It’s important to have them checked
Is it time for cataract surgery? It turns out, there are lots of good answers to that question – but only one best choice.
Cataracts, as it turns out, can be taken care of at any time. However, there is one very good reason to be evaluated right away, Dr. Gans says. Cataract-like symptoms may signal other problems – and those mayneed to be addressed immediately.
“The time to have them removed is when a patient notices changes,” he says. “The only problem is, the symptoms can be signs of other eye diseases that are much more time-sensitive. So you have to make sure it’s not something that needs to be treated more quickly and more aggressively.”
The disease, which is the most common cause of vision loss among people over age 40, does not cause permanent damage to the eye. So if patients simply have cataracts and no other eye issues, they have the power to decide when to get cataract treatment, says ophthalmologist Richard Gans, MD.
“The patient’s in the driver’s seat as far as when the time is to have something done,” Dr. Gans says. “Cataracts don’t hurt the eye; they don’t damage the eye in any way. If you see well enough, there’s no rush. If you can’t see well enough, it’s time to get something done,” he says.
When to treat cataracts is very individual. Some people with limited visual needs choose not to have their cataracts removed. Others have 20-20 vision but are troubled by the amount of glare, perhaps due to their profession. They may choose to have something done sooner.
In general, cataracts cause a progressive, slow, steady decline in vision. Cloudy areas spread and intensify over a period of months or years, Dr. Gans says. The signs of their advance vary among the three different types of cataracts.
You may be bothered by glare from headlights and other bright sources of light, halos around bright lights when the surrounding area is dim, decreased color perception or the need for more light to see common objects.
“Patients may experience an inability to read, an inability to drive, or an inability to do the normal things people want to do each day because their vision is getting progressively worse,” Dr. Gans says.
Three types of cataracts
Each of the three types of cataracts has its own somewhat varying symptoms and its own time course. The timing can range from a six-month progression with severe glare and difficulty recognizing faces to a 20-year course that changes overall clarity and ability to see in dim lighting. Cataracts break down into three different types:…….
