Blindness from Cataracts? Five Questions Answered

Blindness from Cataracts? Five Questions Answered

1. Did you know that cataracts are the leading cause of preventable blindness in the US and even worldwide?

Caused by a clouding of the lens in the eye, cataracts can result in vision loss and have a major impact on quality of life. Cataract-related visual impairment can take away a person’s independence and ability to do every day tasks like drive, cook, or even read.

2. Who is at risk and what are the causes?

Cataracts are not just found in the elderly. Although it may not affect vision at this stage, early signs of cataracts can occur from age 40 and up. Cataracts become progressive and debilitating with age, where almost half of Americans are estimated to have cataracts by the age of 65. Through population-based studies, USC Roski clinicians have also found that a projected 180,000 U.S. Latinos aged 40 and over nationwide have an unmet need for cataract surgery.

Cataracts can be caused by many factors including diseases such as diabetes, exposure to UV light or even smoking and alcohol use. Obesity, high blood pressure, eye injury, or surgery can also result in cataracts.

3. What are the signs?

It is important to recognize the signs. An eye exam is essential if you see halos of light, blurred or poor vision at night, double vision in a single eye or fading yellow of colors. In general, while these symptoms could be related to cataracts, visiting a skilled eye specialist for an evaluation is key to ensuring healthy vision.

4. How to prevent cataracts?

Healthy vision can come from leading a health lifestyle. Quit smoking, eat a well-balanced diet and take care of your health issues by seeing a physician regularly.

5. Cataract surgery – what to expect?

USC Roski cataract surgeons offer the latest advanced technology in cataract extraction. Typically cataract surgery is an outpatient procedure, lasting 30-60 minutes. Cataract surgery entails performing a lens exchange; the surgeon replaces the cloudy cataract lens with a clear lens implant.

In addition to standard lenses, we also offer our patients a large selection of premium lenses that are customizable including, mutifocal, toric and accommodative lenses. USC Roski Eye offers a minimally invasive technique such as femtosecond laser cataract surgery (custom laser cataract surgery) procedure, which allows for more precision in lens removal and gives surgeons the opportunity to treat corneal astigmatism at the time of cataract surgery.
