Cataract Surgery in Saipan May Improve Brain Health

Posted by

A recent study from England has found that people who have had cataract surgery have better mental function in later life. The report joins a growing body of research that suggests that taking care of vision has benefits for older adults beyond just improving sight.

Researchers compared the rates of cognitive (thinking) decline before and after patients had cataract surgery. The researchers found the rate of cognitive decline was slowed by 50 percent following cataract surgery over 13 years of follow-up. The rate of decline among people who had cataract surgery was slower after the surgery compared with beforehand and became similar to the decline among those with no cataracts. 

“Cataract surgery is very commonly performed in the CNMI, and there are thousands of patients who have received this excellent surgery at Marianas Eye Institute,” said Russ Quinn, CEO of the Saipan eye clinic.

The researchers note that scientists still don’t know why vision problems affect cognitive decline. But they think that the isolation, embarrassment and lack of physical activity from vision problems may contribute to the problem.

“There is little doubt that cataract surgery is very likely to improve a person’s vision, which can allow people to stay active and independent,” said Thomas Steinemann, MD, professor of ophthalmology at Case Western University and an ophthalmologist at MetroHealth Medical Center in Cleveland. Dr. Steinemann wasn’t involved in the English study. “If you can’t do things for yourself because you can’t see well, it’s easy to fall into a depression and withdraw from activities. This could affect a person’s cognitive abilities.”

Marianas Eye Institute uses advanced surgical techniques for the removal of cataracts. If your vision is blurry, it may be from cataracts, which can be treated. Make an appointment today, or just walk in.

Too Much Screen Time?

Posted by

A recent study found that the average office worker spends 1,700 hours per year in front of a computer screen. And that doesn’t include our addiction to phones and other digital devices. All this screen time has led to an increase in complaints of eye strain, dry eye, headaches and insomnia. During Workplace Eye Wellness Month in March, Marianas Eye Institute joins the American Academy of Ophthalmology in offering tips to desk workers everywhere whose eyes may need relief from too much screen time.

Why does computer use strain the eyes more than reading print material? Mainly because people tend to blink less while using computers. Focusing the eyes on computer screens or other digital displays has been shown to reduce a person’s blink rate by a third to a half, which tends to dry out the eyes. We also tend to view digital devices at less than ideal distances or angles.

Simple Tips

You don’t need to buy expensive computer glasses to get relief. In fact, a study published last month concluded that blue light filters are no more effective at reducing the symptoms of digital eye strain than a neutral filter. Instead, try altering your environment with these simple tips:

  • Keep your distance: The eyes actually have to work harder to see close up than far away. Try keeping the monitor or screen at arm’s length, about 25 inches away. Position the screen so your eye gaze is slightly downward.
  • Reduce glare: Glass screens can produce glare that can aggravate the eye. Try using a matte screen filter.
  • Adjust lighting: If a screen is much brighter than the surrounding light, your eyes have to work harder to see. Adjust your room lighting and try increasing the contrast on your screen to reduce eye strain.
  • Give your eyes a break: Remember to blink and follow the 20-20-20 rule. Take a break every 20 minutes by looking at an object 20 feet away for 20 seconds. Looking into the distance allows your eyes to relax.
  • Keep eyes moist: Keep artificial tears at hand to help lubricate your eyes when they feel dry. Consider using a desktop humidifier. Office buildings have humidity-controlled environments that suck moisture out of the air. In winter, heaters on high can further dry your eyes.
  • Stop using devices before bed: There is evidence that blue light may affect the body’s circadian rhythm, our natural wake and sleep cycle. During the day, blue light wakes us up and stimulates us. So, too much blue light exposure late at night from your phone or other devices may make it harder to get to sleep. Limit screen time one to two hours before bedtime. Use nighttime settings on devices and computers that minimize blue light exposure.

When to visit Marianas Eye Institute

“Eyestrain can be frustrating. But it usually isn’t serious and goes away once you rest your eyes or take other steps to reduce your eye discomfort,” said Dianna L. Seldomridge, M.D., clinical spokesperson for the American Academy of Ophthalmology. “If these tips don’t work for you, you may have an underlying eye problem, such as eye muscle imbalance or uncorrected vision, which can cause or worsen computer eyestrain.”

Those experiencing consistently dry red eyes or eye pain should visit one of the specialists at Marianas Eye Institute.
