Cataract surgery’s ease and success surprises many.
If you’ve ever driven an old car with cloudy headlights, you know that the amount of light that passes through the lens is reduced. This is the basic principle behind cataracts in the human eye, and most are related to aging.
This week on “Take Care,” Dr. David Chang explains how a cataract forms and what cataract surgery is like, along the benefits of the procedure. Chang, one of the world’s top cataract surgeons, is a clinical professor of optometry at the University of California San Francisco and author of “Cataracts: A Patient’s Guide to Treatment.”

Chang added that as people get older, the lens get stiffer and starts to lose its clarity, eventually to the point of affecting their visual function. That’s when it’s described as a cataract. Once that occurs, an operation is needed to remove it and replace it with an artificial lens that’s permanently implanted.
“But if that’s not done, many people would be surprised to know that you’ll eventually go blind,” Chang says.
Not everyone will have a cataract problem, but Chang says the majority of people will reach a point in their lives where it becomes a big enough issue that needs to be addressed.
The problem is, people’s vision gradually changes over time and they automatically adjust to that, so it is difficult for them to really know if they have a cataract. Chang says that those who undergo cataract surgery tell him how objects and colors are much more definitive than before, meaning it is easier to tell the difference once the surgery happens and the vision change is instant.
Cataracts start with symptoms of frustration of vision, and if diagnosed, Chang recommends considering surgery, as it is almost certain that the symptoms will continue to worsen over time. He says convincing people to go through with the operation is not altogether difficult…….
