What Happens If Cataracts Are Left Untreated?

Untreated Cataract Problems

Currently, no medication or eyedrop has been shown to stop or reverse the formation or cataracts. The only way to treat a cataract is by surgically removing the eye’s natural lens and replacing it with an artificial lens. Modern techniques and technology allow surgeons like Mark Mandel, MD, to remove cataracts in the least invasive way possible. The procedure takes less than an hour and is performed on an outpatient basis.

Although every surgery has risks, leaving cataracts untreated can also be risky. Read on as Dr. Mandel explains what can happen if cataracts go untreated.

Cataracts Will Not Go Away On Their Own

Cataracts do not need to be immediately removed simply because they are present. In the early stages of a cataract, its effect on vision may be minimal, and the cataract may not interfere with daily activities or quality of life.

However, cataracts are a degenerative condition. Left untreated, they will eventually get worse. It is very difficult to predict how quickly cataracts will worsen and vision will deteriorate.

Worsening vision can threaten your safety and wellness. You may be at risk of a devastating fall that could cause a fracture. Also, driving can become very difficult. You put yourself and other drivers at risk of a motor vehicle accident when your vision is limited.

Deteriorating vision due to cataracts can interfere with your everyday activities and hobbies. As cataracts worsen, you may lose the ability to read, watch television, cook, clean or engage in your favorite hobbies. You might start to feel less independent and less social. With time, overall quality of life can decline considerably.

Surgery Could Become More Difficult

Another risk of delaying cataract surgery is that it increases the complexity of the procedure. Generally, cataracts are easier to remove when they first start to become bothersome and affect the activities of daily living. Waiting too long to remove cataracts could make the operation more difficult because the cataracts become very dense.

An experienced cataract surgeon like Mark Mandel, MD, can advise you of the right time to undergo surgery, based on an evaluation of your eyes, vision and symptoms.
