens can lead to difficulty distinguishing between shades of color. A cortical cataract begins as whitish, wedge-shaped opacities or streaks on the outer edge of the lens cortex. A posterior subcapsular cataract starts as a small, opaque area that usually forms near the back of the lens, right in the path of light.

These cataracts may also be due to certain conditions, such as myotonic dystrophy, galactosemia, neurofibromatosis type 2 or rubella. Increasing age Diabetes Excessive exposure to sunlight Smoking Obesity High blood pressure Previous eye injury or inflammation Previous eye surgery Prolonged use of corticosteroid medications Drinking excessive amounts of alcohol Follow your treatment plan if you have diabetes or other medical conditions that can increase your risk of cataracts.

Adding a variety of colorful fruits and vegetables to your diet ensures that you’re getting many vitamins and nutrients. Studies haven’t proved that antioxidants in pill form can prevent cataracts. But a large population study recently showed that a healthy diet rich in vitamins and minerals was associated with a reduced risk of developing cataracts.

Cataracts are the clouding of your eye’s natural lens. A cataract begins when proteins in the eye clump together and block the lens from sending clear images to the retina. In turn, this effect causes the typical cataract symptoms such as blurry vision, glare, poor night vision, double vision, faded colors, or frequent changes in prescription lenses. Cataracts are common in older people, and over half of the people in the U.S. have cataracts or have gone through cataract surgery by the time they’re 80 years old.

Rather than suffer with bad vision, or be at risk for going blind, join the 2 million plus people each year who have cataract surgery.

The staggering reality is 24.4 million people age 40+ and older will develop cataracts. By the age of 75, that number rises to half the U.S Population. The development of cataracts is a natural part of aging, but eye injury as a side effect if other surgery can also cause the condition.

Cataract treatment is safe and quick, so dont put off seeing your eye doctor to discuss your options. The good news is that cataracts can be detected as part of a routine eye exam .

There are three primary types of cataracts: nuclear sclerotic, cortical, and posterior subcapsular they also have unique symptoms which are discussed below. The symptoms of this cataract are blurred vision, difficulty with glare, and changes in both contrast and depth perception. If you have diabetes or extreme nearsightedness you are at increased risk of this type of cataracts.

Individuals who use steroids, either recreationally or as part of medical treatment, are also at higher risk. With posterior subcapsular cataracts, you will first notice changes in your night vision. It is generally accepted that cataracts are a normal part of the aging process.

Ultraviolet radiation from the sun Diabetes Hypertension Obesity Smoking Significant alcohol consumption Prolonged use of corticosteroid medications Statin medicines used to reduce cholesterol Previous eye injury or inflammation Previous eye surgery Hormone replacement therapy The general theory is that a protein build up as a result of oxidative changes in the lens cause the development of cataracts.

As we age, the proteins aggregate and shift locations causing cloudy vision and cataracts. It appears that there is evidence to suggest that a diet high in antioxidants may help to prevent the development of cataracts. Exposure to ultraviolet light can increase your risk of developing cataracts.

Your first line of defense is to regularly wear sunglasses that block those harmful rays. Other ways to lower your risk of developing cataracts are associated with modifiable lifestyle behaviors. If you begin to experience the symptoms of cataract your first course of action is an appointment with your eye doctor .

In addition, they can support you by prescribing stronger glasses, bifocals, and other visual aids to improve your vision right now. After the surgery, patients return home and resume normal activities in a couple of days. You may also need progressive lenses to correct mild residual refractive errors as well as presbyopia.

Talk to your eye doctor about the benefits of anti-reflective coating and photochromic lenses which both protect your new sight. While there are 3 different types of cataracts the best way to determine a course of action is to visit your eye doctor. These include glaucoma, floaters and flashers, blepharitis, dry eyes, diabetic retinopathy, and macular degeneration.

3 Types of Cataracts

Cataracts are the clouding of your eye’s natural lens. A cataract begins when proteins in the eye clump together and block the lens from sending clear images to the retina. In turn, this effect causes the typical cataract symptoms such as blurry vision, glare, poor night vision, double vision, faded colors, or frequent changes in prescription lenses. Cataracts are common in older people, and over half of the people in the U.S. have cataracts or have gone through cataract surgery by the time they’re 80 years old.

Nuclear Sclerotic Cataracts

The most common type of age-related cataracts are caused by the gradual hardening and yellowing of the natural lens over time. It can take several years for nuclear sclerotic cataracts to affect vision. As the condition progresses, it affects the eye’s ability to focus. Sometimes, the developing nuclear cataract may temporarily improve close-up vision which is a symptom called ‘second sight’. That improvement is not permanent.

Cortical Cataracts

“Cortical” refers to the outer layer of something. With cataracts, it refers to a wedge shape which creates changes in the water content of the lens’ fibers. Cortical cataracts create clefts and fissures in patterns like the spokes of a wheel as well as cloudy areas. These cloudy areas cause light to scatter as it enters the eye, causing blurred vision and glare, as well as issues with depth and color perception. People with diabetes are at a special risk for developing cortical cataracts.

Posterior Subcapsular Cataracts

Symptoms of subcapsular cataracts include halos, glare around lights, and trouble seeing while reading. Often, the symptoms start as a small cloudy or opaque area on the back surface or ‘posterior’ side of the lens. These cataracts are called subcapsular because they form beneath the lens capsule, the small sac or membrane that encloses the lens and keeps it in place. This form of cataract is more common to people who use steroids, have diabetes, or struggle with extreme nearsightedness. These cataracts are the most rapidly developing cataracts and symptoms can become noticeable within months.

Nuclear Sclerotic Cataracts

Cataracts are a clouding of the lens in the eye. It is the result of the normal aging process and comes from a build-up of protein on the eyes lens.The onset of cataracts is slow and may not perceptible at first. The good news is that cataracts can be detected as part of a routine eye exam. The even better news is that surgery can correct your vision and get you back to seeing all of the things you love.Symptoms of cataracts will vary based on the type of cataract you develop.Overall, if you have or are developing a cataract you will notice a change in vision.Here are some other common symptoms:There are three primary types of cataracts: nuclear sclerotic, cortical, and posterior subcapsular they also have unique symptoms which are discussed below.

Cortical Cataracts

If you have diabetes, you are at higher risk of developing this type of cataracts.Cortical Cataracts start the reverse of the Nuclear Sclerotic Cataracts. It starts from the outer most layer of the eye. As it progresses it creates spokes that lead from the outside of the lens to the nucleus.The symptoms of this cataract are blurred vision, difficulty with glare, and changes in both contrast and depth perception.

Posterior Subcapsular Cataracts

If you have diabetes or extreme nearsightedness you are at increased risk of this type of cataracts. Individuals who use steroids, either recreationally or as part of medical treatment, are also at higher risk.With posterior subcapsular cataracts, you will first notice changes in your night vision. You may also notice more difficulty reading with this cataract.This cataract develops quickly, typically over months not years.If you think you have cataracts, see an eye doctor for an exam to find out for sure.

How Your Eyes Work

The general theory is that a protein build up as a result of oxidative changes in the lens cause the development of cataracts.

Cataract Prevention

There are several ways to reduce your risk of developing or delay the time until you develop cataracts.

Consume a Diet High in Antioxidants

It appears that there is evidence to suggest that a diet high in antioxidants may help to prevent the development of cataracts.Data from the 2nd National Health and Nutrition Examination Survey has shown that a diet high in Vitamin C lowers the risk of cataract development. This conclusion is supported by the Nurses’ Health Study.Consumption of Vitamin E also appears to be protective in the development of cataracts.This data is still evolving and there is some thought that certain vitamins may not prevent cataracts. The best course of action before starting any supplementation is to talk to your primary physician. Too much of some vitamins can be toxic.

Wear Sunglasses

Exposure to ultraviolet light can increase your risk of developing cataracts. Your first line of defense is to regularly wear sunglasses that block those harmful rays.

Lifestyle Modifications

Other ways to lower your risk of developing cataracts are associated with modifiable lifestyle behaviors.If you are overweight, losing weight may improve your diabetes or hypertension (if you have them). All of these, obesity, diabetes and hypertension, are risk factors for developing hypertension.If you smoke, you should stop. You should also only drink alcohol in moderation.These small changes can help to improve your overall health and the health of your eyes.

Cataract Treatment

If you begin to experience the symptoms of cataract your first course of action is an appointment with your eye doctor. They can determine if you are developing cataracts or not. In addition, they can support you by prescribing stronger glasses, bifocals, and other visual aids to improve your vision right now.An eye doctor can also track the progression of your cataracts if you have them. They can then help you to get the surgery you need to correct your visions once you eyesight progresses to that level.Although cataracts may be a natural part of aging, it can easily be corrected with surgery. You do not have to continue to suffer from less than ideal vision.

Cataract Surgery

Surgery for cataracts involves removing your cloudy lens and replacing it with a clear, plastic intraocular lens (IOL). There are other options for lens replacement that can be explored here.Cataract surgery is outpatient microsurgery. The surgery only takes a few moments and for most, no stitches are required. After the surgery, patients return home and resume normal activities in a couple of days.The result of the surgery is a lens clear of cloudiness and an improvement in your vision.

Eyewear after cataract surgery

After cataract surgery, you will need reading classes. That is unless you choose a presbyopia-correcting IOLs. You may also need progressive lenses to correct mild residual refractive errors as well as presbyopia.Caring for your eyes after cataract surgery is just as important as caring for them before surgery is needed. Talk to your eye doctor about the benefits of anti-reflective coating and photochromic lenses which both protect your new sight.Cataract treatment is simple regardless of the cause or type of your cataracts. The first step is to contact your eye doctor to assess your unique situation. Your eye doctor can improve your vision with either different prescriptions or cataract surgery.
