Can Cataract Surgery Prevent Dementia?

Cataract surgery is a highly successful procedure that removes cataracts, the cloudy formations on the eye’s lens that impair vision.

Now, researchers are discovering that vision loss may be linked to a higher rate of dementia and suggest that restoring clear vision (through cataract surgery, for example) may reduce the risk of developing dementia.

Is There a Correlation Between Cataracts and Dementia?

More than half of those 80 or older have had at least one cataract. Many people in this age range also have dementia, a decline in cognitive functioning.

But is there a connection between these two seemingly unrelated conditions?

Recent studies suggest that, yes, there could be a link. One 15-year study found that patients with age-related vision problems, including cataracts, had a higher incidence of dementia.

The 2021 study, published in the British Journal of Ophthalmology, followed 12,000 subjects aged 55-73. When compared to patients with healthy vision, cataract patients had an 11% higher incidence of dementia.

Can Cataract Surgery Prevent Dementia?

Can sight-saving cataract surgery reduce your risk of dementia? It certainly looks promising!

A 2022 study published in JAMA Internal Medicine found that removing cataracts was “significantly associated with a lower risk of dementia development.” In fact, patients who had undergone cataract surgery had a 29% lower rate of dementia.

In addition, MRI scans have shown greater brain activity following cataract surgery.

How Can Vision Loss Cause Dementia?

Scientists studying the link between vision loss and dementia suspect that vision loss negatively impacts the brain. They theorize that the more visual information we receive, the more active our brains are, and brain activity may be able to fend off dementia.

For this reason, by restoring clear vision, cataract surgery may stimulate the brain and prevent cognitive decline.

There could be an emotional and social dimension to cognitive decline as well. People who suffer from significant vision loss often feel isolated. They may feel discouraged by their inability to recognize faces or perform everyday tasks, and may avoid social interactions. According to the Centers for Disease Control, social isolation raises the risk of developing dementia by 50%.

If you have cataracts and you feel your quality of life is affected, schedule an appointment with Professional Family Eyecare in Royal Palm Beach without delay. We’ll answer your questions about cataract surgery and ensure you receive optimal treatment.

Q&A With Our Optometrist

How is cataract surgery performed?

Cataract surgery is a short 30-40 minute procedure that replaces your cloudy, natural lens with a synthetic intraocular lens (IOL). First, the eye surgeon makes a hole in the cloudy lens and breaks it into tiny pieces. Next, the eye surgeon places the new clear lens onto the eye. You’ll be conscious throughout the surgery. The surgery is safe, effective and painless.

Is cataract surgery always successful?

Cataract surgery is highly successful, with a 99% success rate. Complications from cataract surgery are very rare.

June 27 Is National Sunglasses Day!

Monday, Jun 27, 2022 is National Sunglasses Day, so grab your favorite pair of sunnies and celebrate!

Many people think sunglasses are little more than a fashion accessory or a way to minimize glare while driving.

But the truth is that wearing sunglasses is vital if you want to safeguard your eye health and vision.

Why Sunglasses are Important

The number one reason to wear sunglasses is that they prevent ultraviolet (UV) light from entering your eyes.

UV light has been shown to age every part of the eye, from the delicate outer eye tissue to the tiny structures within the eye itself. Chronic UV exposure raises your risk of developing cataracts, age-related macular degeneration and corneal damage.

The skin on your eyelids is the thinnest skin of your body, and UV light exposure can further thin eyelid skin, leading to premature aging and the appearance of dark circles and under-eye bags. Additionally, wearing sunglasses can help prevent wrinkles because you’ll squint less in the sunshine. Who knew sunglasses can be a key player in your anti-aging routine?

Moreover, UV light has been shown to slow the cornea’s ability to heal itself, making sunglasses a medical necessity for people who’ve recently had eye surgery like LASIK, or those who frequently wear contacts (overwearing contacts can irritate the cornea).

Finally, sunglasses are a fun way to show the world your personality and accessorize any outfit.

Activities for National Sunglasses Day

Not sure how to celebrate National Sunglasses Day? Here are a few ideas you may enjoy.

Sport your favorite pair of sunglasses during an outdoor activity, whether it’s a barbecue with friends, a concert at a stadium or time spent in the park.

You can also celebrate National Sunglasses Day by gifting a pair of quality sunglasses to a friend, spouse or child!

No matter how you choose to celebrate National Sunglasses Day, we hope you enjoy and keep your eyes protected.

FAQ With Our Optometrist

Should kids wear sunglasses?

Yes, children of all ages should wear sunglasses whenever they’re outdoors. In fact, it’s crucial because a child’s crystalline lens within the eye is much more clear than an adult’s, letting more light through. Contact us to learn more about kids’ eye health or to schedule an eye exam.

Can sunglasses block blue light?

Sunglasses with lenses that have a yellowish tint offer the most amount of blue light protection, from the sun and other sources. If you’re interested in blocking the blue light that’s emitted from your digital devices, speak with us to determine if computer glasses are right for you.

Could Working From Home Be Hurting Your Vision?

Working at home is a great way to ditch your commute and enjoy more flexible hours, but there can be an unexpected consequence—digital eye strain. If you’re like many workers, you probably spend most of your day on a computer or other digital device, and likely experience the headache, blurred vision, sore eyes or achy back so common with digital (computer) eye strain.

In contrast to being in the office, where workers take coffee breaks and socialize, working solo at home often translates into spending more time on the computer without breaks, and often beyond the typical 9 to 5 schedule. This can increase the likelihood of developing digital eye strain.

What Is Digital Eye Strain?

Digital eye strain, also called computer vision syndrome (CVS), affects an estimated 70% of adults, especially those between the ages of 18 and 34.The eye strain results from extended hours focusing on a computer screen, and may be worsened by hours of exposure to blue light, high-energy visible light emitted by digital screens.

Blue light can cause short-term eye strain and discomfort, and scientists are researching whether it could also be linked to serious eye conditions, such as age-related macular degeneration (AMD) and cataracts.

Moreover, staring at a screen, or even a printed book, causes people to blink up to 66% less often. Blinking is essential as it hydrates your eyes and stimulates the release of oil from the tiny glands in your eyelids. This oil also prevents tears from evaporating too quickly, thus drying out the eyes. Dry eyes can cause blurry vision, which further exacerbates eye strain.

What Are the Symptoms of Digital Eye Strain?

The following are common symptoms of digital eye strain:

  • Blurry vision
  • Eye soreness
  • Headaches Dry eyes
  • Light sensitivity
  • Neck, back and shoulder pain

How Can I Prevent Digital Eye Strain?

No need to ditch your job in order to avoid eye strain. There are other, more practical, ways to lessen the negative impact of screen time on our eyes. Below are some helpful tips.

Take Breaks

Even if you aren’t at the office and may not have co-workers to hang out with at the coffee machine or water cooler, make sure to take frequent breaks that don’t require screen time. Perhaps take a walk or reward yourself with a short nap. These breaks not only give your eyes a rest, but can rest your mind for a few minutes so you can work more efficiently.

Consider adopting the 20/20/20 habit. For every 20 minutes you spend in front of a screen, take a 20-second break and look at something 20 feet away. This will prevent you from overstraining your eyes and will encourage you to blink more, providing your eyes with much-needed hydration.

Adjust Screen Brightness

Bright screens can place a significant burden on your eyes. Simply adjusting your screen’s brightness can help rest your eyes.

See Your Eye Doctor

If you spend prolonged periods in front of the screen, it’s important to schedule an eye exam with your eye doctor to discuss whether you would benefit from lubricating eye drops or a pair of computer glasses. These computer glasses (or blue light glasses) allow your eyes to relax and make you feel as if you’re focusing on faraway objects. They also reduce glare and filter out blue light.

Whether you’re suffering from any of the symptoms related to digital eye strain or simply want to prevent it, we invite you to book an appointment with Professional Family Eyecare in Royal Palm Beach. With the right eye care and work habits, you should be able to successfully and quickly reduce and prevent eye strain.

Q&A With Our Optometrist

How long does it take to recover from computer eye strain?

If you don’t have an underlying eye condition, symptoms of digital eye strain can sometimes disappear within a few hours or days. But if you have recurrent eye strain, speak with your eye doctor, as the right eye drops or computer glasses could improve your visual comfort and quality of life.

Can digital eye strain affect my work productivity?

You may think spending hours in front of a computer screen will improve your productivity, when in reality, it may have the opposite effect. According to a study at the University of Alabama/Birmingham School of Optometry, even minor vision problems, such as eye strain, disrupt worker productivity by at least 20%.

So make sure to take steps to control lighting and glare on the device screen and establish proper working distances and posture for screen viewing. To learn more and to alleviate or prevent eye strain, contact Professional Family Eyecare today.
