Cataracts: Do I Have Them? And More of Your Questions Answered

Baptist Eye Surgeons • February 8, 2021

Cataracts are the leading cause of blindness worldwide and your risk increases with age. If you’re at risk of cataracts, what begins as a little spot of cloudiness in your vision will only grow over time. Cataracts interfere with your ability to perform daily tasks and can prevent you from living the active lifestyle you’ve come to love.

At Baptist Eye Surgeons, it’s our mission to provide you with the highest quality of vision care possible. To help you understand more about cataracts, we’ll take a deep dive into every important aspect of the disease so you know what to look out for and what to do about it.

In this blog we’ll cover:

  • What is a cataract
  • Cataract symptoms
  • Types of cataracts
  • What causes cataracts
  • How to prevent cataracts
  • Cataract treatment
  • What to expect during cataract eye surgery

Cataracts are a serious condition, but they’re also a natural part of the aging process. While it’s important to be concerned about anything that can negatively impact your vision, you can rest easy knowing that our team of highly skilled surgeons have your back.

What Is a Cataract?

When healthy, the lens of your eye allows plenty of light to pass through and focuses it on your retina, allowing your eye to work similarly to a film camera. Unfortunately, the lens of your eye can become “clouded” over time, resulting in muddled or blurred vision. This is known as a cataract , and it can severely obstruct your vision and quality of life.

Cataracts are caused by the deterioration of proteins in the lens of the eye. These proteins begin to clump together as they break down, causing the lens to become:

  • Cloudy
  • Thicker
  • Less flexible

Cataracts can have severe repercussions for your vision if left undiagnosed or untreated. On the positive side, it can take years for the broken down proteins to become noticeable enough to affect your vision. Your best bet is to get regular comprehensive eye exams and stay proactive about your vision health. This will help our ophthalmologists catch cataracts early on and develop a treatment plan just for you.

Cataract Symptoms

Symptoms of cataracts can be easily shrugged off early on as minor annoyances. But they aren’t going anywhere once they’ve started growing. Their effects will only become worse as they grow and affect a larger portion of your lens. Pay attention to the symptoms of cataracts so that you know when it’s time to visit us at Baptist Eye Surgeons.

Cataract symptoms include:

  • Cloudy or blurred vision
  • Double-vision
  • Vision that’s faded or has a yellow tint
  • Increased sensitivity to light, such as glare
  • Seeing halos around lights
  • Multiple changes in your eyewear prescription

Experiencing one or even a couple of these symptoms may not seem like a cause for alarm since they’re similar to symptoms of other vision problems you may have. However, they may point to a much more serious eye condition. Even more concerning is that your symptoms won’t get better with time. Instead, they will worsen as the proteins in the lens deteriorate, causing your cataract to grow.

Types of Cataracts

There are different types of cataracts, and they are named based on where they develop on the lens of your eye. Their location can actually determine your symptoms. 

The different types of cataracts are:

  • Nuclear cataracts
  • Posterior subcapsular cataracts
  • Cortical cataracts
  • Congenital cataracts

Nuclear cataracts are the most common type of cataracts eye doctors run into. These cataracts affect the center of the lens of your eye, resulting in nearsightedness early on and even improved reading vision. Despite making it easier to see things up close, the lens will eventually become clouded, causing your vision to go from yellow to brown, making it more difficult to distinguish colors. 

Posterior subcapsular cataracts affect the back of the lense. They begin as a small, clouded area that prevents light from making it to the retina near the back of your eye. This type of cataract makes your reading vision worse, makes it difficult to see in bright light, and can cause glare or halos around light at night. Posterior subcapsular cataracts are more aggressive and tend to develop faster than the other types.

Cortical cataracts are located around the edge of the lens. They start as triangular clouded spots or even streaks near the edge of the lens. These abnormalities gradually stretch to the center of your vision, making it difficult for light to reach the retina, resulting in glare and affect your depth perception. Those with diabetes are at a higher risk for cortical cataracts.

Congenital cataracts are present at birth, though they can also develop during childhood. These types of cataracts may be related to genetics, trauma, or intrauterine infection.

What Causes Cataracts

Cataracts are caused by the breaking down of proteins in the lens of the eye, resulting in the lens becoming hard, less flexible, and cloudy. But this process can be caused by different factors. Knowing the different causes of cataracts, as well as factors that can increase your risk, can help you and your ophthalmologist know what to look out for during regular eye exams.

Cataracts and Getting Older

Aging is the most common reason for cataracts. Deteriorating proteins in the lens of the eye is a natural process that happens to everyone. It starts around the age of 40, with an estimated 24 million Americans having one by that time. By 75, over half of Americans are likely to have cataracts.

Early detection is key when it comes to cataracts. While they start to form around 40 years old, their symptoms don’t usually become noticeable until around the age of 60. Staying proactive about your overall and vision health is key. Keeping up with regular comprehensive eye exams can help catch them in their early stages and give you and your eye doctor time to talk about treatment options.

Family Health History and Cataracts

Your family health history plays an important role in your health and can even be used as a forecast for what to expect when it comes to cataracts. Most people will deal with cataracts eventually, but your genetics may point to a higher risk than others. Having even one close relative with cataracts can signal a much greater chance of developing them than someone who doesn’t.

Talk to your relatives about cataracts and any other medical conditions that may be common in your family. This can be an indicator of what you can expect in the future, your risk for developing cataracts, and what kind of symptoms to keep an eye out for. Make sure to let all of your healthcare providers know what you learn about your family history related to cataracts and other vision problems. 

Injuries to the Eye

Cataracts resulting from an eye injury are known as traumatic cataracts . They’re similar to glaucoma in that they can be classified as either “penetrating” or “blunt” injuries. Traumatic cataracts can develop differently and affect your eye in various ways. Your ophthalmologist will be able to determine the best treatment plan for your particular injury or trauma.  

Make it a priority to visit your eye doctor if you experience any kind of eye injury or eye trauma. Not only will they be able to treat the initial wound, but they’ll also be able to check for resulting cataracts, as well.

How to Prevent Cataracts

There isn’t a silver bullet for preventing cataracts. They’re a natural part of getting older, making them something that everyone will face at some point in their lives. While that may be true, certain strategies may be helpful in slowing down their effects or preventing them from developing earlier than normal.

Get Regular Comprehensive Eye Exams

They say a good offense is a good defense. In the case of cataracts, the best way to defend yourself from their effects is to regularly get comprehensive eye exams. Comprehensive eye exams are more in-depth than the kinds you may have received in the past. Those were acuity tests designed to catch vision problems that can be corrected with prescription eyewear.

Comprehensive eye exams, on the other hand, are able to detect problems that are much deeper. They enable your ophthalmologist to examine the back of your eye as well as the surface, providing a much fuller picture of your vision health. For cataracts, your ophthalmologist can examine the front of your eye using a biomicroscope and the back with an ophthalmoscope.

You’ll want to get a comprehensive exam once per year, especially if you have diabetes or are over the age of 40. This won’t only help your eye doctor catch cataracts. It will help them to identify any other problems with your eye health and develop a plan to treat them.

Stop Smoking

Some causes of cataracts are beyond our control. You can’t stop the aging process or change your DNA, but you can do something about risk factors like smoking. The CDC has reported that smokers have a significantly higher chance of developing cataracts than nonsmokers, so it’s best to quit now to slow down or even prevent them from developing early. 

If you are a smoker, your best option is to quit immediately. This will not only help in the fight against cataracts, but it can also help prevent smoking-related eye diseases such as age-related macular degeneration (AMD). By quitting now, you’ll help slow down or even prevent multiple health issues.

Manage Your Blood Sugar

Diabetes can have a huge impact on your health, including increasing your chances of developing cataracts. Experts aren’t sure why, but research has shown that people living with diabetes have a 60% higher chance of developing cataracts than those who don’t. 

Managing your blood sugar is essential for preventing cataracts as other complications related to diabetes. Those with type 2 diabetes who are able to lower their glucose levels by just 1% have seen their risk of cataracts drop by 19%. This will help prevent other diabetic eye conditions, such as diabetic retinopathy, as well.

Avoid Getting Too Much Sun

The light from the sun has tons of benefits, including helping you get better sleep, but it also has a dark side. Along with damaging your skin, prolonged exposure to UV radiation can increase your chances of developing cataracts or even speed up the process. This also goes for artificial sources of UV radiation like tanning beds.

You need to protect your eyes as much as you protect your skin when spending time outside. This means investing in a quality pair of sunglasses to protect your eyes for the long haul. When shopping for sunglasses, choose a pair that has:

  • High UV absorption (99 – 100% or 400nm)
  • A good fit to prevent as much light from entering as possible
  • Durable lenses

The quality of the lenses is also important. While you want to block UV rays, you don’t want to choose a pair that makes it difficult to see. You can test them by looking at the lines around objects when trying them on. Avoid sunglasses that create wavy lines and opt for a pair where lines are straight.

Cataract Treatment

The only effective treatment for cataracts is surgery. However, cataracts can usually be treated in their early stages with:

  • An updated prescription for contacts or glasses
  • Anti-glare glasses or sunglasses
  • Brighter lighting
  • Magnifying glasses

Eye doctors are likely to suggest these solutions during the early stages due to how cataracts grow. Cataracts typically grow very slowly. While they aren’t reversible without surgery, eyecare professionals are likely to wait until the cataract begins to interfere with your daily life before recommending surgery.

But don’t let the slow nature of cataracts lull you into complacency. They may not harm the eye, but cataracts can eventually make it much more difficult to engage in activities such as reading or driving at night. 

Make sure to have a plan in place once you have been diagnosed with cataracts. If you choose to delay surgery, then your doctor will keep tabs on how your cataract develops until they feel that it’s time. If you opt to go ahead with surgery, then your eye doctor may suggest follow-up exams to see how the treatment is progressing.

Eventually, your cataract will reach the point where solutions such as a new prescription, magnifying glasses, or brighter lighting will no longer do the trick. Cataract surgery is the only method of treatment that’s effective against cataracts. Without it, you’ll no longer be able to perform regular tasks like driving at night or living the active lifestyle that you love. This is often the point when most people qualify for cataract eye surgery.

Cataract surgery can do wonders for your vision and quality of life. Over 95% of patients experience improved vision after surgery, meaning that they can perform daily tasks the way they used to as well as return to the activities they once enjoyed. 

Our team of surgeons are leaders in the field of cataract eye surgeons. They are experienced with the latest advancements in cataract treatment, including the application of advanced artificial lenses. Our team is always staying at the forefront of the most innovative techniques and technologies, giving you a fast and secure return to your normal life.

What to Expect During Cataract Eye Surgery

The purpose of cataract eye surgery is to replace your old lens with a new one. The old lens has become clouded and occluded, making it at best an annoyance and at worst a genuine danger to your wellbeing. By replacing the old, clouded lens with a new one, you’ll be able to live your life to the fullest again.

You will be provided with a local anesthetic before cataract surgery. Patients are usually awake during cataract procedures, but the local anesthetic will numb your eye so you don’t feel anything during the operation.  

During the procedure, one of our surgeons will gently remove the old lens and replace it with a new, artificial one. This is known as an intraocular lens , and it can come in a couple of different types. One is the toric lens , which can correct astigmatism as well as improve distance vision. Another is a multifocal lens , which improves near, distant, and intermediate vision. In some instances, artificial multifocal lenses may even remove the need for corrective eyewear.

Unfortunately, prosthetic lens replacements aren’t right for everyone. This is often the result of having other eye disorders along with cataracts. But this doesn’t mean that your cataracts are untreatable! Patients in this position can still have their cataracts removed. In this case, prescription eyeglasses or contact lenses can be used to correct vision problems.

Despite the complexity of cataract surgery, we are able to perform cataract eye surgery on an outpatient basis. This allows us to complete the procedure as safely as possible while enabling you to return to your daily routine as quickly as possible.

Types of Intraocular Lenses

Intraocular lenses for cataract surgery come in three types:

  • Standard
  • Toric
  • Multifocal

Standard cataract lenses are usually covered by insurance and are helpful in treating nearsightedness and farsightedness. Unfortunately, they aren’t helpful in treating astigmatism. They can improve near vision and distance vision, but not both. You’ll need reading glasses with standard cataract lenses or possibly bifocals.

Toric cataract lenses are not covered by insurance. However, they are able to treat astigmatism along with nearsightedness and farsightedness. Like standard cataract lenses, they can fix near vision or distance vision but not both. They can help reduce your dependency on glasses but reading glasses may still be necessary.

Multifocal cataract lenses aren’t covered by insurance, but they are able to treat all forms of refractive error. They can also decrease your dependence on glasses, including the need for reading glasses. Some patients may not even need glasses at all while others may still need them for reading small print or driving at night.

Recovering from Cataract Surgery

Discomfort is common a few days after cataract surgery. The recovery process usually lasts around eight weeks, but most patients are able to return to their jobs shortly after the procedure. Office-workers can usually return to work a few days after surgery while those in vocational fields often go back after one week.

Healthy, clear lenses allow light to pass through to support your vision. Unfortunately, the lens can become thick, clouded, and hard. These are known as cataracts and can come in different types and have different causes. Although certain strategies may slow their progression or even prevent them from developing early, surgery will eventually become necessary to remove the cataract and its effects. Our team of Knoxville eye surgeons can perform cataract surgery on an outpatient basis and get you back on your feet as quickly and safely as possible.

Dry, itchy or watery eyes can make simple day to day activities quite uncomfortable, particularly if the symptoms are affecting your ability to read, work or enjoy time outside. The two most common causes of eye discomfort are dry eye disease and eye allergies. They can present in a very similar way so it's important to be able to differentiate between the two in order to know when you need to see an eye care professional. An eye examination at Baptist Eye Surgeons will help to establish the cause of your symptoms and will allow us to recommend the most appropriate treatment. What is the difference between dry eye and eye allergies? Dry eye disease is essentially the condition where your eyes either aren't producing enough tears or the tears produced are evaporating too quickly to adequately lubricate the surface of the eye. The result is typically irritation, redness, a gritty feeling and sometimes quite the opposite of what you'd expect in the form of excessive tearing. Eye allergies (allergic conjunctivitis) are basically your immune system reacting to an allergen (pollen, dust mites, mold, pet dander etc). The result of that reaction is the release of histamine and other mediators which can lead to itching, redness and swelling. As both conditions may result in red, watery and uncomfortable eyes, it's important to be able to recognize the specific symptoms in order to get to the root of the problem and find relief. Dry Eye vs. Allergies: Common Symptoms to Watch For Although there is some overlap between the two conditions there are certain symptoms which may help you to tell them apart. 1. Itchy Eyes vs. Burning and Grittiness One of the most obvious differences is the kind of discomfort you're suffering. Eye allergies are very much associated with intense itching (to the point where you're constantly itching the eyes) and with swelling of the eyelids. Dry eye disease is more likely to cause a burning, stinging sensation (as if something is in your eye) or a gritty feeling. Your eyes will often feel tired and/or irritated, particularly after reading, working at a computer or being in an air conditioned environment. 2. Watery Eyes and Excessive Tearing Both dry eye and allergies can lead to watery eyes, just that the mechanism is different in each case. With dry eye disease, irritation can trigger a reflex which results in an overproduction of watery tears. These tears may well be in fact more of a problem than a solution as they won't provide the sustained lubrication that your eyes require. With allergies you often get watery eyes along with itching, redness and swelling of the eyelids. These can become quite apparent after exposure to pollen, dust and so on. 3. Seasonal Symptoms and Environmental Triggers The timing of your symptoms can be of some use in terms of giving you a clue. Eye allergies are a common problem and tend to be worse at certain times of year (particularly when pollen counts are high). They can also occur year-round if you're exposed to indoor allergens such as dust mites and pet dander. Dry eye symptoms can occur all year round and can be made worse in dry, windy or air conditioned environments. Lengthy screen time, ageing, certain medications and some medical conditions may all contribute to dry eye disease. 4. How Symptoms Affect Both Eyes Allergic conjunctivitis will typically affect both eyes and is very often associated with quite marked itching. Dry eye can also affect both eyes, though the symptoms may be quite different in the two eyes. Neither pattern alone is definitive for determining the cause of eye irritation. How Are Dry Eye and Eye Allergies Diagnosed? An eye exam enables your eye care professional to assess your symptoms, take your medical history and look for any signs of irritation or inflammation. Depending on your symptoms, the testing may look at tear production, tear quality, tear evaporation and the surface of the eye. Your eye care professional may also look at environmental triggers and other conditions which may be playing a part in your symptoms. Accurate diagnosis is important as dry eye and allergies can require different treatments and in some cases both can be present at the same time. How can you find relief from eye irritation? Treatment is dependent on the etiology of your symptoms. Artificial tears may be of some help in the relief of dry eye discomfort, allergy medication or antihistamine eye drops may be of benefit in the management of allergic symptoms. Your eye care professional will be in a position to advise you on the most appropriate options for you. Don't rub your eyes and consider minimizing exposure to any known irritants/allergens. If the symptoms continue, get worse or keep coming back then you should have an eye exam rather than just carrying on treating them without knowing the actual cause. Get prompt medical attention for severe eye pain, sudden change in vision, intense light sensitivity or severe redness. Protecting Your Eye Health Knowing the difference between dry eye and allergies can go a long way to helping you understand your symptoms and get to the root of the problem so that you can take appropriate steps to alleviate them. The issue is that the two conditions can present with such similar symptoms that a proper assessment by a professional is often the only way to work out which one you actually have. If you are experiencing persistent itching, burning, redness, or watery eyes, schedule an appointment with Baptist Eye Surgeons. An eye care professional can help identify the source of your symptoms and develop a treatment plan to support your comfort and long-term eye health.

A thorough eye exam is an important part of keeping your vision healthy and protecting your eyes. If you are arranging for your first eye examination as an adult, if you are taking a child in for an evaluation, or if you have noticed any changes in your vision, knowing what to expect can help make the experience more comfortable. The eye exams carried out at Baptist Eye Surgeons not only check your vision but also look at your general eye health and spot any possible problems that might call for further investigation. What is the Importance of Eye Examinations? An eye examination does not merely enable one to find out if glasses or contact lenses are required. It lets an eye care professional assess how well your eyes are working and spot the signs of common eye conditions.  Some eye conditions can progress slowly without symptoms. Regular eye checkups can help detect changes earlier and make sure you receive appropriate treatment when needed. Step by step: The Process Involved in Having an Eye Examination Even though the different appointments may vary according to your particular needs, a typical full eye examination will involve a number of significant steps. 1. An Examination of Your Medical & Eye History Your appointment may start with questions about your vision, medical history, medications, any previous eye conditions, and your family history of eye disease. Be sure to report any changes in your vision, eye discomfort, headaches, or other concerns you have noticed. Your eye care professional may also ask about the glasses or contact lenses you currently use and how well they work for you. 2. Checking Your Vision A well-known part of an eye examination is the visual acuity test. You might be asked to read some letters or symbols from a chart at a set distance. This lets doctors assess how clearly you can see and decide whether corrective lenses would help. Further testing could assess your ability to see up close and the way well your eyes work together. 3. The Measurement of Eye Health & Function Your eye care professional might carry out a number of tests in order to assess the health and functioning of your eyes. The tests involved may vary depending on your age, symptoms, and risk factors and could include measuring eye pressure, examining eye movement and coordination, and looking at the structures at the front and back of the eye. They can help spot possible signs of eye disorders. 4. Discussing Your Results Your ophthalmologist will review the results with you after the examination. If your vision has changed, they may suggest new prescription lenses. If they spot an eye condition or another issue, they could recommend further testing, further monitoring, or treatment. It is also a good chance to ask questions regarding your eye health and the recommended follow-up care. What Should You do to Get Ready for your First Eye Examination? Having an eye examination usually involves nothing complicated. It is a good idea to take with you your present glasses or contact lens details and to be ready to give a list of any medications as well as any applicable medical or family history. Additionally, it might be helpful to remember any vision changes or symptoms you have had. Dilation may occur during the examination if certain tests are performed. After dilation has been advised, your vision might be temporarily blurred or more sensitive to light. Supporting Healthy Vision The initial eye examination is a valuable chance to determine a baseline for your eye health and understand your specific vision needs. Regular eye exams help monitor changes over time and support early detection of possible eye conditions. Plan a visit with an eye care professional if you have discovered any changes in your vision or if you're due for a check-up.

Healthy vision is essential for a child's development, learning, and daily activities. From recognizing faces in infancy to reading, participating in sports, and navigating school, children depend on their eyesight to interpret and relate to their environment. Knowing typical vision milestones helps parents spot possible issues and seek appropriate care when needed. How Does Vision Develop in Children? Vision develops rapidly during the first years of life. Newborns perceive light, shapes, and nearby objects, although their vision remains immature. As children mature, their capacity to focus, track moving objects, recognize details, and coordinate both eyes improves progressively. Due to the gradual nature of visual development, regular eye examinations are essential. Certain childhood vision problems may not be readily apparent, especially when one eye is stronger than the other. Although each child develops at an individual pace, several general vision milestones may guide parental observation. 1. Infants: Birth to 12 Months Within the first year, infants typically develop the ability to focus on faces and objects, visually track moving items, and reach for objects they observe. Caregivers may also observe infants responding to known faces and visually exploring their environment. If an infant does not track objects, exhibits eyes that frequently cross or wander, or fails to respond visually to people or objects, these concerns should be discussed with a pediatrician or eye care professional. 2. Toddlers: Ages 1 to 3 As children become more active, their visual skills continue to develop. Toddlers rely on vision to walk, climb, manipulate small objects, and interact with toys. Over time, they typically improve in identifying familiar people and objects and in coordinating eye and hand movements. Frequent eye rubbing, squinting, sitting close to screens, or difficulty seeing objects could indicate the need for an eye exam. 3. Preschool and School-Age Children By preschool and early elementary school, children utilize vision for detailed activities including coloring, drawing, letter recognition, reading, and participating in games. Effective eye coordination and focusing abilities support learning and classroom performance. Children may not always realize their vision differs from other children’s, so parents should watch for signs such as headaches, avoiding reading, losing their place while reading, holding books unusually close, or struggling to see the board. Signs of Possible Vision Problems Caregivers should monitor for changes in a child's vision or behavior. Potential warning signs include: Frequent squinting or eye rubbing Eyes that cross, wander, or do not move together Complaints of blurry or double vision Frequent headaches Difficulty reading or concentrating Sitting very close to a television or screen Tilting or turning the head to see Covering or closing one eye Difficulty recognizing objects or seeing at a distance Avoiding activities that require close or distance vision If you notice these signs, speak with a pediatrician or eye care professional. The Importance of Children’s Eye Exams Regular eye examinations can identify vision problems before they interfere with learning and development. Eye care professionals assess visual acuity, binocular coordination, and common childhood eye conditions. Early detection matters because some vision problems are easier to address when identified in childhood. Parents must follow their child’s healthcare provider's recommendations for vision screenings and comprehensive eye exams. Helping Protect Your Child’s Vision Caregivers can promote healthy vision by encouraging beneficial habits. These include spending time outdoors, taking regular screen breaks, using appropriate protective eyewear during activities, maintaining a balanced diet, and attending recommended pediatric and eye care appointments. Supporting Healthy Vision at Every Age Knowing children's vision milestones helps caregivers distinguish typical development and spot possible issues early. Throughout infancy and the school years, monitoring how a child sees, focuses, and interacts with their environment is vital for supporting healthy development.  If you notice concerns about a child's eyesight or alterations in vision, consult a healthcare provider or eye care professional. Early attention to vision supports learning, development, confidence, and overall quality of life.
