Cataract Awareness Month: 3 Types of Cataracts and Treatment Options

June 12th, 2021

These days, aging catches many of us by surprise. There are things we need to know about our health and choices we need to make like cataract surgery. It will make a big difference if we select the right options for our lifestyles and eye health. Choosing the top ophthalmologists in greater Denver at ICON Eyecare is a great way to prepare for these changes.

At some point in your life, probably after age 40, you may notice that your vision has changed in ways besides focus because of a developing cataract. Cataract development can take time, but by 75 about half of the population develops them and requires surgery. Cataracts are the leading cause of preventable blindness and vision loss. There are three types of cataracts:

3 Common Types of Cataract Cases

1. Slow-developing, center-out or nuclear sclerotic cataracts, are the most common.

First signs: any of the cataract symptoms following list.

  • Blurry vision or double vision
  • Depth perception problems
  • Changes in night vision, including seeing “halos”
  • Difficulty seeing in bright sunlight
  • Trouble determining colors
  • Trouble reading
  • Clouding: seeing “clouds” over your eyes when you look in the mirror

2. Slow-Developing Cataracts, More Common with Diabetics

Developing from the outer lens area, diabetics are at higher risk for cortical cataracts.

First signs: as with common cataracts, but especially trouble with glare, blurred vision, and challenges with contrast and depth perception that make it harder to navigate your environment.

3. Fast-Developing Cataracts

Posterior subcapsular cataracts on the rear of the lens develop quickly, in only months. Risk factors include diabetes, extreme nearsightedness, and long-term steroid use,

First signs: most notable are night vision problems, difficulty reading.

What’s Happening in Your Eyes That Causes Cataracts

Are you wondering, “what are cataracts?” and why does your eye get cloudy as they develop? The lenses of your eyes are a combination of liquid and proteins that focus light onto your retinas, where light is converted to nerve messages so your brain can “see.” Over the years, the proteins start to cling to each other, and the lens becomes cloudy, affecting your sight and requiring replacement.

The Good News: Treatment for Cataracts is Typically Straightforward

Cataract surgery involves removing the cloudy lens and inserting a new custom-selected one. It’s painless and takes about 20 minutes with a follow-up visit about a day later. Cataract surgery recovery takes about four weeks, depending on the cataract patient. If both eyes need surgery, the second one will be performed after the first heals.

Once your eye doctor has determined that it’s time to plan cataract surgery, one of your decisions will be what type of replacement lens to choose. Depending on your lifestyle, you may want advanced lenses with wider focal ranges.
