Getting older is inevitable, and aging is often accompanied by changes in vision. As people get older, many struggle with cataracts. Words in books may become blurred, it may be difficult to focus on a computer screen, and oncoming car headlights may become more bothersome. This is because the clear lens in our eyes can become cloudy (referred to as a cataract) and blur our vision as we age. Seniors with cataracts are more likely to suffer from trips, falls, and even motor vehicle accidents. If not treated properly, cataracts can be blinding. In fact, cataracts are one of the leading causes of blindness worldwide1, impacting more than 35 million people across the globe2.

My mom, Susan (73), was one of them. She found that not only was it difficult to read her computer or her phone, but objects in the distance appeared fuzzy and indistinct. Like many, she first tried to fix it by wearing bifocal glasses; but as an ophthalmologist, I knew this wouldn’t fix the root of the problem. In fact, bifocal, trifocal, and progressive glasses can actually increase the risk of trips and falls by impairing both depth perception and edge-contrast sensitivity (the ability to distinguish subtle differences in shading) when looking down to walk. This can cause a person to misjudge their foot placement or fail to negotiate steps or raised surfaces well.3,4,5

Falling related to bifocal glasses is a significant danger to seniors—and something I worried about for my mother. In fact, falls are the leading cause of injury for older people6, and they lead to more deaths in seniors than diabetes7. Needless to say, quality of vision is also vital for safe driving, among many other necessary day-to-day activities.

 

Cataract Surgery Has Evolved

For these reasons, I encouraged my mom to consider cataract surgery. During this outpatient procedure, an ophthalmologist (eye surgeon) removes the cloudy lens and replaces it with a clear artificial intraocular lens (IOL), which helps patients see more clearly and with greater contrast. This procedure is quite routine and is one of the most commonly performed surgeries in the United States. 8

We’ve seen big advances in cataract surgery in recent years, particularly in the IOLs available. Today, we can use the procedure to correct not only the cataract, but also presbyopia (losing the ability to see at near ranges) and astigmatism (an oblong eye shape that distorts images). Following cataract surgery, many patients achieve 20/20 vision without glasses, even after needing glasses or contacts for most of their lives.

Ultimately, my mom decided to undergo cataract surgery, and it was my honor to perform the procedure myself. She and I felt confident this route would not only be best for her overall health but that it would also improve her quality of life. During surgery, I elected to insert the TECNIS Symfony® IOL (Johnson & Johnson Vision)* which has been available for about two years. This is the first in a new class of advanced lenses called extended depth-of-focus IOLs, which offer a seamless, continuous range of quality vision. In my professional assessment, this was the right choice for her, but every person considering surgery needs to speak with their physician to determine what is best for them.

 

Protect and Monitor Your Vision

Following surgery, my mom was amazed by how clearly she could see and how vibrant colors now appeared, and that she no longer needs her glasses for most activities. She feels it has given her more independence to do the things she loves, like traveling, playing with her grandchildren, and just performing the tasks of daily life. As her son, I take comfort in knowing that she’s seeing clearly and is safer from fall risks. I see patients like my mom every day and encourage children of older adults to talk with their parents and their ophthalmologists to address vision issues.

As you age, it is important to have your vision checked annually so that a doctor can monitor your visual acuity and check for the development of diseases such as cataracts, glaucoma, and macular degeneration. Impaired vision can make driving, moving around, and reading more difficult, so please consult your optometrist or ophthalmologist who can help answer any vision questions you may have. In-between appointments, it’s important to be aware of the following symptoms that might warrant an earlier return visit9:

  • Problems with glare, particularly while driving
  • Difficulty with or needing more light while reading or completing close-up tasks
  • Changes in how you see or distinguish colors
  • Dry eyes or reduced tear production. Women more often experience dry eyes as they age due to hormonal changes
  • Seeing “floaters” or flashes (tiny spots or shadowy images)
  • Loss of side (peripheral) vision (a symptom of glaucoma) or distorted or wavy central vision (a symptom of age-related macular degeneration)

  1. Thanks for pointing out that bifocal glasses can impair depth perception and cause falls. My mother-in-law wears bifocals, and just last week she called us saying she had fallen. Luckily she’s okay, but we definitely want to keep if from happening again if we can. I’ll talk with her about her about considering cataract surgery.

  2. Great article. It is great that the technology on cataract surgery keeps evolving. I did not even realize that the loss of vision resulting from cataracts causes seniors to be more likely to fall. This is just another great reason to go a head and get the surgery if you have cataracts.
