Patients and families often have practical questions about cataracts that go beyond what a routine eye visit can cover: are they preventable, how fast do they progress, what about the surgery decision, and what is life like after surgery? This article answers the most common questions, shares US-specific statistics, and includes illustrative patient scenarios.

Frequently Asked Questions
Are cataracts a normal part of aging?
For most people, yes. By age 80, more than half of all Americans have cataracts or have had cataract surgery. While they are very common with aging, some cataracts develop earlier due to other causes (diabetes, steroid use, eye trauma, genetics).
Are cataracts painful?
No. Cataracts almost always develop painlessly. New eye pain is not typical of cataracts and warrants evaluation for other conditions.
Can cataracts be reversed without surgery?
No. There are currently no proven medications, eye drops, or supplements that reverse cataracts. Surgery (replacing the cloudy lens with an artificial IOL) is the only definitive treatment.
How fast do cataracts grow?
Cataracts usually develop slowly over years. The rate varies widely between individuals. Some progress rapidly over months; many remain stable for long periods. Diabetes and certain medications can accelerate progression.
Can both eyes have cataracts?
Yes, and usually do. Cataracts typically affect both eyes, though often one eye is worse than the other. Surgery is generally performed on one eye at a time, with the second eye scheduled weeks later.
Do I need surgery as soon as cataracts are diagnosed?
No. Many people live with early cataracts for years before surgery is appropriate. Modern US ophthalmologists generally recommend surgery when cataracts meaningfully affect daily activities, not based on a specific vision threshold.
What is the difference between a cataract and macular degeneration?
Cataracts cause cloudy vision from a clouded lens at the front of the eye. Macular degeneration affects the retina at the back of the eye, causing loss of central vision. Both are common in older adults and can coexist. A comprehensive eye exam distinguishes them.
Will glasses help my cataracts?
In early stages, updated glasses often improve vision. As cataracts progress, glasses are less effective. The lens itself is cloudy, and eventually no glasses prescription can fully restore vision until the cataract is removed.
Are there foods or supplements that prevent cataracts?
Diets rich in vegetables, fruits, omega-3 fatty acids, and lutein/zeaxanthin (in leafy greens) are associated with lower cataract risk in epidemiological studies. No specific supplement has been proven to reverse cataracts. A balanced diet supports general eye health.
Does smoking cause cataracts?
Smoking is a strong, well-established risk factor for cataracts. Quitting smoking reduces ongoing damage and may slow progression. The risk reduction is one of many reasons to quit.
Can diabetes cause cataracts?
Yes. Both type 1 and type 2 diabetes increase cataract risk, particularly when blood sugar is poorly controlled. Cataracts in patients with diabetes may develop at younger ages and progress faster. Good diabetes control reduces risk and progression.
Do steroids cause cataracts?
Long-term steroid use (oral prednisone, inhaled steroids for asthma/COPD, prolonged eye drops, injected steroids) is well known to cause posterior subcapsular cataracts. Discuss alternative medications with your prescriber when feasible. Never stop prescribed steroids abruptly without medical guidance.
Can I drive with cataracts?
In early stages, yes. As cataracts progress and cause significant glare or vision loss, driving safely may become difficult, especially at night. Many patients choose surgery when night driving becomes uncomfortable. Always follow your state’s vision requirements for driver licensing.
How long does cataract surgery take?
The procedure itself takes 15 to 30 minutes per eye. Total time at the surgery center is usually 2 to 3 hours including check-in, anesthesia preparation, surgery, and recovery before discharge. For details, see our cataract surgery cluster.
Is cataract surgery covered by Medicare?
Yes. Medicare covers medically necessary cataract surgery with a standard monofocal intraocular lens. Patients with Medicare Advantage or commercial insurance generally have similar coverage. Premium IOLs (multifocal, toric, EDOF) and laser-assisted surgery typically carry additional out-of-pocket costs. See our cataract cost guide.
What is the success rate of cataract surgery?
Cataract surgery has one of the highest success rates in modern medicine. According to AAO and ASCRS data, more than 95 percent of patients achieve significantly improved vision. Major complication rate is low (well under 1-2 percent for serious issues).
Can cataracts come back after surgery?
The lens itself does not regrow. However, the lens capsule (which holds the IOL) can develop cloudiness months to years after surgery, called posterior capsule opacification or “secondary cataract.” This is treated with a quick, painless office YAG laser procedure.
Can children have cataracts?
Yes, though pediatric cataracts are uncommon. They may be congenital (present at birth), genetic, related to maternal infections, trauma, or medical conditions. Early evaluation and treatment by a pediatric ophthalmologist is critical.
Cataracts Statistics in the United States
The following figures are drawn from US sources including the National Eye Institute (NEI), AAO, CDC, and major US ophthalmology databases. They represent population-level estimates that vary by methodology and time period.
- Prevalence: Approximately 24 million Americans aged 40 and older have cataracts (NEI).
- By age 80: More than half of all Americans either have cataracts or have had cataract surgery.
- Surgery volume: Approximately 4 million cataract surgeries are performed annually in the United States, making it one of the most frequent surgeries in the country.
- Outcomes: More than 95 percent of patients achieve significantly improved vision after surgery (AAO and ASCRS data).
- Complication rate: Major complications occur in less than 1-2 percent of cases. The most common are posterior capsule opacification (treatable with YAG laser), inflammation, and rarely retinal complications.
- Surgical approach: The vast majority of US cataract surgeries are performed with phacoemulsification (ultrasound-based lens removal) with foldable IOL implantation as outpatient procedures.
- Sex distribution: Slightly more cataract surgeries are performed in women than men, partly due to longer life expectancy.
- Smoking impact: Smokers have approximately twice the rate of cataract development as non-smokers.
- Diabetes impact: Adults with diabetes have substantially higher cataract risk and earlier age of onset.
- Cost: Cataract surgery with standard monofocal IOL is generally covered by US insurance, including Medicare. See our cost guide for premium IOL pricing.
When to Seek Urgent Eye Care
While cataracts themselves do not warrant emergency care, certain symptoms warrant prompt eye evaluation:
- Sudden vision loss in one or both eyes
- Severe eye pain
- New flashes of light or many new floaters
- Curtain or shadow across vision (possible retinal detachment)
- Sudden double vision
- Severe headache with vision change
- Eye trauma with any visual change
These symptoms can indicate retinal detachment, acute glaucoma, vascular events, or other emergencies — not cataracts.
Patient Scenarios
These short, illustrative scenarios reflect common cataract experiences in the United States. They are educational examples and not real patients.
Margaret, age 68, slowly progressing cataracts. Margaret first noticed glare from oncoming headlights during night driving. Her optometrist diagnosed early bilateral nuclear sclerotic cataracts. She updated her glasses, started wearing polarized sunglasses, and limited night driving. After three years, her vision worsened to where she had difficulty reading restaurant menus and recognizing friends at distance. She decided to proceed with cataract surgery on the worse eye first, then the second eye a month later. At her 1-year follow-up she reports clear vision in both eyes and has resumed all her usual activities.
Robert, age 73, falls and cataract surgery decision. Robert had a fall in his yard and a near-fall on stairs. His eye exam showed moderate cataracts in both eyes plus age-related macular degeneration. His ophthalmologist and primary care doctor both encouraged surgery to reduce fall risk. He had outpatient cataract surgery on the worse eye and reported significantly better contrast and confidence within days. He had the second eye done 6 weeks later. He reports better mobility and no further falls at his 6-month visit.
Linda, age 56, steroid-related cataract. Linda has had asthma for years and has used inhaled corticosteroids long-term. She developed posterior subcapsular cataracts faster than typical for her age. Her ophthalmologist and pulmonologist worked together to optimize her inhaler regimen. She had cataract surgery and continues her asthma medications with new lung specialist supervision. Vision is excellent after surgery; asthma is well-controlled.
James, age 80, watchful waiting then surgery. James was diagnosed with mild cataracts at age 75 and managed with annual eye exams and updated glasses. By 80, his daughter noticed he was hesitant to drive in the evening and rarely read at night. He chose surgery and reports it as the best vision-related decision he ever made.
